2018 TV Tree Selection Guide

2 HOW TO USE THE GUIDE The TV Tree Selection Guide is divided into sections determined by the width, height and spacing requirements that trees will need at maturity. Broadleaf trees, that normally shed their leaves annually, are arranged into classes: I, II, and III for easy reference. Conifers, most evergreen, are listed in alphabetical order.

Class I Small trees which do not generally reach over 25-30’ in height and width. Spacing, 20-30’between trees. Good for under power lines or smaller planting areas.

Class II Usually considered medium sized trees mostly planted for their shade and excellent use in the landscape and parkway plantings. Reaching 30-40+’ height and width. Spacing, 30-40’ between trees.

Class III Man y are long lived and attain large height and trunk diameter. Make sure you have ample room to accommodate it at maturity. May reach 70’+ in height and width. Spacing, 40-60’ between trees.

Conifers Pro vide year round greenery, screening and serve as excellent wildlife shelters. Generally, they should not be pruned and will need large growing areas away from buildings, sidewalks and driveways. Spacing varies with species.

TREE FORMS Columnar, Irregular, Oval, Pyramidal, Rounded, Vase and Weeping are shown beside the form designation. A search on-line will show the forms mentioned.

4 USDA ZONES The United States Department of Agriculture (USDA)has established ten hardiness zones (temperature ranges) throughout the United States based on 10 differences in the average annual minimum temperature. Trees are propagated and grown to match these zones. Referring to these zones can help you decide which type of tree to plant for optimal growing success. The four hardiness zones in Idaho are listed below with the average annual minimum temperature for each:

Zone 3: -40 to -30 F Zone 4: -39 to -20 F Zone 5: -20 to -10 F Zone 6: -10 to 0 F

These zones are in parenthesis under the “Growing Conditions” section of each page. The Boise area is zone 5/6. Contact your local extension office for the correct zone in your area. TREE REMOVAL/PLANTING PERMIT Some cities require a permit to remove and/or plant a tree in the public rights-of-way, from the road edge to the private property line. Some streets have parkways of varying width in which trees, grass or low ground cover are planted also called planting strips. These parkways or planting strips are generally in the public rights-of-way and may need a permit to remove and/or plant a tree. PLAN BEFORE YOU PLANT The importance of matching the tree and its growth requirements to the planting site cannot be over emphasized. The best planting plan will not save a tree that is poorly suited to the planting site. The tree must be able to tolerate factors such as unfavorable soil conditions, inadequate or excessive water levels, space and shade limitations. Selecting a tree that meets the site conditions is the single most important factor in achieving its success. When planting more than one tree be conscious of the different planting space requirements for each species (this is found next to “size” on each illustrated page). In Idaho you must call Digline at 811 or 208-342-1585 before digging.

To select the planting site and the tree that best fits your needs, carefully consider:

A Landscaping purpose – To provide shade, color, a screen from the wind or to enhance wildlife habitat.

B Planting site – Are overhead or underground utilities present? Make sure you give your tree adequate room to grow. Try to envision it 10-50 years into the future. How close is the tree to structures and other trees near the planting area.

C Soils – In urban areas can be highly variable. Too much or too little drainage often causes trees to decline and die. Check with your county extension office on ways to test your site's soil condition.

D Maintenance – All trees need regular watering, routine pruning and periodic inspection for pests and disease. Planning now can save time and money later.

5 TREE PLANTING INSTRUCTIONS The three most common types of planting stock found at local nurseries are in containers, bare root, or balled and burlapped (B&B). Planting procedures will vary depending on the type of stock selected. Each has advantages and disadvantages, but a sturdy tree will result by carefully following the procedures outlined below. 1. Dig a hole 2-3 times as wide as the root ball and the same depth as the tree was planted in the nursery. Make sure the sides of the hole are rough and uneven. This helps the roots become established in the native soil. Continue with the steps below, depending on the type of stock you are planting.

TYPE PLANTING PROCEDURES Container Stock Gently remove container and inspect the root ball for circling roots. If only a few are found, gently separate and spread them outward. Eliminate masses of circling roots by cutting 2-4 vertical slices on the root ball sides to a depth of one-half inch and cut a shallow "X" on the bottom of the root ball. Cutting circling roots in this way allows growth of new roots into the surrounding native soil. Place the root ball in the planting hole, making sure that the top is level with or slightly higher than the surrounding ground.

Balled & Burlapped Carefully set the tree into the planting hole so the top of the root ball is level with or slightly (B & B) higher than the surrounding ground. If the tree is in a wire basket, completely remove it, if possible, or remove the upper one-half after the tree is in its final planting position. Take care not to damage the roots or disturb the integrity of the root ball. Adjust the position using pressure on the root ball; don't move it by twisting the trunk. Straighten the tree and stabilize it by adding soil around the bottom portion of the root ball. Cut and remove all twine, and cut the burlap half way down the root ball.

Bare Root Be sure to keep the roots moist at all times! Prune away any damaged or broken roots. Place the tree in the hole at the same depth that it grew in the nursery. Do not allow roots to curl up or around in the hole. Add soil until the tree can stand by itself. Hold it straight while the hole is being filled. Gently push soil under and between roots with your hands to remove large air pockets. If the tree settles in the hole, gently pull it back to the proper depth.

