Attraction of roses has long pedigree

/in /by

This is the third and final article in a series on roses.

The first article reviewed the groups of commercial roses that are available today and the major characteristics of each group.

The second article covered site selection, bed preparation, planting procedures, as well as good cultural practices for growing roses.

This article addresses the history of the rose.

The rose has long been called “The Queen of Flowers.” Paintings honoring the rose can be traced back as far as 1500 BC to the isle of Crete.

Many famous writers, philosophers, poets, and historians of the ancient world have written about the rose. Homer, the poet who lived almost three thousand years ago, mentioned roses in the “Iliad” and “Odyssey.”

The historian Herodotus, who lived 2500 years ago, remarked on King Midas’ elegant rose garden.

The Chinese philosopher Confucius stated in fifth century BC that there were over 600 books on roses in the emperor’s library.

No other flower, with the possible exception of the lily, has been so connected with history, love, and lore as has the rose.

The rose’s connection with the past civilizations, cultures, and world events all add to its prominence.

The rose’s image has been struck on coins of various nations, and at least one famous war was name after roses.

In 1455 a bitter struggle for the throne of England began between the house of York and the House of Lancaster. The war lasted through the reign of three English Kings. The name “War of the Roses” came from the symbols employed by each side. The House of York symbol was a white rose, and The House of Lancaster symbol was a red rose.

Interestingly, when the two families were later joined in marriage, the two roses were also crossed to produce the white and red Tudor Rose.

There are people of great historical significance who are closely associated with the rose.

The rose garden of the empress Josephine, wife of Napoleon, was so famous that warring English ships were directed to let pass French ships carrying roses for her garden. She sent expeditions to distant places to collect previously unknown species of roses. In this regard Josephine did much to promote the notoriety and evolution of roses. After Josephine’s death, the artist Pierre-Joseph Redoute published three volumes of paintings of her roses entitled “Les Roses.”

The ancient Greeks were likely the first to seriously grow and promote roses. In fact, the “Queen of Flowers” designation can be traced to the Greek poet Sappho, who lived in the sixth century BC.

After Alexander conquered Egypt, the populace quickly adopted roses for both ceremonial events and private fashion. Because of the favorable climate, roses soon became a mayor Egyptian export.

But although it was the Greeks who exported the roses to other Mediterranean lands, it is the Romans with whom we most closely associate early roses.

Roman passion for roses exceeded anything we can imagine today. At one point the Roman obsession with roses nearly ruined their economy. People who had previously grown food in their gardens began growing only roses. There are stories of rose petals piled so deep at Roma parties that on occasion guests died of suffocation. Besides festivities and ceremonies, the Romans used roses to make wines, perfumes, puddings, honey, and jellies.

The fascinating stories of the rose are an added bonus for the avid gardener who also appreciates history. Roses with a particular claim to fame can still be found and purchased.

Walking through your garden and retelling the story of a special rose you have planted is just another avenue of enjoyment for those of us who love roses.

Growing roses can bring satisfaction to homeowners

/in /by

For the homeowner who enjoys gardening, an immense amount of satisfaction can come from growing roses.
Regardless of individual preferences, roses offer something for everyone.
They can be found in every color, shape and size imaginable.

Roses can be used in landscape designs ranging from casual to extremely formal.
Enjoyment of roses does not end in the garden, either.
Cut rose arrangements from one’s own garden can spice up a room’s décor and impress visitors to the home.

Contrary to widely held beliefs, it is not necessary to be an expert to grow impressive roses.

Admittedly, more elegant roses like the hybrid teas take extra care, but they too can be grown successfully by anyone who has an interest in them.

Fortunately, although the degree of maintenance varies with the species selected, general rules for rose care apply across the different groups.

Some research on the correct planting and care of roses prior to purchasing will be immensely helpful to the home gardener’s long-term success.

In our last blog, we reviewed the attributes of roses in most of the major groups of modern roses.
Don’t worry if you missed it, you can find it here.

Several good web articles, rose books and reference manuals are available that detail the qualities and disadvantages of each group, along with pictures of numerous individual varieties. Keep in mind, however that rose selection is only the first step to successful rose growing.

Choosing the proper location, and correctly preparing the planting bed, will have a great impact on the future success of the roses.

