Planting a tree correctly involves more than quickly purchasing a tree, digging a hole barely big enough for that tree and walking away. To ensure that a newly planted tree will have a long, healthy life, there are several factors to consider.
One very important thing to think about when planting is the time of year. People often think about planting trees in the spring and summer months when trees are in flower, full of fruit or are covered with beautiful leaves. However, the ideal time to plant is during the tree's dormant season, after leaf drop in the fall and before bud-break in the spring. This time period is the least stressful to the tree because it is not actively trying to grow.
Before purchasing the tree, there is homework to do. One of the most important things to do is to thoroughly research the tree species before the purchase and planting. The end goal is to plant the right tree in the right place. To ensure this, consider the following:
Environmental Factors:
Research how your species will handle the following factors on your potential site: minimum temperature, moisture, soil, light, pollution and compaction.
Trees Purpose:
Why are you planting this tree? Consider your goal and find the species that suit your purpose best. Such purposes include specimen planting, shade, aesthetics, wildlife and windbreaks and screens.
Size:
The potential height and width of your tree is one of the most important factors to consider. All too often, urban trees are cut down because "The tree got too big!" The truth is the tree didn't get too big, it was planted in the wrong place. Large trees can lift sidewalks, grow into pipes or utility lines, block windows, views and solar panels and shade a garden.
Crown Shape:
What form will your tree have? What shape suits you best?
Now that you have thoroughly researched your tree species, it is time to plant the tree correctly. Why is this important? A good planting job will minimize trauma and transplant shock, which could result in slow growth and reduced vigor.
Planting a Containerized or Balled and Burlapped Tree
The following steps should be used when planting a containerized or balled and burlapped tree:
Shallow, broad planting hole: The hole should be dug to the depth of the root ball, and three to five times the diameter of the ball. Place the tree into the hole by holding the ball, not the trunk.
Position the tree: Balance the tree, making sure that it is straight and at the correct height (tree should be planted at the same depth that it was growing in the nursery).
Remove materials: Remove the top portion of wire basket or peel back the top portion of the natural burlap. If there is any plastic string or plastic burlap, remove now or your tree will die.
Fill hole: Fill the hole with about one-third of the soil that you dug to make the hole and gently pack around the root ball. Continue to fill the rest of the hole, while adding water to remove air pockets. Do not add fertilizer for the first year.
Prune: At this time, prune only dead or injured branches. Do not use tree wound paint.
Tree Wrap: Remove any tree wrap that was used for shipping the tree.
Staking: Properly placed and planted trees rarely need to be staked. If staking is necessary, make absolutely certain that the stakes are removed at the end of the first year.
Mulch: Place a 3 inch to 4 inch layer of mulch in a 3 foot to 4 foot diameter circle under the crown of the tree. Pull mulch away from tree trunk so that heat and moisture are not trapped.
Watering: Make sure that the newly planted tree gets a total of one inch of water (either from rain or your garden hose) every week the first year, one inch every two weeks the second year and one inch of water every three weeks the third year.
Planting a Bare Root Seedling
The following steps should be followed if you are planting a bare root seedling:
It is best to plant bare root trees immediately, in order to keep the fragile roots from drying out. If you can't plant because of weather or soil conditions, store the trees in a cool place and keep the roots moist.
Unpack tree and soak in water three to six hours. Do not plant with packing materials attached to roots, and do not allow roots to dry out.
Dig a hole, wider than necessary, so the roots can spread without crowding. Remove any grass within a 3-foot circular area. To aid root growth, turn soil in an area up to 3 feet in diameter.
Plant the tree at the same depth it stood in the nursery, without crowding the roots. Partially fill the hole, firming the soil around the lower roots. Do not add soil amendments (fertilizers).
Shovel in the remaining soil. It should be firmly, but not tightly, packed with your heel. Construct a water-holding basin around the tree. Give the tree plenty of water.
After the water has soaked in, place a 2-inch-deep protective mulch area 3 feet in diameter around the base of the tree (but not touching the trunk).
Water the tree generously every week or 10 days during the first year.

Spring is warm, it's the best time to plant trees. Below is an instruction to follow:
Choose at least a five to six-foot tree grown to nursery standards.
Select a site with enough room for roots and branches to reach full size. Avoid overhead and underground utilities.
Prepare a planting area as deep as the root ball and three to five times its diameter by loosening the soil. Dig a hole in the middle of the area. In heavy clay soil, plant 2-3 inches above the base of the trunk flare (where the roots meet the main stem) rather than at or below the original growing level. If the soil is very sandy, then plant at grade so that the soil at the top of the root ball doesn't erode or dry out. Overall, plant the root ball so that once some settling of the soil occurs, the trunk FLARE is at grade level.
Use water to settle soil and remove air pockets in planting area.
Stake the tree to flex with the wind only if tree is unable to stand up to wind.
Spread a two to three inch layer of mulch on entire area, but not within six inches of tree trunk.
