Dwarf fruit trees can grow between 5 and 8 feet, but they produce full-size fruit. No matter what climate you live in, you can grow dwarf fruit trees in pots on your patio and inside your home. Look for dwarf or miniature fruit trees at your local nursery or from online retailers, although shipping may be an issue during cold weather or to a colder climate.
Select a container with at least a 12-inch diameter for growing your dwarf fruit tree. Clay pots work best for holding moisture that's beneficial to fruit trees. Make sure that the container offers good drainage, fruit trees do not like for their feet to stay wet.
Add a layer of rock to the base of the container before you add quality potting soil. Fill the pot halfway with the soil, and then place the fruit tree on top. If the fruit tree is a bare root tree, spread the roots out on top of the soil. If the tree is already in a growing container, squeeze the soil on the bottom to awaken the roots.
Fill the pot with soil up to 1 inch from the rim. The base of the trunk of the fruit tree should be level with the top of the soil and the root ball should be covered with soil.
Water the fruit tree well immediately after planting and at least three to four times weekly as it grows.
Place the pot where it will receive at least 10 hours of sun each day. Southern sun exposure is best. Supplement the tree's natural light with grow lights, especially in the winter. There are a variety of indoor plant lights to choose from; follow the manufacturer's suggestions regarding proximity to the trees and daily usage for the grow lights that you select.
Mist the fruit tree every other day or so with water. Fruit trees love moisture on their leaves.
Fertilize the tree according to the type of fruit you are growing and the potting soil you selected. Some quality soils include fertilizer, so your tree may not need additional fertilizer for 3 months after you plant it.
Remove any dead material from your dwarf fruit tree as it appears. If shooters spring up in the soil around the tree, remove them. Annual pruning varies depending on the type of fruit tree you are growing, but you can plan to cut back between 10 and 20 percent of the old growth each year.
