Windbreak Considerations

Tree Species Selection

  • Soils (suitability of your soils to the tree species you want to plant)
  • Hydrology (limitation of tree species in wet areas)
  • Location (proximity to buildings, roads, overhead wires, etc.)
  • Purpose (shelter, wildlife, snow catch, aesthetics)

  • Selecting the Right Tree

    Trees provide many benefits. They can block the wind, help clean the air, provide fruit and nuts, and create a hospitable habitat for wildlife. And, trees make a great hideaway where children can play. Once you decide to add a tree to your backyard, do you know how to select the right tree—one that will live a long time?

    When looking for that perfect tree for your yard, pick one with good form. Most trees should have one main leader (trunk) and a balanced number of side branches. They should look healthy and free from insect damage--and show evidence of growth. Be sure to get your tree from a reputable nursery that has inspected and certified stock. Select a tree grown in your area because trees raised under local growing conditions are more likely to thrive in your yard.

    Container grown trees spend at least part of their life in a pot. These trees transplant well from early spring into fall. Be sure the tree is not simply potted bare rootstock. The root mass will come out of the pot intact if it is a container-grown tree. There should be plenty of feeder roots--those thin, hair-like roots--but not so many roots that the tree has become pot-bound. Also, check the roots for damage. Rodent damage is easy to spot—you will see evidence of chewing and, possibly, tunnels or holes. Avoid any tree with a rotten odor coming from the root area—it probably is suffering from disease.

    Balled and burlapped trees usually transplant well. The tree’s root system is contained within the ball of soil; the soil remains firm around the root system to minimize transplant shock. You do not want a tree that has been allowed to dry out. Make sure your tree’s root ball is kept moist prior to planting.

    Bare root trees are usually extremely small plants. Most of these trees are best planted in early spring before the leaves come out. The roots are exposed, so the trees must be stored in a cool, humid place, and the roots kept covered with a moist material until planting time.

    Knowing what to look for when tree shopping will help you select the right tree. A healthy tree will last a long time and provide many backyard benefits.

    Land Preparation
    12 or 14 ft Spacing Between Rows
    • Planning ahead (sod areas should be broke and worked thoroughly by July 1 of the year prior to planting new trees.)
    • All crop residue should be worked in the fall, and site should be as free of trash as possible
    • Herbicide carryover (potential effects will need to be determined)
    • Tillage (site will be tilled and weed free at planting) 12” to 24” deep tillage.
    • Tree rows must be tilled 8’ wide if weed barrier is to be installed
    • Other (consider the use of pre-emerge chemicals for weed control)

    Care After Planting

    • Landowner must heel in trees after planting is completed
    • Landowner must level any furrows left by tree planting equipment prior to installation of fabric
    • Landowner should drive edges of fabric weed barrier to seal edges into soil
    • Landowner must maintain barrier so it does not girdle the trees or blow off the site

    Tree Care/Weed Control Options

    Seedlings planted with Fabric Weed Barrier

  • Fabric Weed Barrier (fabric material placed around trees that prevents weed growth)
  • Tillage (keeping the area around and between trees weed free)
  • Chemical (there are a limited number labeled for trees)
  • Mowing (this is not weed control and requires a desirable grass species to be planted between the rows)
  • Replacements

    Any tree or shrub that fails needs to be replaced during the first three years to minimize size variation within the planting.

    Any tree or shrub that fails in following years should be replaced to maintain at least an 85% survival of the tree/shrub planting.

    In Row Care

    Fabric in tree belts that are older than 4 years should be inspected to check for injury and how much space is available for the trees to grow in diameter. If the space is not there, the openings should be manually enlarged around each tree. Work, yes, but the effort may save your trees.

    Enlarging the openings may not be easy; you may need to devise a method to cut the fabric away from the trees. An example is to secure a sharp utility knife at the end of a wooden handle that is long enough to reach below tree branches. The blade should be bolted to the end of the handle to give it enough strength to stand up under heavy use. Bolt the knife in place with a slight crook so the position of the knife blade is in alignment with the axis of the stick. This will help avoid the handle twisting in your hands while you are enlarging the opening. Another important consideration is the knife’s capability to either change the blade or sharpen it, as the blade becomes dull very quickly.

    Openings shall be X-,C-,L-, or J-shaped. Length of slit should not exceed 12 inches. Do not use straight slits as abrasion of tree bark can occur.

    It is recommended that you do not let another year go by without enlarging the openings in your fabric weed barrier. Just as our buildings need to be maintained, so does your shelterbelt.
