Apple trees produce pretty blossoms and tasty fruit. Most apple trees produce better if grown in cooler climates. Apple trees, since they are native to the United States, grow quite well and require little care. Treating apple trees correctly will produce a good harvest in the fall.
Plant apple trees in full sun and an area that has well-drained soil. Slightly acidic soil and loamy rich soil is best for apples. Plant apple trees in the spring.
Water apple trees regularly. Assuming normal rainfall, water trees under one year old once a week for about 10 minutes. When the tree is over a year old, water it once every 2 weeks for 10 minutes.
Fertilize your apple trees once a year with a one cup mixture of 21-0-0, which is ammonium sulfate. Apply the ammonium sulfate in a circle around the base of the tree and water it. Avoid touching the tree trunk with the ammonium sulfate.
Prune your apple trees every year while they are dormant, between late winter and early spring. Remove all damaged, diseased, dead or crossing branches at the base of the tree. Remove any growth at the base of the tree. If the tree is under a year old, allow it to have only one central leader. The central leader is one central branch growing straight out of the trunk with smaller branches growing out of it at crotches. If the tree has two leaders, which is a split at the trunk in which two branches grow instead of just one, remove the weaker of the two leaders and allow only the strongest leader to stay.
