The Ficus benjamina tree, or weeping fig, is one of the most popular trees to grow indoors. But it also is extremely sensitive and tends to lose all or most of its leaves if things aren't exactly to its liking. That's why it's essential to provide it with proper care.
Put your new ficus plant in a place where it will receive plenty of light but not bright, hot sunshine. A ficus tree is fussy about its environment and will shed some leaves when first brought into a new place, such as your bedroom or sunroom.
Water the tree every week, but check the soil first. More house plants die from over-watering than from under-watering. The more bright light your tree gets, the more frequently you will need to water it, but do not water it unless the top 2 inches of soil feel dry.
Mist the plant every few days to give it a little extra humidity. The ficus, like most houseplants, doesn't like dry air.
Prune your ficus tree or shape it, if needed, in the early spring, when it is beginning a growth period. The plant will be somewhat dormant during the winter months.
Spray the ficus with an indoor houseplant pesticide if you notice yellowing leaves. These are generally caused by spider mites, mealybugs or scales, all common indoor plant pests.
Check your ficus after a few months to see if the roots are crowding the pot. If the plant is rootbound, water will quickly run through and drain out the bottom. At that point, you will need to repot it with fresh potting soil into a pot about 2 inches larger in diameter.
