The Cooperative Extension Service at Kansas State University recommends several tips for planting trees. Pamphlets listing the recommendations are available though the Douglas County Extension Service, 2110 Harper, and include the following:
Select trees that are adapted to your area. Most nurseries will have charts outlining whether a species is likely to survive in your area.
Soil textures should be considered. Transplanting trees from nurseries often can be difficult in tough, clay soils. Prepare the existing soil by digging a large planting hole, breaking up the large dirt clods and spreading the roots carefully when setting the new tree.
Remove burlap bags, wire, plastic and planter pots before planting the new tree.
A mound of dirt in the center of the hole helps naturally spread the tree's roots.
Plant the tree at the same depth it had been in the nursery.
After planting, build up a berm about 3 or 4 inches high around the planting hole to aid watering and prevent runoff.
In an average soil, trees should be soaked once a week if there is less than an inch of rainfall. Water more often in sandy soil, less in heavy or clay soil.
Not all transplants need pruning, but owners should understand the tree species and its particular branching structure. Preserve the natural form of the tree.
Staking may be necessary to prevent the tree from wind damage. Tie the tree to stakes so that the top of the plant still can move in the wind.
A newly planted tree should seldom be fertilized the first year. Once a tree is established, usually after two years, a fertilizer can be applied.
Newly planted trees benefit from mulching, and mulching acts as a barrier to keep lawn mowers away from the tree trunk a leading cause of damage to landscape trees.
