MISSION STATEMENTThe Nevada Landscape Association provides leadership by promoting professionalism and integrity within the Green Industry through education, high standards and community involvement. We guide policy and uphold responsible resource management for the beautification and enhancement of our community.

Integrated Pest Management is a decision-based strategy that relies on a range of pest management tools, selection of which is dependent on the pest, the needs of the site and pre-set thresholds. Practitioners of IPM look at the whole landscape as an integrated system, and evaluate the health of the system to assure appropriate checks and balances exist to keep pests under control. Prevention is emphasized in IPM. Read more on page 4.

A Letter from the PresidentMy Fellow Members,

I am currently writing this letter from somewhere in central Nevada, where the winds have finally deposited me. I now know how Dorothy felt on her trip to Oz, except that I think I am closer to Gabbs, and the two places seem vastly different…Obviously, we all have to deal with a myriad of unforeseen elements throughout

the year and this year’s winds have been no different. There are so many aspects of the landscaper’s life that revolve around calm days; from spraying and fertilizing to mowing and blowing. We are at the weather’s mercy unfortunately, and after a tough winter nothing spells relief like a couple of months of healthy wind.

The NLA has been ticking along at what I would call a “Slightly better than brisk” pace. We actually have a number of issues on the docket that we are trying to find resolutions for and invite you to join us at our August meeting if you would like to help solve those issues. We sponsored the 2012 Water and Rails tour that supports ALS of Nevada, and hope that we can continue to take part in events that support both landscapers and charities in our neck of the woods.

Have a good one and keep everything well tied down!

» Tree Roots & Soil Volume By Brian S. DeanConsulting Arborist

Quick Facts• Infrastructuredamagecausedbytreerootscostsmillionsof

dollars per year to repair.• Withoutsufficientsoilspaceforrootstogrow,treeswillbe

stunted, decline, die and/or eventually cause damage to hardscaping.

• Landscapedesigners,architectsandcontractorsneedtobeproactive to provide enough soil volume for mature tree growth and development.

OverviewTree roots have estimated to cost $70.7 million annually in California to repair infrastructure damage (McPherson 2000). This does not include lawsuits involving injury or contractor defect. The average life span of a street tree growing in New York City is estimated at 3 to 15 years (Bassuk and Trowbridge). Street trees are exposed to increased air temperatures (+20 degrees Fahrenheit) and 30% less humidity than a comparable measurement taken in a sheltered park site (Cornell University). This causes street trees to transpire about 1.5 to 2 times as much as a forest tree (Kopinga) therefore requiring more water to survive.

Trees planted in narrow strips, small planters or “tree coffins” are an all too familiar problem for arborists and landscapers. When too little space is allocated for root systems to develop naturally, damage to surrounding hardscaping can be expected. The limited root growth also correlates to canopy growth and therefore tree health. It can be a serious problem when trees with shallow/invasive roots are planted in these spaces. Small planting areas with compacted soil limit water and oxygen and therefore inhibit root growth. These small open beds concentrate salt, oil and other contaminates that eventually drain into them creating a toxic environment for roots. A properly selected tree for the location will save money and labor for years to come.

Root Growth of TreesStudies show that tree roots grow within the top 18” of soil and are capable of growing two to ten times the area beneath the canopy (Matheny and Clark 1998) and can spread more than twice the width of the canopy (Casey Trees 2008) or one and a half times the height of the tree out radial from the trunk. A trees’ ability to develop a healthy root system is dependent on soil volume. Without sufficient space for root growth trees will lack vigor, exhibit stunted growth, become susceptible to insects, disease, and drought and therefore short lived. In the absence of adequate soil space, roots will exploit available air pockets within the soil. Roots grow where there is adequate water and oxygen. If a tree is confined to a finite space or soil volume it is expected

that the canopy spread will only grow proportionately as the roots are allowed. The tree will stop growing, decline and/or eventually die. While the tree is alive the roots will exploit pore space and possibly cause damage to surrounding infrastructure. According to McPherson and Peper “Tree roots are opportunists, utilizing structural faults in infrastructure to capture essential resources”. Kopinga states “Even small diameter roots are able to facilitate pavement damage”. Soil characteristics such as texture, moisture content, structure and percent organic matter also play a role in how and where roots will grow.