Practically all roses like full sun. Select a location that has at least morning to mid-day sun. Roses need good air movement, too.

It is best not to box them in between buildings, walls, hills, or trees and shrubs. In the latter example, these other landscape plants can compete with the roses for both water and nutrients.

Roses like to be well watered, but the planting bed must drain well for roses to thrive. Building a raised bed or planting in a high location is the best way to insure good drainage.

If this is not feasible, putting a drain line blanketed in gravel is an option. In many areas, of course, the native soil drains sufficiently well that there is no problem.

If there is any doubt, fill the hole with water before planting to see how well it drains. Most of the water should be gone in a few hours. If it is not, then something additional needs to be done regarding drainage.

For the novice rose grower, it is recommended that container roses be selected instead of bare-root roses. It is easier to see what you are getting, and they are easier to establish after planting as well. Still, extreme care should be taken when moving the plant from the container to the planting hole. If the roots are not mature enough to hold the root ball tightly together, be prepared to cut the bottom from the container. Then, after setting the can in the hole, cut away the sides. Avoid planting the heat of the day. Late afternoons or mornings are best. When purchasing new roses, check with the nursery on the best· amendments for your particular soil.

Composts or peat moss are good choices. They help adjust the soil pH to a more acidic level, which is better for rose growth. In cases where the soil is highly alkaline, agricultural Sulphur can also be used to acidify the soil and lower the pH.

After planting roses, adding mulch to the soil surface is a good idea. It is both beneficial and attractive. The mulches referred to here are organic materials. Mulches can also be in­organic materials, such as crushed stone and black plastic, but they are not recommended for rose beds. Good mulch choices are small bark chips or composts from plant materials. They retain the moisture, keep weeds down and add some color and nutrient value to the soil. These materials generally have a pleasing aroma and make walking through the bed a pleasure.

Once roses are planted, they need to be fertilized periodically. Again, the higher maintenance hybrid teas and the floribundas, which are the showcase roses, need more fertility than the older rose species. Most nurseries and landscape supply companies will offer special formulations for roses. Dry fertilizers are usually a better buy and easier to apply. Agricultural and horticultural fertilizer formulations can be substituted for the special rose blends. Ask for a balanced fertilizer that is not excessively high in nitrogen. The material should also contain all the secondary and trace elements. In regards to pests. on roses, healthy plants are the best defense against problems. Fortunately, the arid and semi-arid climates of the Southwest spare us from the more severe problems with bacterial and fungal diseases. Many of the insect pests can be controlled with systemic materials, where the chemical is applied to the soil and subsequently absorbed into the plant. If a problem persists, take a leaf sample to a Cooperative Extension agent, a pest control advisor, or a local nursery.

Pruning is probably the most intimidating part of growing roses for the novice. Fortunately for the beginner, roses are forgiving plants in regards to pruning. Mistakes are seldom serious and almost never fatal. The majority of rose pruning is done before the plant breaks dormancy. In the Southwest that generally means January or February. In extreme cold climates, heavy pruning may be done as late as April. Such winter pruning means reducing the plant to a few canes that are cut down to six inches to a foot or so in height. Cuts are made at a forty-five degree angle one-quarter inch above an out facing bud.

Skills in pruning and other cultural practices will be fine-tuned over time. As one learns more about roses through experience, observation, reading, and asking questions, a confidence level will build. Growing roses can be successful and personally rewarding from the beginning.

 

Roses Can Be Versatile And Beautiful

/in /by
Roses add a touch of elegance to the home garden or landscape. Roses are very versatile and there is a tremendous selection from which to choose. They can be used for almost all landscape purposes, with the exception of providing shade. In fact, a rose exists for practically every landscape design feature that requires the use of ornamental plants. And contrary to popular belief, roses do not necessarily require large amount of time or talent to be grown successfully.

Modern-day roses can be separated into five general categories.

Beginning with the most prevalent, the group includes hybrid tea roses, floribunda roses, climber and rambler roses, shrub roses, and miniature roses. While this method of grouping hardly tells the whole rose story, it does help the homeowner narrow the search to the class of group of roses that has the desired characteristics.