2. Stand back and inspect the tree from several sides to make sure it's straight. If not, move the tree in the hole until it stands straight. Backfill with soil around the roots until the hole is half full. Water sparingly to settle the soil and remove air pockets. Lightly tamp the soil in with the shovel handle to compress the soil around the root ball, taking care not to damage the roots. Continue adding soil until the hole is filled.Do not cover the top of the root ball with soil. 3. With the remaining soil, build a basin around the edge of the filled hole. Fill the basin with water several times and allow it to soak into the root ball between each filling. Add soil where excessive settling has occurred. 4. Fill the basin with 2-3" of wood chips. Do not place chips directly against the trunk, as this may promote trunk rot. 5. Unless you live in a windy area, it is not necessary to stake the tree. If you do stake, remove them after one year. Stake if the root ball is fractured or the trunk is not stable.

6 MAINTAINING HEALTHY TREES Once a tree is planted there are several things that must be done to help ensure its survival. Most of the threats to the health and life of young trees can be avoided or reduced with a few simple precautions. Please read the following post-planting care tips carefully. WATERING Watering the tree regularly during the first year is critical to its establishment. Apply about 1 ½" of water per week at one time, rather than watering daily. Place a shallow pie pan under the tree canopy and water the area until 1½" accumulates in the pan. Depending on your sprinkler system, it may take ½ hour to 3-4 hours. Begin watering in the Spring when soils start drying out and continue until Fall. Deduct rainfall received during the week from the 1½" total. Water more often in periods of drought and above normal temperatures. prune broken or dead branches MULCHING Mulching is a must! Mulch with wood chips to help retain soil moisture and stake only reduce weeds. It also protects the tree from lawn mowers and weed whippers. when absolutely Mulch with 2"-3" of material at a 6' diameter. Keep mulch away from the tree necessary remove after trunk a few inches to avoid trunk rot. As mulch decomposes, it enriches the soil 1 year and provides organic matter and beneficial micro­organisms. remove transit FERTILIZING trunk guard Fertilizers are natural or synthetically produced elements applied to 2" to 3" mulch of bark or wood chips the soil or foliage of plants to supply nutrients necessary for normal or accelerated growth. With the exception of nitrogen, fertilizing with other nutrients is usually not required unless a known deficiency exists. As long as your trees have normal leaf size and color and appear to be growing keep mulch away from root collar well, the nutrients in the soil are probably adequate. wider hole If a deficiency is suspected, a soil analysis should be done to determine if soil is what nutrient or mineral is deficient. Testing can usually be performed compacted by an agricultural soils laboratory or by your local county extension remove burlap service. After testing, a report is prepared for you identifying what and wire basket nutrients need to be applied to correct any deficiencies. Only those rootball in undisturbed soil nutrients which are known to be deficient should be applied since over application of certain elements over time can be harmful to your trees. Over fertilization can contribute to ground water contamination or pollution of adjacent bodies of water. If nitrogen is to be applied, slow release formulas are recommended as they will limit the chances of root 'burning', which can be caused by some of the quick release, high concentrate, nitrogen fertilizers. Natural organic forms of nitrogen are your best choices for fertilizing. PRUNING Pruning is the most common tree maintenance procedure. Pruning to improve structure or enhance vigor is associated with mature or aging trees. When planting young trees, prune to remove the dead, broken or crossing branches. Cut the branches to just outside the branch collar. Avoid flush cuts or stubs. Do not apply wound dressings to the cut area after pruning. It is not necessary and may impede the tree's natural healing process. For pruning assistance, contact your local city Forestry Department for a list of recommended Licensed Tree Services. PESTS Some of the more common forms of pests include insects, mites, bacteria, fungi and viruses. There are many organisms in the landscape that are considered pests because of the amount of damage they cause the host plant or because they may be present in such large numbers that they become undesirable. However, some of these organisms do not harm plants but are truly beneficial to the host plant and are a valuable component of the ecosystem. Many pest problems occur as a result of improper watering, poor plant stock, or an inferior planting site. Trees that are poorly adapted to a particular site are usually the ones most affected by pests. Choosing the appropriate tree and planting it in an environment capable of sustaining good growth will significantly reduce many pest problems. In selecting the trees for the illustrated section of this guide, we have chosen species that have adapted well to our local environment. Although we have listed certain pests associated with these trees, with the proper attention to correct planting procedures, growing conditions and maintenance, you will promote a tree's best protection against pests ... good health. WEEDS AND THE USE OF HERBICIDES Keep the area around your tree free of weeds and other competing plants. Use wood chip mulch to suppress the weeds or remove them by hand when possible. Avoid the use of herbicides near the tree as certain formulations may seriously injure or kill the tree. If you decide to use herbicides, avoid getting any on the leaves, branches, trunk or near the root area of any plant you wish to keep. Beware of fertilizers containing weed killers. These types of 'weed and feed' fertilizers should not be used over areas where tree roots are growing, as they can seriously injure or even kill trees. Remember that tree roots extend well beyond the perimeter of the outermost branches.
