Planting Guidelines
Many factors must be considered in planning tree plantings, regardless of whetherthey are located in the mountians or plains, or whether they have been designed tobenefit wildlife, control wind, or to be used for landscaping purposes. These factorsinclude: location, elevation, soil type and alkalinity, prevailing wind direction, weedcontrol, watering needs and availability, snow drifting, power lines, planting size, speciesselection, and site preparation. Spring and fall are the best seasons to plant trees.
Select the location - Choose a spot where the tree can reach its full size; note height andspread the species is expected to reach at maturity. Keep trees back from buildings andfrom beneath utility lines.
Dig a wide planting hole - The planting hole should be dug only as deep as the rootballand at least twice as wide. Rough up soils on the sides of the hole to facilitate a goodbond with the rootball soil and aid root movement. Begin filling the hole with theoriginal soil that was removed until it is about one-third full, then gently pack the soilaround the base of the root ball. Continue back-filling the hole by adding a few inchesof soil at a time, followed by water to eliminate drying air pockets, until the hole is filledto its original growing level. This level is indicated by a dark stain on the trunk, whichmarks the difference between root and trunk bark. Do not use your feet to tamp aroundthe tree base as this compacts the soil and may inhibit the spread of roots. Rake a ridgeof soil two to four inches high aroung the margin of the hole (outside the root area) toserve as a reservoir when watering.
Stake the tree, if necessary - Staking a tree can cause bark damage and reduces thedevelopment of strong roots and a tapered trunk. However, trees should be staked toavoid shifting during high winds. Stake very carefully with a broad, soft strappingmaterial such as woven belt fabric. Drive one to three stakes into the ground just outsidethe perimeter of the rootball and into undisturbed soil, spacing them an equal distanceapart.
Chapter 4 - Planting Guides Page 32
Staking the Tree (continued)Attach one end of the strapping material to the tree at the lowest practical level to
maintain the tree upright. Fasten the other end to the stake while still leaving enoughslack to allow for wind sway. Remove the staking material after the first year of growth.
Mulch the Base of the Tree - A two to three inch layer of mulch conserves soil moistureand protects newly planted tree roots from hot and cold temperatures, and also keepsweeds out. Keep mulch at least two inches away from the base of the trunk to reducefungal growth and wood rot. Maintain a mulched, grass-free area around your tree (forits life) to reduce competition for water and nutrients and to protect the trunk from lawn-mower/trimmer damage.
Mulch Wide, Not Deep

Watering
Proper watering is the most important factor in keeping your plants growingvigorously. Watering needs vary with individual plant requirements, as well as the soiltype, drainage, exposure and weather. Develop a watering schedule from your ownexperience by checking the soil moisture. You can do this by digging down about 6inches just outside the root zone. If the soil tends to crumble when you squeeze it, youshould water the plant. If the soil forms a ball, wait a few more days before watering.Do not worry about the dryness of the top inch of soil. Plant roots need both air andwater for development. If you water too frequently, you keep the soil constantly wet andexclude oxygen from the roots. Therefore, when you do water, soak the ground thoroughlyenough to saturate the root zone, but allow adequate time between waterings to permitthe soil to drain and air to penetrate into the root zone. Watering trees at the drip line oftree branches and beyond is recommended; this will ensure that soil moisture is therefor the greatest majority of the roots.
To assure survival, a tree will need 10 gallons of water per inch of trunk diameterwith each watering. A typical garden hose on medium pressure will supply 10 gallons in5 minutes of run time. The way to calculate how long to leave water running forappropriate water application is to take the diameter of a tree times the five minutesneeded to get 10 gallons of water flow. Therefore, 8-inch diameter trees will need 40minutes of water flow to receive 80 gallons of water. Most trees will need three wateringsper month from April through October. Newly planted trees and shrubs need additional,supplemental water applications during their first growing season. Due to our dry climate,the supplemental water must be applied to even low-water-requiring plants until theroot system is developed and well established.
Chapter 5 - Tree Care Page 36
Winter Care
�Hardened� or preconditioned plants can withstand remarkably low temperatures.Practices that aid in hardening trees to cold include: a. Avoid early fall overwatering. Reduce watering after August 15 - Sept.1. Excesswater in late summer stimulates new tissue growth, which is sensitive to cold. Remember,however, that late fall watering, after trees are hardened, is beneficial. b. Avoid late summer fertilization. High nitrogen and calcium fertilization, inparticular, promotes new growth and increases sensitivity to injury. However, fertilizationafter leaf drop is a good practice. c. Avoid late season pruning. This stimulates tissue growth and hinders planthardening.
