decline and die. Be sure to select trees that are well adapted to ouralkaline soils. Check with your county extension office for soil testinginformation (Bannock County 208-236-7310).2Maintenance: All trees need regular watering and periodic inspectionfor pests and disease. Broadleaf trees also need routine pruning.Carefully selecting a tree that is suited to the planting site will savetime and money.TREES AND UTILITIESTree limbs and power lines are not a good combination—especiallywhen storms bring lightning, high winds, and ice. Utility companies trimtree limbs away from power lines to prevent power outages duringsevere weather. To prevent problems, choose utility-friendly trees fromthe “Small Trees” section, or contact cwestling@idahopower.com,208-736-3213/208-221-3128.Underground utility lines can easily be cut with a shovel, and youare legally and financially responsible if you damage them. Idaholaw requires that you call Digline, 1-800-342-1585, before digging.Employees of utility companies will mark locations of undergroundlines at no charge.STREET TREESStreet trees are planted in the area between sidewalk and curb.This area is called the parking strip, and it is under city jurisdiction.Before You Plant

3Pocatello’s tree ordinance requires that tree branches be kept 8’above sidewalks; 12’ above streets; and 14½’ above designatedtruck routes. The ordinance and Master List of Acceptable Treesexplain requirements and prohibitions related to street trees. To seethem, visit Pocatello City Hall or www.Pocatello.us/pr/documents/acceptable_trees.BE FIREWISEFirewise practices include removing dead wood and low treebranches; removing vegetation from roofs, gutters, and under decks;selecting fire-resistant plants; and keeping tree limbs 15’ away fromchimneys, buildings, and power lines. To learn more: www.firewise.orgor Three Rivers RC&D at 208-241-4656.PLANTING INSTRUCTIONSCare For Your TreesThe most common and serious planting error is planting too deep.Before planting, find the root flare—where roots spread at the base ofthe trunk. This flare should be partly visible at the top of the plantinghole.The most common planting stock found at local nurseries are incontainers, bareroot, or balled and burlapped (B&B). Plantingprocedures vary depending on the kind of stock selected. For a sturdytree, carefully follow these procedures:1. Dig hole 2 to 3 times as wide as the root-ball and the same depthas the tree was planted in the nursery. The sides of the hole should berough and uneven to help roots grow into the surrounding soil.Container Stock: Gently remove container and inspect root-ballfor circling roots. If you see only a few, gently separate and spreadthem outward. Eliminate masses of circling roots by making twoto four half-inch deep vertical cuts in the sides of root-ball. Cut ashallow “X” on the bottom of the root-ball. If soil covers the rootflare, brush it off. Place root-ball in planting hole. Make sure topof root flare is level with or slightly higher than surrounding ground.Balled & Burlapped (B&B): If soil covers the root flare, brush it off.Carefully place tree in planting hole so top of root flare is levelwith or slightly higher than surrounding ground. If you need toadjust tree’s position, shift the root-ball; do not twist tree trunk.Straighten tree and add just enough soil to stabilize it. Cut andremove all twine or wire. Remove as much burlap as possible, assome is not biodegradable.

4Care For Your TreesBareroot: Keep roots moist at all times! Remove damaged orbroken roots. Place tree in planting hole at the same depth thatit grew in the nursery. Do not let roots curl up or around hole. Holdtree straight while filling hole with soil. With your hands, gentlypush soil under and between roots to remove air pockets. If treesettles too deeply, gently pull it back to the proper depth.2. Stand back and inspect the tree from several sides to make sure it’sstraight. If it is not, adjust it. Add soil around roots until hole is half full.Lightly water to settle soil and remove air pockets. Gently tamp soil tocompress it around root-ball, taking care not to damage any roots.Add soil until hole is filled. Do not cover top of root flare with soil.3. Make a shallow basin to hold water around the roots. Fill the basinwith water several times, allowing it to soak into the root-ball betweeneach filling. Add soil where excessive settling occurs.4. Fill the basin with 2–3” of wood chips. Do not place wood chipsdirectly against the tree trunk, as this may promote trunk rot.5. Remove dead, broken, or crossing branches.6. Unless the site is windy, it is not necessary to stake the tree. Do stakeif the root-ball is fractured or the trunk is not stable. Remove stakesafter one year.HOW TO PLANT A TREE2/3 distance fromroot collar flare tofirst branchStakeIf necessary, stake the treewith wide, flat straps andattachments that allow itto move a little in thewind.Backfilled soilRoot collar flareDo not plant treelower than this.2 - 4 inches mulch2 - 5 times width of root ball