The Hybrid Tea is the most popular of all the roses. We think of the hybrid tea as the classic rose bloom – it is the one we purchase be the dozen from the florist. Knowing their popularity, it is somewhat surprising to learn that hybrid tea roses were not developed until the year 1867.

Rose breeding had been going on long before, but it was the introduction of Chinese roses the Western World that allowed breeders to make a giant leap in the development of new rose varieties. The first hybrid tea rose was cross between a Chinese tea rose and a hybrid perpetual.

If you are planning on taking cuttings for flower arrangements or if you are looking for a formal look, then the hybrid tea rose is certainty the way to go.

At my own home, I have 20 “Mister Lincoln” hybrid tea roses planted in perfect rows in a raised bed. With the rapid development of new hybrids, “Mister Lincoln” has now become a somewhat older variety. But I love the deep red color of the blooms and the long stems. Of course, hybrid teas can be planted in less formal arrangements and in a wide variety of colors.

On the down side, hybrid teas bloom less frequently and less prolifically than the next group we will discuss, the floribundas. As a precaution when choosing hybrid tea roses, whose claim to fame are their blooms, make your selection from live plants if possible, not photographs of the flowers. While the individual flowers may be magnificent, the blooms can sometimes be disappointing in number and short-lived. Also, it is important that you like the actual plant and that it fits well into the available planting space. For example, the variety I chose, “Mister Lincoln”, is too tall and open for a small planting bed.

The floribundas are the next group. They are a 20thcentury addition to the family of roses. They came into popularity in the 1950s, although they were developed decades earlier. The fact that a hybrid tea rose was one of the floribunda parents demonstrates the continuing evolution of commercial roses.

As the name floribunda implies, they produce abundance of beautiful flowers. They generally produce several more flowers per bush than hybrid teas and the blooms last considerably longer. Additionally, the floribundas are hardier and require less maintenance than the hybrid teas. The downside is that the floribundas lack the classic beauty and floral fragrance of hybrid teas. However, newer floribunda varieties are starting to overcome these drawbacks. No doubt we will continue to see breakthroughs in rose development.

While Hybrid teas and floribundas are relative newcomers, climbers and ramblers have been around for a long time. Climbers have been used for centuries to cover houses, walls, fences, and other vertical structures. Ramblers became popular in the Victorian era and were probably in common usage much earlier. Ramblers can be used as climbers but their stems are smaller and less rigid than the roses that are designated as climbers. Although in both cases the stems must be tied to the structure or otherwise supported.

Climbers are usually a better choice than ramblers. They are hardier and have larger and more prolific blooms. The thicker stems make them better adapted to vertical growth. Some hybrid tea varieties have been converted to climbers but the same precautions apply, consider the plant as well as the flower. There may be fewer blooms on hybrid tea climbers than you would like to see.

Shrub roses are sometimes referred to as “old-fashioned” roses. Although they have also been improved for garden through hybridization, much of their parent history is from ancient or wild rose species. As a general rule, expect this group to be extremely hardy and need little care. Certain varieties can even be used as ground-cover.

Miniature roses also disappeared from the scene in the early 1900s but since have had a popular resurgence. They can be grown in window boxes, serve as the border of flower beds or used in numerous other specialized applications.

Although more common now than in the past, there are still novel enough to draw attention and conversation.

Tree roses are also popular, but they are not a separate group. They can be trained from hybrid teas and floribundas in particular, as well as from some other groups.

Other subgroups and specific use roses can easily be researched and obtained by the interested gardener or homeowner.

The popularity of roses has led to an infinite amount of information that is readily available.

In preparation to writing this article, I discover I had six books in my home library dedicated entirely to roses, as well as chapters and sections on roses in other gardening books.

In the next blog we will talk about the proper planting and subsequent care of roses.

 

 

 

California's Groundwater

California’s Groundwater

/in /by

The management and preservation of Groundwater has become an urgent topic in California’s water plan.