In this area, most winter damage is caused by drying out of plant tissues. Thecombination of winds, intense sunlight, and sparse winter moisture causes stress toplants, especially young plants with small root systems. Typically, in Wyoming, therecommendation for winter watering is to apply water when the daily temperatures exceed45 degrees and the ground is not frozen. If possible, watering once a month from Octoberthrough April will supply plenty of water to sustain trees.
Fertilizing
It is best not to use fertilzer the first year. (Never apply high nitrogen fertilizer atplanting time as it may burn tender roots.) Good, rich native soil, placed in the hole, isusually adequate. Tree fertilization is often overrated as a cure-all and is also oftenignored when it could be helpful. Fertilizer application can help plants grow better,withstand various stresses, and reduce winter damage ONLY if the elements applied arelacking in the soil. Gradual reduction in annual growth is often a sign of low soil nutrients.
Chapter 5 - Tree Care Page 37
Fertilizing (continued)Trees and shrubs make most of their growth in spring and early summer. Apply
fertilizer long enough ahead of this growth period so it will be available in the soil oreven stored inside the plant. Regardless of when fertilizer is applied, it may not bereadily absorbed or utilized until growth begins in the late winter/early spring. Uptakeand metabolic demand are low in the dormant season, and some of the more solubleforms of nitrogen may leach from the soil before they can be utilized. Studies show thatnitrogen uptake peaks during the spring and summer when metabolic need is greatest.Late summer or early fall fertilization can force the production of new growth that doesnot have time to mature and become hardy before severe winter cold. Fertilizer uptakeis greatest during periods of active root growth, so applications of fast-release fertilizersare most effective spring through fall. Slow-release fertilizers can be applied at anytime the ground is not frozen and when soil moisture is adequate.
PruningPruning should be done with a purpose and not as an automatic routine. Prune only
dead or broken branches the first year. Begin corrective pruning only after a full seasonof growth in the new location. In the second growing season, begin training by removingcrossing limbs and selecting permanent branches evenly distributed along and aroundthe main trunk. For the first 1 to 5 years, leave small temporary branches, especially onthe lower trunk, to help the tree develop taper and promote early rapid growth. Eachyear remove a portion of these temporary branches. As trees grow to maturity, the needfor structural pruning should decrease and pruning should then focus on maintianing thetree�s structure, form, health and appearance.
Proper pruning cuts are made at the point where one branch to twig attaches toanother. The cut is made just outside the branch bark ridge and collar. Flush cuts andstubs should be avoided. Remove a large limb by making three cuts, (See page 41)which will reduce chances of injury and damage to the tree. On small branches, make asharp and slightly slanted, clean cut just beyond a lateral bud or other branch. Pruningcuts should be clean and smooth, leaving the bark at the edge of the cut firmly attachedto the wood. The best time to prune living branches is in late dormant season or veryearly spring before leaves begin to open. Dead and injured branches can be prunedanytime.

Weed Control
Weed control is an extremely important factor for tree growth and survival. Weedsare better competitors than seedlings, for moisture, nutrients, and sunlight. They alsoprovide fuel for fires and habitat for tree-injuring pests. Mulch, cultivation, and herbicidesare three basic methods for controlling weeds. Herbicides must be used with care andshould be selected specifically for the weed type, soil, and species. Read the herbicidelabel carefully.
Cultivation around trees and between tree rows controls competitive weeds, improvesmoisture conditions, reduces fire hazards, and decreases the need for supplementalwatering.
Mulches have significantly improved the survival of tree plantings. Mulch reducescompetition from weeds. Woven plastic mulches are woven in a pattern that allowsmoisture to pass through to the soil but minimizes evaporation. Organic mulches suchas wood chips or bark can also be used. Straw and hay mulches tend to attract rodentsthat can damage trees.
For large plantings, a tractor drawn woven mulch applicator is available for usethrough the Washakie County Conservation District. The applicator lays the mulchright over the freshly planted seedlings where the trees are later pulled through openingscut in the mulch.
Wind and Sun Protection
Most Wyoming evergreen plantings require protection from wind and sun, particularlyduring the winter months. Sunlight reflected off snow, while soils are frozen, can quicklydry unprotected conifer foliage. Young trees are more susceptible to this kind of damage.Shading seedlings and blocking wind from the south and west is critical and can beprovided using a number of items. Existing vegetation, rocks or logs are the easiest andcheapest to use, while shake shingles and commercially manufactured shade productsare also available.