6Care For Your TreesOverfertilization can also contaminate groundwater or pollute nearbybodies of water. When applying nitrogen, choose slow-releaseformulas to reduce the chance of root burning, which some quickrelease,high-concentrate nitrogen fertilizers can cause. Naturalorganic forms of nitrogen are the best choices.Pruning improves structure and enhances vigor of mature or agingtrees. Dead, broken, or crossing branches should be pruned fromtrees of any age. Cut branches just outside the branch collar. Avoidmaking flush or stub cuts. Wound dressings are not necessary and mayimpede the tree’s natural healing process. For more information, or fora list of certified arborists, contact the city forester at 234-1895.PROPER PRUNING PRINCIPLESPests are insects, mites, bacteria, fungi, and viruses. Many organisms inthe landscape are considered pests because of the damage they door because their numbers are so large. Some of these organisms donot harm plants but are in fact beneficial to them and are a valuablepart of the ecosystem.Many pest problems result from improper watering, poor plant stock,or an inferior planting site. Trees that are poorly adapted to a site areusually most affected by pests. Choosing a tree that is well adaptedto the site will significantly reduce many pest problems.In selecting trees for this guide, we have chosen species that haveadapted well to our local environment. We have identified pestsassociated with some of these trees, but with proper attention tocorrect planting procedures, growing conditions, and maintenance,you will promote a tree’s best protection against pests: good health.

7Weeds and Herbicides do not belong near trees. To keep areasaround trees free of weeds and other competing plants, use woodchip mulch to suppress them, and remove them by hand whenpossible. Avoid using herbicides near trees as some formulationsseriously injure or kill them. If you do use them, avoid getting any onleaves, branches, trunks, or near roots of any plants you wish to keep.Some fertilizers contain weed killers; these weed-and-feed fertilizersshould not be used near tree roots. Remember that a tree’s rootsextend well beyond its outermost branches.TREE GUIDE LEGENDLIGHT REQUIREMENTFull Sun Part Sun ShadeTREE SIZES AND FORMSHeight, width, and other characteristics are provided for specifictrees in the Recommended Trees section of this guide. The tree formspictured here are examples of crown shapes of mature trees. Seeinghow a tree will look will help you plan its inclusion in your landscape.Tree descriptions in this guide refer to these forms.spreading columnar vase pyramidalTree Guide Legendoval rounded irregular multistemHARDINESS ZONESUSDA Hardiness Zones are based on minimum winter temperatureranges throughout the U.S. A zone rating can help you select a treethat is cold hardy in your zone, but keep in mind that a cold-hardytree may not tolerate other conditions (soil, wind, low rainfall) in ourarea. Other cautions: different growers may assign different hardinesszones to the same species; groups other than the USDA have createdtheir own zone classifications, and their zone numbers do not meanthe same thing as the USDA’s.

Most of Pocatello falls into USDA Zone 5, with minimum temperatureranges of -20 to -20F. Contact your local extension office to find outyour area’s hardiness zone. A green ‘Z’ followed by the zone range isgiven for each tree in the tree selection section.AVAILABILITYLocal nurseries sell some of the trees recommended in this guide, butsome of the best trees for this area may have to be special ordered.When you place a special order, it may help you to know:• Almost all trees sold here are grown fairly far away. It is usuallynecessary to get your special order tree placed with a shipmentthat is already coming in or shipping expenses would be very high.• Just because growers have a certain tree in their catalogs doesnot mean that tree is always available. Tree availability is usuallybest in the fall and worst from April through July. The best time toorder your special tree is in the fall for next spring.• If you want a special order of a bareroot tree, be aware thatmost bareroot trees must be ordered in bundles. The nursery maynot want to order a bundle of 5 or 10 trees if you only want one.• When ordering special trees, don’t give up if they are not instantlyavailable. Give the retail nursery advance notice and plenty oftime. If you want a special tree you probably already know it’s agreat tree, so don’t settle for a lesser substitute too quickly.Designations for availability of tree selections:readily = commonly availablerequest = nursery can special ordermail order = rarely available from nursery but available onlineseedling only = generally mail order as seedlings only8ORIGINNative to southeast Idaho and nearby regionsTree Guide Legend

GRAFTED CONIFER VARIETIESGrafted trees are more uniform and predictable than seed-growntrees, which can differ in size, shape, and growth rate even amongtrees from the same seed batch. Yet most conifers are seed grownbecause grafting them is difficult, time consuming, and expensive.Grafted conifers cost two to three times more than seed-grown trees,but the advantages of grafted conifers may be worth their extra cost.Buying the right variety of a grafted conifer allows you to reliablyselect specific traits. You can choose a blue spruce that is deep blueand tall but narrow in form. Or you can pick one that only grows to15’—not the 70’ that a seed-grown spruce might reach. Consider thisscenario: you buy a $50 seed-grown blue spruce instead of a smaller$100 grafted spruce. In 20 years, paying for removal of the overgrowntree can cost up to $1,000.Hundreds of varieties of grafted conifers will grow well here. They growin every imaginable shape, size, and sometimes color, and many canbe ordered through local nurseries. You may find a grafted evergreento be better suited to your particular needs than a seed-grown tree.60MEDIUM CONIFERSCedar of Lebanon, Hardy, Cedrus libani var. stenocoma:Pyramidal-columnar crown with stiff horizontal branching.