A good source to find trees with high potential for root damage is the “Urban Forest ecosystems Institute” (UFEI) web site. The “SelecTree” guide located at the UFEI web site rates trees that are high, moderate and low in root damage potential. Below are just a few trees listed as high to moderate damage potential that grow in northern and southern Nevada.

Soil Volume RecommendationsThere are many sources for soil volume recommendations and formulas in the literature that produce varied results. Some formulas use “crown projection” or square foot of canopy area projected on the ground. Others use measurements of canopy volume or the diameter of the trunk to establish soil volume. All formulas have merit however the direct relationship of canopy volume, trunk diameter or crown projection to root volume can be argued.

A commonly used formula is providing 2 cubic feet for every square foot of mature canopy or “crown projection” of a tree (Lindsey and Bassuk 1991). For example; a mature Silver Maple will spread to a width of greater than 60 feet. Sixty feet x sixty feet = 3,600 square feet x .7854 = 2,827 square feet x 2 cubic feet = 5,654 cubic feet. This formula does not work if the tree has a columnar growth habit such as Lombardy Poplar or Italian Cypress. Another formula by Perry (1982) uses the diameter of the trunk to estimate soil volume. This calculation states that for every 1” of trunk caliper measured at 4.5 feet above grade or diameter at breast height (DBH) needs 27 ft3 of soil volume. James Urban (2008) uses a combination of projected canopy and DBH based on the potential ultimate size of a tree (see table 1).

Table 1. Tree size to soil volume relationships (Urban 2008).

It should be noted that it is assumed drainage is adequate at the bottom of the soil column.

Root BarriersInstallation of root barriers has often been used as a solution to prevent infrastructure damage. With over 25 years of research their effectiveness has shown that the roots eventually grow out the bottom of the barriers and return in reduced numbers and size to the surface where they naturally would grow. Harris, Clark and Matheny (2004) note that “root-control devises appear to be least effective where most needed, that is, where poor soil aeration or compaction encourages shallow rooting”. Other observations indicate structural stability may also be compromised especially in trees with dense canopies (Pittenger 2001). However, research by Smiley, Key and Greico (2000) growing Green ash showed more force was used to pull over trees in barriers as opposed to no barriers.

ConclusionLandscape designers, architects and contractors need to be proactive regarding the needs of tree roots and the space they require prior to design and planting. The consequences will mean increased maintenance costs, create infrastructure damage, poor tree health, reduce the aesthetics of a landscape and possible liability.

Green Industry Members in Reno-Carson City Area Have Increased Their Use of Integrated Pest Management PracticesBy Heidi Kratsch, Horticulture Specialist, University of Nevada Cooperative Extension

A team at University of Nevada Cooperative Extension performed a survey to assess the use of integrated pest management practices (IPM) by green industry members in the Reno-Carson City area. The survey was funded by a grant through USDA Na-

tional Institute of Food and Agriculture’s Extension Integrated Pest Management Coordina-tion and Support Program. The survey was part of a larger survey of the general home-owner population in our area, the results of which will help us develop effective messages and tools to increase understanding and use of IPM principles in home landscapes.

Results of the green industry survey indicated that western Nevada green industry members have a pretty good understanding of most IPM principles and use them in their practice. Two-thirds of survey respondents use regular scouting for pests to determine when and if pest management is necessary. Scouting, or monitoring, for pests in a land-scape is one of the first and primary tools an IPM practitioner has for determining whether management is needed in a given situation. Almost 40 percent of survey respondents reported using pre-determined pest thresholds for deciding when to treat. A pest threshold refers to the point at which the population of a pest (insect, weed, etc.) becomes an eco-nomic or plant health threat in a given landscape. This threshold is necessarily subjective, but it forces a professional and/or the homeowner to make decisions ahead of time about what will be tolerated. One or a few insects in a landscape can likely be handled by natural enemies, such as beneficial insects or birds, and damage that is only aesthetic may be tolerated as long as the health of a plant is not at risk.

Although only 20 percent of survey respondents reported educating their clients about IPM principles, almost half tailor their approach to the needs of a specific site. This is a recommended approach because each site or landscape is unique, and the pest thresholds and management strategies will depend upon many factors, including the primary site use and type of pest. For example, weed management strategies depend on identification of the weed species, its life cycle and its status as either a noxious or nuisance weed.