Chapter 5 - Tree Care Page 40
Keys To Proper Pruning
� Pruning cuts must be made outside the branch bark ridge and the branch collar.� Cuts made too close, also called flush cuts, do not heal correctly.� Cuts that leave stubs, often start the decay process which will weaken the branch.� When shortening small branches, make cuts at lateral buds or other lateral branches.� When removing a large limb, the 3-cut method should be used to prevent tearing.� Under no circumstances should more than 1/3 of the foilage be removed at any onetime, on young trees. On mature trees, no more than 1/4 of the foilage should be removedwithin a growning season.� Do not top trees! Topping is the drastic removal of the upper portions of the tree.Branches are cut back to stubs, giving the tree an ugly and deformed appearance. Aftertopping, the tree puts on a flush of new growth that is much weaker and prone to breakageand dieback.
Branch Pruning
Cut living and dying branches(A) as close as possible tothe branch collar (B).
-Do not remove the branch collar (C).-Do not leave stubs (D).-Do not paint the cuts.
If possible, avoid pruningwhen leaves are forming or falling.

Animal Protection
It is essential to protect trees and shrubs from livestock of all types. Livestock willkill or damage trees and shrubs at all stages of their life cycle. Damages include: eatingor trampling seedlings, damaging mature trees by rubbing off bark, or breaking andeating branches and foilage. Deer, elk and rodents can also destroy plantings in a shortamount of time. Fencing is the most effective method to minimize this damage, andwhile fencing is expensive, the development of electric systems has decreased costsover traditional wire. Using individual plastic seedling protectors can also minimizeanimal damage.
Many commercial repellents can also be used to protect plantings from animaldamage. The effectiveness of commercial brands varies and often is dependent onrepeated application. An effective home remedy is to mix whole eggs with tap water toform a 1:5 solution of eggs to water, strain the solution and spray on the seedlings.Another method, which has been used effectively to eliminate pocket gopher problems,is to place a half stick of chewing gum into the animal�s burrow.
Insects and Disease
Insects normally do not cause much damage to healthy trees. When trees are growingslowly or lacking vigor because of drought or trampling by livestock, insect attacks maythen become serious. The most common insects which attack trees and shrubs are:aphids, western tent caterpillars, bagworms, sawflies, tree borers, grasshoppers, spidermites, scale insects, elm leafbeetles, fall webworms and tip and shoot insects.
The most common diseases include: canker diseases, decay and rot fungi and foliardiseases.
Technical assistance in identifying and treating insect and disease problems is listedon page 49 of this pamphlet.
Chapter 5 - Tree Care Page 42
Conservation Trees
Conservation trees include plantings for windbreaks to protect farmsteads, livestock,and crops. Windbreaks can be designed to trap snow, wildlife habitat, firewood, erosioncontrol, buffer strips, energy savings, livestock protection, and a host of other uses.Farmstead windbreaks significantly reduce the wind speed around buildings and canresult in energy savings of up to 40 percent, which creates a comfortable environment tolive and work. When planning a conservation planting, there are many variables toconsider:
� The purpose of the planting (i.e. farmstead windbreak, wildlife habitat, etc.)� The hardiness zone (or climate, precipitation, and elevation of the area to be planted) -these zones are shown on page 35 of this publication.� The water requirements of the species as a mature tree, and the availability of water tosustain the tree.� Soils and site characteristics - species need to be adapted to your soil characteristics(texture, pH, and salinity), to the specific site characteristics (depth to water table orbedrock), and other limiting criteria.� Diversity - diversifying the species used in your plantings may reduce the effects ofinsect or disease infestations to your planting.� Location - overhead or underground utilities, distance from protected area, snow driftingeffects, location of septic systems, and proximity to roads (do not create blind corners).� Special plantings like windbreaks and living snow fences require specific design criteriain order to maximize effectiveness and growth potential. These criteria include: spacingbetween trees and tree rows, row length, tree density, species height arrangement, andsnow trapping distances.
Technical assistance for help with species selection and windbreak design are providedby the Washakie County Conservation District and the Natural Resources ConservationService.

