The ficus tree (Ficus benjamina) thrives when it is slightly root-bound. The tree can go years without needing to be repotted. However, if your ficus tree is growing roots out of the bottom of its container or you can feel roots within the top 2 inches of the soil, the tree must be repotted before the roots are damaged. Another sign that your ficus tree should be repotted is if it is producing smaller-than-normal leaves. Plan to repot your ficus in the spring, if possible.
Place 2 inches of potting soil into the bottom of a pot.
Wrap your hand around the base of the tree. Gently pull and lift it from its pot. If it is hard to lift free, shake the tree gently in a circular motion to help loosen it from its original container.
Set the ficus into its new pot. Add potting soil around the tree to fill in the extra space. Gently tap the pot on a flat surface to help the soil settle. Add more potting soil, if needed.
Water the tree thoroughly. Plan to water the tree every few days to keep the soil moist.
Apply a liquid houseplant fertilizer to the newly potted tree. Follow the dosage directions on the manufacturer's label.
Fertilize monthly through October, then discontinue until the following spring.
