Pruning
Very soon new branches will start to grow on the main trunk of the bonsai. Pruning the plant regularly encourages new branches to come out. Regular pruning is important to maintain the shape and size of the plant.

Repotting
The plan should be repotted every year for the initial few years to provide optimum support for the growth of the plant. Well-draining soils are suitable for providing medium. The plant needs to be repotted when the roots start appearing at the drainage holes. Repot the plant during an evening, preferably in early spring.
When the main trunk grows to 1 inch (2.54 cm) in thickness, transfer the plant to original bonsai pot. Use the same ratio for the potting medium as the training pot. After repotting, keep the plant in shade for 15 days. Water the plant after repotting whenever the top soil feels dry. Do not wait for the entire medium to go dry before watering it.
Feeding
Ficus benjamina Bonsai is extremely reliant on fertilizers for its regular supply of nutrients. Fertilizers need to be resupplied constantly to keep the plant healthy. It needs weekly feeding, initially, for strong growth.
