Ficus microcarpa
Ficus microcarpa (Ginseng Ficus) Care Guide
Featured photoficus-microcarpa.jpgFicus microcarpa is widely grown as the ginseng ficus — a small bonsai-style houseplant with bulging exposed aerial roots that look like bonsai trunks. In nature it is a large strangler fig from southern Asia and Australia. As a houseplant it tolerates indoor conditions better than most tropical figs and is one of the easiest figs to keep small.

Overview
Ficus microcarpa is a strangler fig in nature — starting life on a host tree before encasing it. The bonsai trade exploits its tendency to thicken aerial roots into bulging trunks; what looks like a single trunk is often grafted leaves on a thickened root mass.
Care Priorities
- Bright filtered light keeps growth dense; deep shade thins the canopy.
- Mist the aerial roots if you want them to thicken; they thrive in higher humidity.
- Prune the canopy regularly to maintain bonsai shape.
- Stable temperatures — sudden cold drops cause leaf drop.
Common Problems
Sudden total leaf drop after a move or temperature swing is a stress reaction; new leaves usually emerge within weeks. Yellow leaves are overwatering. White cottony patches between leaves are mealybugs.

Frequently asked questions
Are the bulging trunks really roots?
Yes — most ginseng ficus bonsai are propagated by rooting thick aerial roots and grafting leafy branches on top. The bulging trunk is a thickened root mass.
Why did it drop all its leaves?
Sudden total leaf drop is the classic Ficus stress reaction. The plant usually re-foliates from the same nodes within 4 to 8 weeks if conditions stabilise.
Indoor or outdoor?
Both, in warm climates. In cooler climates keep indoors year-round; outdoor exposure to anything below 10 °C drops leaves.
