Standard sized fruit trees take up much more area the then any of the smaller tree varieties, and they are also harder to keep manageable and to harvest all of the fruit. If you do not prune them at least once a year they can grow as large as thirty feet. If you are just looking for a good tree to provide you with plenty of delicious fruit from and to keep your yard shady, a standard sized tree would be the perfect tree for you. Before you firm up the soil, make sure that the tree is completely vertical and will not fall over. After you have checked that the tree is perfectly vertical you can gently firm up the soil. If the tree's trunk is not yet completely sturdy and can be bent, you need to tie the tree to a stake with a bit of rope. These are beneficial because they take up very small amounts of space and more can be fit in a certain square footage. The only negative aspect is that they produce smaller amounts of fruit per tree. Espalier trees grow with a single vertical stem in the center, and several horizontal branches on each side. Also, staking gives your yard an unnatural look and can present a hazard for people walking or running across the yard. The staking process is actually rather simple. Just take 3 stakes and tie each one separately near the base of the trunk. If you use some sort of tether to prevent rope burn on your tree, that would be an even better solution.

If they are sloped, it is known as a fan. Generally these 2 shapes are used in orchards because of how compact they are. By using them, you allow for many more trees to be in the certain amount of space.