Groundwater provides an important adjunct to the State’s rainfall, snow melt, and Colorado River import. As with surface storage, underground reservoirs have the potential to store huge volumes of water that can be relatively easily accessed. According to the California Water Atlas, a somewhat dated but still a pertinent and comprehensive water data reference, the total groundwater on earth is more than 30 times as much as all the water in lakes and rivers, plus all the moisture in soils and in the atmosphere. The largest groundwater reservoir in California is the Central Valley Reservoir, with has a usable storage capacity estimated at 100 million acre-feet. When taken as a single encompassing reservoir, it lies beneath a not always contiguous 15,000 square-mile area. In fact, it is the equivalent to the total area of the other 50 groundwater reservoirs from which significant volumes of water are pumped.

Groundwater extraction provides a reliable and moderating influence of the boom/bust cycle of winter surplus and summer deficiency that comes from winter rains, followed almost invariable in Southern California by summer drought. If we are fortunate, seasonal rains will exceed the retention capacity of the soil, causing at least some of the water to percolate downward until it reaches the saturation zone and becomes part of the groundwater supply. Still, even with some degree of recharge, this groundwater supply is not inexhaustible. Pressure from the addition of new wells and over-pumping of existing wells, have led to a startling diminishment of groundwater supplies.

New protections and groundwater regulations are on the horizon. Efforts will be made to provide additional recharge for depleting reservoirs. Limits will almost assuredly be placed on how much water can be taken from saturation zones, and begin watching for stringent new rules on the application of fertilizers and other materials that can negatively impact the quality of groundwater.

Water Audits Procedures

/in /by

WBA conducts water audits for all sizes of turfgrass and landscape. A client can expect the following steps to be completed and a detailed compilation of reports to be submitted.

Initial Visit

An initial visit to the designated area will be done; meeting with the superintendent and maintenance staff. An area will be selected to conduct the water audit, and the following information will be obtained:

  1. The Irrigation Controller will be identified.
  2. The clocks will be activated and all sprinklers will be flagged. Each sprinkler will be checked for proper operation, and adjustment.
  3. A field test area data map will be drawn. Sprinkler operating pressure, static pressure, dynamic pressure, and sprinkler head spacing will be recorded.
  4. A soil probe will be used to determine root depth, thatch layer buildup, organic matter accumulation, and the soil moisture content.
  5. The number of catch devices will be determined for use on the lawn surface when performing the catch can test. Each catch location will be recorded on the map.
  6. A programmed run time will be used to collect water in the catch devices.
  7. Water volumes will be read and logged on the test area map.
  8. The distribution uniformity and precipitation rate will be calculated and recorded.
  9. The irrigation controller and backflow information will be documented.
  10. The current water schedule for the turf zone will be verified.
  11. After discussing the sprinkler uniformity with the supervisor or superintendent, it will be decided if there is a need to retrofit the current spray nozzles with more uniform rotating nozzles.

Second Visit

A second visit will be conducted and at that time, if there is a need to retrofit spray nozzles, it will be performed at this time. The following procedures will be performed and the resulting information will be collected:

  1. The clock will be activated and all sprinklers will be checked for proper operation, adjustment, and operating pressures.
  2. The decided number of catch devices will be placed on the lawn surface and separate columns will be used to distribute all of the catch devices.
  3. A programmed run time will be used to collect water in the catch devices.
  4. Water volumes will be read and logged on the test area map.
  5. The distribution uniformity and precipitation rate will be calculated.
  6. An irrigation schedule will be developed utilizing the plant water requirement, sprinkler performance, and soil-water properties.
  7. Properly managing an irrigation schedule will incorporate the following scheduling factors.
  • The proper amount of water (considering weather and turf).
  • The proper frequency of irrigation (based on the soil’s ability to store water and the intake rate of the soil).
  • The performance characteristics of the irrigation system (how quickly and evenly water is applied to the turfgrass).
  • The features of the irrigation controller and the characteristics of the site that determine appropriate program start times and maximum station run times without runoff.

TURFGRASS AND LANDSCAPE IRRIGATION AUDIT

 

 

 

Irrigation Water Quality

/in , /by

A thorough understanding of irrigation water quality is very important to the successful management of turf sites.

Understanding such major water quality factors as pH, nutrient content, alkalinity, salinity and the concentration of elements and compounds toxic to turf is crucial when developing cultural practices programs. Information regarding irrigation water quality is also very important when selecting turf species for the site.

