The term "ficus" covers a wide range of trees, including many figs and fig-related trees. Ficus can become root-bound after a couple of years in the same pot. Re-potting or trimming the roots of your ficus will help keep it healthy. In some cases, your ficus may lose a few leaves after transplanting. This isn't anything to worry about. Your tree will come back to health over a month or two.
Remove your ficus from its pot. In some cases, you may need to loosen the root ball by slipping a hand shovel between the roots and the side of the pot.
Place the ficus on the ground and examine the root ball. If you are transplanting your ficus into a larger pot, lift the tree up and shake the soil out of the ball.
Comb the roots out with your fingers until you can see their length.
Trim the roots back to the maximum size of the new pot, if transplanting to a new pot. If you are re-planting in the same pot or in a similar sized pot, trim the roots by at least one-third to one-half. Use a pair of alcohol-sterilized pruning shears.
FIll the pot with a 2 inches of potting soil and put the ficus in the pot.
Fill the pot with potting soil. Use your hands to move the soil around the root structure.
