Gardening Articles: Edibles :: Fruit & Nut Trees
by National Gardening Association Editors
- Select resistant varieties to minimize apple scab and other disease problems.
- Apple trees are not self-fertile; plant at least one other variety that blooms at the same time. Flowering crab apples that bloom at the same time will also pollinate apples.
- Spring planting is recommended in central and northern areas. Where fall and winter weather is generally mild and moist, fall planting is successful.
- Buy dormant, bare-root, 1-year-old trees, if possible. Dwarfs and semi-dwarfs will bear in 3 to 4 years, yielding 1 to 2 bushels per year. Standard-size trees will start to bear in 4 to 8 years, yielding 4 to 5 bushels of apples.
- Choose a site with full sun, moderate fertility, and good air circulation and water drainage.
- Apples will tolerate a wide range of soil types.
- When planting trees on dwarfing and semi-dwarfing rootstocks, be sure the graft union stays at least 1 inch above ground.
- Space standard trees 30 to 35 feet apart, semi-dwarfs 20 to 25 feet apart, and dwarf trees 15 to 20 feet apart.
- Surround each tree with a mouse guard before filling the hole completely.
- Water, prune, and mulch young trees right after planting.
- Water young trees regularly, especially those on semi-dwarfing or dwarfing rootstocks, to ensure that the root system becomes well established.
- Renew the mulch periodically, but pull it away from the tree in the fall so mice don't nest over the winter and eat the bark.
- Begin training trees to their permanent framework in the first season.
- Prune bearing trees annually.
- See our article Fruit Pests and Diseases for controls of common apple pests such as apple maggot, plum curculio, green fruitworm, codling moth, fire blight, and powdery mildew.
- The harvest season ranges from midsummer to late fall, depending on the variety.
- To avoid pulling out the stem when you harvest, cup the apple in your hand, tilt it upward, and twist to separate it from the spur at the point of attachment.