While testing the soil for information in the above-mentioned areas is common practice, testing of the irrigation water is frequently overlooked. Actually, soil and water quality testing go hand in hand. Soil acts as filter or sponge, trapping the negative elements in the water in upper inches of the soil profile. Irrigation water does one of three things when applied to a turf site – evaporate from the soil surface, percolate through the soil profile, or is utilized for plant growth. In all of these cases, many of the undesirable elements and compounds are left in the root zone of the soil profile.

Repeated applications of poor quality irrigation water can eventually raise the concentration of these unwanted elements to levels that are toxic to the plant. This is especially true where the soil drains poorly or is already high in salts or other negative materials. So in addition to a nutrient and chemical analysis, it is valuable to do physical testing of the soil to determine soil particle size and distribution. The physical analysis will also estimate infiltration and percolation rates. This information helps tremendously in deciding the type and quantity of soil amendments, as well as the necessity of installing drainage systems in the turf and landscape areas. Soils that drain well allow for the undesirable elements to the leached or rinsed from the soil through the application of additional irrigation water.

Irrigation Water Quality

 

Irrigation water testing results can be matched to a chart that categorizes concentrations of different materials. A text entitled Salt-Affected Turfgrass Sites-assessment and management by R.N. Carrow and R.R. Duncan is an excellent reference. It is available through both the Golf Course Superintendents Association of America in Lawrence, Kansas, and the publisher, Ann Arbor Press, located in Chelsea, Michigan. The book deals extensively with both soil and water quality issues and their relationship.

Looking at the different analyses derived from irrigation water testing, the pH reading is a measurement of the degree of acidity or alkalinity of the water. The pH is measured on a scale of 0 –14 with a neutrality level of 7.0. Problems with pH extremes in the Southwest are almost invariable from readings on the high or alkaline side. The number measurements for pH are logarithmic, meaning that each number represents an increase in concentration of 10 times the previous number. In other words, 8.0 is 10 times great than 7.0, and 9.0 is 100 times greater than 7.0 in terms of alkalinity. The same is true with acidity, 6.0 is 10 times greater than 7.0, and so on. Extremely high pH, our primary concern, can be reduced if necessary. The primary method of achieving pH reduction of irrigating for large turf areas is through the injection of sulfuric acid.

An important category to note on an irrigation water sample report is the level of sodium and total salts. Sodium is listed separately from other salts because it has the ability to destroy soil structure as well as impact the health of the plant. Sodium concentration is listed as milliequivalents per liter. The sodium risk can be greatly buffered by concentrations of calicum and magnesium in the water. The comparison formula is called the Sodium Absorption Ratio, and the lower the number the better.

Total salinity can be listed as either Total Dissolved Salts (TDS) or as Electrical Conductivity (EC). If listed as TDS then divide by 640 to find the EC. If EC is listed, then multiply by 640 to find the TDS reading. Salts from irrigation water can accumulate in soils and cause a condition detrimental to plants called “physiological drought”, where water is present but unavailable to the plant. The rule of thumb is that an additional 12.5 percent of irrigation water is required for each 1.0 elevation in EC to provide for adequate leaching of salts from the soil profile. Salt tolerance levels vary greatly with different turf species. Knowing the salt levels in irrigation water can be tremendously helpful when selecting a turf species for a particular site or facility.

Carbonates and Bicarbonates are other detrimental compounds in irrigation water. Their presence is frequently in association with high alkalinity. Reducing the pH in extreme situations will also have the benefit of offsetting the effects of carbonates and bicarbonates. Testing the water to determine the levels of these and other compounds listed above will be a great advantage in the quest for healthy turf.

Golf in Cuba: Part II

/in , /by

Written by William Baker, WBA Principal.

Cubans who are involved in the country’s very limited golf industry have high hopes for the future. There are suggestions that up to 20 new golf course could be built along the north-facing shores of the island. In other words, those locations closest to Miami and other regions of the U.S. It is unclear that this is real possibility. World class golf is accessible, with better amenities, only an island away in the Dominican Republic. Those courses can be breathtaking in their design, conditioning, and seaside settings. In this regard, Cuba will have a lot of catching up to do.

As mentioned in a previous post, there is only one 18 hole golf course in Cuba – Varadero Golf Club. It is an impressive layout with some interesting history, but lacking in the tournament level conditioning that we have come to expect from top destination resorts. That will have to change to bring American players to the island in great numbers.