Integrated pest management is a decision-based strategy that relies on a range of pest management tools, selection of which is dependent on the pest, the needs of the site and pre-set thresholds. Over 80 percent of local green industry survey respondents knew that. Practitioners of IPM look at the whole landscape as an integrated system, and evaluate the health of the system to assure appropriate checks and balances exist to keep pests under control. Prevention is emphasized in IPM. Only when the system goes out of balance is control implemented, and then a strategy that disrupts the system least is chosen as a first line of defense. Soft chemicals and/or targeted controls (such as Bt pesticides) are used primarily. Broadcast spraying of non-specific pesticides is a last resort, although in some cases, these may be the only effective control strategy for some pests.

An interesting finding from this survey is that over half of local green industry survey respondents are using IPM techniques more frequently than they did five years ago, and public attitudes about use of pesticides may be driving that change. However, almost half of survey respondents reported that client preferences are the greatest barrier to use of IPM techniques, so it appears that we will need to work together over the next few years to better educate the public about IPM and its benefit to our landscapes and the environment. We invite your comments and suggestions as we move forward to develop an educational strategy to that end. Contact us at 775-784-4848 or [email protected].

Alert! Spider mite season is here!

3 Spider mites love the hot, dry, dusty conditions of summer. 3 Classic symptoms of spider mite infestation are bronzing and dusty looking foliage with injury to the leaves.3 Spider mites are most commonly found on junipers, Alberta spruce and other evergreens.3 A great non-chemical control method is to spray the affected plants down with water in the morning or late

afternoon at least once a week. Soap solutions are also a ‘least toxic method’ and work well.

This tree was planted by a professional landscape company. It is planted 7 inches too deep in clay soil and died three years after planting.

This tree was planted 6 inches too deep, improperly staked and then girdled from string trimmer damage—all by the same, well known landscape company.

Don’t Murder Trees! By Holly Bromley, B.S.

Horticultural Consultant and ISA Certified Arborist (#WE-5339)

Murder? OK, it might be a strong word, and a bit dramatic when talking about trees, but at least I’ve got your attention. As a consulting arborist, I am most frequently called to a property when trees are looking sick or starting to die. Usually, the trees that present the most problems are young trees that are less than six or seven years in the ground.

The most common cause of failure of young trees is that they were planted too deeply. Instead of the root flare and the major structural roots planted at or just below soil level, I find that they are buried three, four, and even an incredibly deep eight to ten inches below grade! As I dig out the root flare and discover just how deep a tree has been planted, I always explain to the client exactly why trees fail to thrive and eventually die when they are planted too deep. When tree roots are too far below grade, they are deprived of the oxygen which is vital to root metabolism and development. Additionally, the trunk tissue that is exposed to constant moisture in the soil eventually rots, thus destroying the underlying cambium—the vascular system of the tree.

The second most common cause of young tree failure is the destruction of the tender young bark due to string trimmer and lawn mower damage. Again, when I encounter this problem, a lesson in tree physiology follows. When a client is educated in the “why” of a problem, they are then not likely to repeat the same mistake. This makes for an enlightened client when they are the ones responsible for the poor planting and maintenance issues that lead to a tree’s decline or death.

Sadly, I all too often find that the client is NOT the one responsible for these issues. Instead of having a now educated client who knows not to repeat the same mistakes, I’m now dealing with a frustrated and angry client who is asking me why “Company X” didn’t do the job that they were hired to do properly! The client now realizes that they’ve lost valuable time and money on a tree that was either doomed to fail at planting, or was being systematically killed each time a lawn mower or weed trimmer string took a little bit more bark

off the tree—and sometimes it’s the same company that installed the tree and had the maintenance contract! If you are the owner or manager of a landscape company, please don’t assume that your company would “never”

do such poor work. All too often Company X is a big name, well-known company in the industry. They were hired on their reputation or the merits of their fancy advertising because they were trusted to do quality work. Now the client is realizing that the trees are past the warranty period and they are stuck having to pay to have the work done again.

Company X has now lost a client, and is getting very negative publicity amongst all of the client’s friends and co-workers, thus ensuring the loss of future clients as well. And Company X may never really know why they’ve lost the business. As much as I hate to say it, there are several Company Xs who are guilty of the poor work I’ve just described.

The quality of your company and your company’s reputation is only as good as the quality of your personnel. In this economy, every contract counts! If you are not educating and re-educating your personnel yearly and if you are not regularly and carefully inspecting your employee’s work, you may be that Company X. If you are not investing time and energy in keeping quality standards high, there are several other landscape companies that will be more than happy to pick up any clients that you lose.