Community Forestry
Community Forestry is defined as the planting and management of trees to maximizethe benefits to communities. Trees in Wyoming naturally grow in the mountains andalong waterways. However, when planting trees around our property, we need to knowabout the species we�re planting, such as height, placement, and how they can be usedfor many benefits. Strategically planted trees around your home can create a beautifullandscape while also providing energy savings all year round. Deciduous trees that shedleaves in the fall can provide shade to cool a home in the summer, while allowing sunlightand its warmth into the interior of the home in winter. Well-placed conifers and otherevergreen trees and shrubs can deflect or block winter�s harshest winds.
Cooling
Trees can shade a home�s windows and walls from the hot summer sun. They willalso create a cooler atmosphere around the home, cooling sidewalks and driveways thatnormally reflect heat. They are able to do this through a transpiration process that coolsthe air around them, acting as nature�s evaporative coolers. Cooling costs can besignificantly reduced by shading. Shading an air conditioner will also improve it�sefficiency by up to 10 percent. Below are some tips when planting trees and shrubsaround your home:� Medium to large trees provide excellent cooling because they shade both home andyard, helping to cool the outside and inside temperatures. However, do not plant largetrees near power lines.� Plant deciduous trees on the east and west sides of the home to offer the greatestenergy savings by blocking the morning and afternoon sun, while offering no obstructionto winter sunlight.� Shrubs and small trees can be planted to shade air conditioners and heat pumps.However, be careful not to plant too close to the unit, blocking its air flow. Keep unitsfree of leaves and needles.� Incorporate eaves into the home�s structure on the south side for cooling.
Chapter 7 - Community Forestry Page 44
Heating
Properly placed trees and shrubs can help reduce heating costs by blocking winterwinds. In addition, deciduous trees planted to cool a home, will lose their leaves in thewinter and allow the radiant heat of the winter sun to warm a home�s interior.
� Conserve energy by planting a combination of evergreen trees and shrubs on the sideof your home that blocks the coldest of winter winds. Choose vegetation with brancheslow to the ground.
� When siting a new home, consider free passive solar heating. -Orient the home so the broadest area and the most windows face south.
� On sunny winter days, open drapes to allow the low-angled winter sunlight to heat theinterior of the home.
Remember, trees are relatively small at planting time but can reach heights of 80feet and can be just as wide depending on the species. When purchasing a tree, checkthe tag for the mature height and spread of the tree.
Tree Species Selection
When selecting a tree to plant, it is critical to choose a species that will thrive in yourcommunity.
Hardiness Zone - Washakie County is located in Hardiness Zone 4. Tree and shrubspecies with a Hardiness Zone 4, or lower, are recommended. (See page 35.)
Moisture - All trees and shrubs need moisture to survive, but some species are moredrought tolerant than others. On sites where moisture is limited, trees with higher droughttolerance are recommended.
Other factors to consider in selecting a tree species is tolerance to a wide range ofsoil conditions and resistance to insects and disease.
Chapter 7 - Community Forestry Page 45
Acquiring a Quality Tree
Quality trees and shrubs can sometimes be difficult to find in Wyoming. The purchasermust be able to identify quality nursery stock. Desirable and undesirable characteristicsto look for include:
� Size - Trees should have the dimensions common to their species, diameter and age.The root ball diameter of balled and burlapped trees should be 1 foot for each 1 inch oftrunk diameter.
� Form - Trees should be typical to their species. Tree trunks should be relatively straightand have adequate trunk taper and diameter in relation to their height. The crown shouldbe well-formed with one main stem and branches should not have tight crotches.
� Vigor - Trees should have well-developed branches that are less than half the diameterof the trunk and are evenly distributed along the trunk. Leaves should be of normalcolor and not shriveled. If trees are dormant, without leaves, check the number andlocation of viable buds. Buds, bark, and branches should not be shriveled, desiccated,or discolored.
� Roots - For balled and burlapped trees, the soil ball should be held together tightly andfeel damp to the touch. If the ball is broken or loose, many of the roots, especially thesmaller feeder roots, have probably been injured. If the trunk can be easily moved fromside to side, the roots have likely been damaged. To check for circling roots, which canstrangle a young tree, pull back the burlap or remove the pot and inspect the roots.Circling roots should be cut to prevent future damage to the tree. The roots of bare roottrees must be kept moist at all times. Check roots to make sure they are not dry and areadequately protected against drying.
� Wounds - The trunk and branches should not have any injuries including excessivepruning wounds, broken limbs, sunscald, discolored bark, rot or insect and diseasedamage.