Several hotels in the area promote themselves as golf resorts. One might expect from the advertisements that each hotel / resort has its own golf course.   But apparently they are all sharing the one course on the Varadero peninsula. Golf destination travel usually allows for experiencing a variety of good courses. Using the Dominican Republic again (due to its proximity to Cuba), a number of beautiful and challenging courses can be found in the Punta Cana region. About 40 miles away, near the city of La Romana, six golf courses can be found inside the Casa de Campo Resort. One of these, “Teeth of the Dog”, is consistently rated in the “Top 100” in the World by Golf Digest.

One of the great challenges to golf expansion is Cuba is almost the total absence of Cuban players. In preparation for an international tournament at the Club earlier this year, they were unable to field a team of 50 golfers from across the country. This will change, but it will take time. There is clearly great enthusiasm for golf tourism from the U.S. to develop. But hopefully the uniqueness of the island and the wonderful culture will not be lost in the coming commercialization.

Technical Feasibility of a Project

Golf In Cuba: Part I

/in , /by

Written by William Baker, WBA Principal.

There is only one 18 hole golf course in Cuba. It is located in the tourist zone of Varadero, about a two-hour drive from Havana. It is a great layout. The course opened in 1933, as part of the private estate of French American millionaire Irenee Dupont de Nemours. He was the chairman of the Dupont Company. He retired in 1927, when he was 49 years old. Looking for a place to spend his leisure years, he purchased 450 acres of land o the Hicacos Peninsula and started building a retirement paradise.

The home he built there remains part of the golf course property, serving now as a small hotel with an elegant bar and restaurant. It’s a fascinating place, with four floors, 11 bedrooms, three large terrance, seven balconies, and a private dock. Rooms are available for stays at a very reasonable price.

The golf holes along the beach and surf are reminiscent of other great courses in the Caribbean Islands. But the course feels more like a well-kept secret, probably due to the inability for most US golfers to play there for the past several decades.   Current playing conditions would be on par with relatively good municipal golf courses in the States. One can only imagine the difficulty of keeping conditions even at this level with no industry support, or even any Cuban golfers.   About 90 percent of the players are Canadians that venture to Cuba during the cold winter months at home. Others are mostly European tourists.

Several large hotels are on the peninsula, with most of them requiring the purchase of an inclusive package. Smaller hotels and rooms can be found in the little town of Varadero, a couple of miles away. The beaches are very accessible, with white sand and water a soothing color of blue. Lots of small shops and bazaars with numerous booths are along the main street.

The people are fascinated with Americans, since they have seen so few of them. People are friendly and helpful wherever you go. Canadians are common to see in the winter months. They often mistake Americans for fellow Canadians. Crime seems low in Cuba, and this is especially true in Varadero. One can walk in the evening in the downtown area to local clubs and restaurants, without having any anxiety in doing so.

Why Smart Controllers Rock

/in /by

By Lori D. Palmquist, CID, CIC, CLIA, CLWM

Smart irrigation controllers rock! How do I know? I’ve installed 30 of them (12 different models), and I’m seeing terrific results. On the average, I’ve seen them lower water consumption by 40 percent. Smart controllers, also known as ET controllers and weather-based controllers, respond to daily changes in the weather by adjusting either the runtime of the individual irrigation zones, or the watering days, or both.

Smart irrigation controllers have revolutionized the way we water our landscapes. The old behavior of programming irrigation controllers for existing conditions, and leaving that schedule until someone returns to change it, is becoming a thing of the past.

It is a generally accepted statistic that we overwater our landscapes by a margin of 200%. There is a great need for the use of controllers that adjust their schedules daily, in response to weather conditions.

The current trend is toward state legislation requiring weather-based irrigation controllers.

An important point needs to be made here. Inefficient, problem-riddled irrigation components will not magically improve their performance, if a smart controller is installed. If anything, a smart controller will very quickly reveal the weaknesses of an inefficient or faulty system.

When an irrigation system has bad coverage, due to poor design or broken, sunken, tilted, or blocked sprinklers, traditionally we have added more runtime minutes to apply more water, resulting in significant water-waste. Smart controllers are very different from standard controllers, in that they have no feature to allow the user to simply “add minutes.” If you want a smart controller to compensate for irrigation inefficiency, you have to learn how to program it in such a way as to “outsmart” it, as it is programmed to behave in efficient ways only.

