Light
Your bonsai will need a good amount of light. Indoors, placing it on a windowsill is a good idea. If this is not available, plant lights can aid in growing your ginseng ficus. If you take your tree outdoors during the summer, plan to place it in a spot that gets plenty of sunlight. The bonsai will not tolerate shade at all.
Soil
Ginseng ficus trees do well in a soil mix that is sixty percent aggregate and forty percent organic matter. You can buy a premix or make your own using pine bark, lava rock and a product called akadama which holds water and slowly breaks down over time.
Water
Water your ginseng ficus thoroughly whenever the soil gets slightly dry. Misting the plant daily is a good idea, but do not water to the point where the bonsai is dripping, or else fungal issues can occur. If your plant is in an especially warm environment more frequent watering will be needed.
