When planting trees, one thing you need to take into consideration before choosing a location is the mature height and spread of the tree. If you may be tempted by all the different species that are offered, take the time to choose carefully, particularly if you have the average size yard, because crowding spoils the growth and appearance of trees, particularly specimen trees.
Browse around this site is typically most economical to plant young trees. Planting an adult tree is difficult and may be expensive if done professionally. This could justify the expense, however, if a mature tree is badly needed for a terrace or for screening. What you are paying or may be the time it takes an inferior tree to mature.
The best time to transplant a tree is in the early spring or late fall. Helpful site can plant trees completely leaf with the aid of wilt-proof sprays that seal the leaves against moisture loss until the roots are established, but this costs money and entails greater risks than buying your tree and planting it in planting season.

When planting a tree over 6 feet in height, it will suffer less setback if moved with a bur lapped root ball.
Since the root system needs fertile soil when it is planted, special steps ought to be taken. Dig the hole 2 feet deep and at the very least 1 foot wider than the full spread of the roots in each direction. Underneath should be broken up with a pitchfork and thoroughly blended with peat, leaf mold, loam, etc.
Manure can be used sparingly and really should only be spread on the top of the hole or it could burn the roots. The deeper you cultivate the hole, the better for the tree. Once planted, you can cultivate around it however, not under the roots. If you hit a layer of creating debris or clay, which is not at all uncommon near a house, you need to remove this layer and replace it with good soil, or on top of that, garden humus.
If you are planting a bare root seedling, you will need to protect it by "heeling in" a vacant flower bed where it can be kept before planting as long as it is dormant.
This means laying it on its side at an angle to the ground and within the roots with good soil. If you are ready to go on it from the soil, give it a mud bath or "puddle" it. This protects the roots from contact with air before planting and in addition from any air pockets which may exist round the roots after planting. After filling the hole to the depth required by the roots of the plant, flood it with water to settle the soil in the bottom; when this has drained away, place the tree in the positioning in which it is to grow and complete the soil around it.
Work the soil round the roots using a stick or shovel handle, and make certain there are no air pockets. Spread the roots naturally, planting the tree at around the same depth as its former location. When the hole is two-thirds, of just how full, tramp it down and fill with water again. Complete the rest of the soil without tramping it down, so that the water will drain towards the trunk.
A balled-and-bur lapped tree is one which has been dug with a good ball of soil where it has been growing in, its root system is thus amply covered and protected. The ball is held set up by a secure covering of burlap and twine. To plant it, set the tree in a hole slightly lower than it stood in the nursery. Work the soil beneath this depth, as described previously.
If the ground is dry, fill the hole with water and let it soak in before planting. Cut the burlap at the very top when you put the tree set up, and roll it back a few inches. You will plant the burlap and all. The burlap will soon rot away.
After the tree is planted it is possible to cut it back sharply. If necessary brace the tree with wire ropes. For the initial year, the more cultivation around the tree the higher, keeping weeds away, too, with straw or mulch, in the spring and fall will help keep the moisture in the bottom.