There are two sources of weather data that inform smart controllers. One is professional grade, off-site weather stations. The smart controllers that access off-site weather data often have a monthly, small fee for the acquisition and delivery of the data. The other source of weather data is on-site weather sensors, monitors, and soil-moisture sensors. This strategy involves buying the equipment up front, with no on-going, data-service fees.

There are more than 30 weather-based smart controllers and several soil-sensor-based controllers on an approved list from Smart Water Application Technologies or SWAT. It can be daunting to know how to decide which controller would be the most appropriate in any given situation.

Following are some of the factors for you to consider when deciding which controller is the best one for the job:

  • Size of landscape
  • Number of controllers needed for the landscape
  • Budget
  • Ability of a pager or cell phone tower signal to reach the controller (signal strength)
  • Importance of accuracy of the data
  • Whether up-front costs (on-site data gathering) or on-going fees (off-site data gathering) are preferred
  • Whether you are hands-on, or want the installer to monitor and maintain the system
  • Which controller you (or the installer) feel confident using

Good Tip: The best way to determine which controller to choose is to consult with someone in your area who has hands-on experience with a number of different controllers. Contacting a local water purveyor, professional irrigation supply store, or landscape contractor trade organization, are a few possibilities.

Smart controllers are the future of irrigation scheduling. Some states already require them for new landscape installations. There are also many rebate programs offered by cities and water purveyors for retrofitting this technology into existing systems.

Know that there is a learning curve to understand installation, usage, and monitoring of irrigation systems that use smart technology. Many manufacturers offer extensive tutorial videos and literature on their websites. The manufacturers’ reps and technical support crews are also extremely helpful in ensuring that the controllers are installed and monitored properly.

I am having tremendous success with smart controllers, and endorse them wholeheartedly. I also applaud and appreciate the considerable efforts of manufacturers to produce effective and user-friendly systems. I see how proud my clients are to know that they are stewards of our earth’s resources. They’re also happy to lower their water bills. The fact that we can witness irrigation systems responding daily to changing weather conditions is an awesome notion to me.

mosquito abatement

Mosquito Abatement

/in , /by

William Baker and Associates LLC (WBA) are developing mosquito abatement programs for preferred clients. Elements of the program include methods for controlling mosquitoes and the associated risks, teaching staff to recognize mosquito habitat and infestations, holding open meetings to increase public awareness of West Nile Virus and other mosquito-related diseases, and assisting staff in locating qualified companies for contract applications of pesticides approved for mosquito control through the California Department of Pesticide Regulation (DPR).

Program Development:
  • WBA will provide a written abatement program that attacks mosquitoes on several levels. These control methods include reduction of breeding areas, monitoring for infestations, instituting the relatively safer biological controls whenever feasible, and the minimal use of the least toxic pesticides that will give effective control of mosquito adults and mosquito larvae. WBA can provide written recommendations for pesticide applications when it is determined to be the best option.
  • Staff training will be conducted on how to recognize and reduce mosquito habitat on an ongoing basis. If the client chooses to have staff apply their own materials, then WBA can provide training for that. If contracting it out is a better option, then WBA can assist the client in locating qualified and properly licensed companies. In either case WBA can advise on notification of pesticide applications to residents and others in the area, pesticide materials storage, record keeping, and correct reporting procedures.
  • WBA specializes in training programs particularly with parks staffs, public works staffs, golf course staffs, and others in the landscape and green industry. Additionally, WBA personnel have recently conducted 35 separate workshops for industry professionals, with at least 10 more in the planning stages. WBA staff is involved in the development of regional or annual conferences that often have several hundred attendees. WBA is well qualified to conduct large public meetings or informational workshops related to mosquito control and the West Nile Virus.
  • WBA will provide follow-up site visits and reports to measure the program’s success. The program and its guidelines can be amended periodically to address changes in the risk of mosquito transmittable dis- eases, changes in mosquito control methods or technologies, changes in State policies regarding mosquitoes and related diseases, and/or changes in the State or Federal laws and regulations.
