Many people grow fruit indoors due to lack of sufficient garden space, inappropriate climate or poor quality soil. Fruit, just like flowers and vegetables, can be grown indoors with success if provided optimal growth conditions. Grow dwarf varieties of your favorite fruit trees in a container garden and eat the produce fresh or use for jams, jellies or desserts. Dwarf varieties are smaller in size than standard fruit trees, growing up to 8 to 10 feet high and 3 to 5 feet wide, but produce equally good fruit.
Position the 10- to 15-gallon container in a bright indoor spot that receives maximum sunlight. Cover the drainage holes of the container with screen mesh to prevent soil from seeping out. Spread a 1- to 2-inch layer of gravel over the base to improve drainage.
Mix 1 part peat, 1 part perlite, bark or vermiculite and 1 part sand to form a well-draining, enriched potting mix. Pour the mix into the container until half full.
Remove the dwarf fruit tree from the nursery container and examine its roots. If roots are pot-bound, prune some larger ones and separate others to facilitate growth in the new container. Lower the plant in the middle of the new container ensuring it lies at the same depth as its previous one. Add or remove potting mix to adjust. Add remaining mix into the container until it's 2 inches below the rim.
Water the container thoroughly and spread a 1-inch-thick layer of gravel, wood chips or bark to form an attractive mulch. After this, water the container evenly only when the top inch of soil feels dry.
Feed the fruit plant a well-balanced, water-soluble fertilizer once a month. Follow label directions for amounts needed.
Prune thin or "leggy" stems and branches of the growing fruit tree to encourage bushiness. Also snip off wayward, low-lying and crossing branches. Pruning maintains shape, size and appearance, which is essential for indoor trees. Never prune more than one-third of the size.
