Avocado trees are popular in warmer areas as fruit bearing trees and as indoor potted houseplants in many other areas. In areas where you can grow avocados outside, transplanting directions are very similar to potted avocado instructions. If you are growing indoor avocados, your tree will need periodic re-potting to keep it from becoming root bound.
Remove your avocado from its pot. If it has become root bound, use a hand shovel to separate the roots from the sides of the pot.
Set the tree on the ground and clean the dirt from the roots as much as possible.
Comb out the roots to get an idea of how long they are.
Wipe the blades of your pruners with rubbing alcohol to sterilize them.
Trim about 1/3 of the roots with your sterilized pruning shears before putting the tree in a larger pot. Trim about 1/2 of the roots off if you are transplanting the tree in a similar sized pot.
Put about 2 inches of well draining potting soil in the bottom of your pot.
Put your avocado in its new pot and fill the pot with soil. Water thoroughly.
