This is a tropical tree, so it needs to be indoors where temperatures are 60 to 75 Fahrenheit (15-25 C.), or outside of its 9-11 growing zones. ... The tree needs plenty of bright light but it should be indirect.
Water your ficus tree regularly throughout the growing season. Just make sure to allow the compost to dry out a bit before re-watering. Fertilize every three weeks with a well-diluted house plant feed, but only throughout the summer months. The extra nutrients will help to promote new shoots and leaves.
So water every 2 – 3 weeks during the spring and summer (ginseng ficus bonsai trees need to be watered more frequently when it is warm) and then reduce the amount of watering in the autumn and winter months. Remember that the misting should take place every day! Be careful, however.
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 sun. The Bonsai will not tolerate shade at all.
Pruning is a necessity and part of what makes a bonsai a bonsai and not just a plant. You can forego the pruning for a year or longer to achieve a thicker trunk. When ready to prune leaves, a good rule to follow is to prune back to two leaves after six to eight leaves have grown. If you have left the trunk to thicken, new shoots will grow from old wood. But be sure to tend to any substantial wounds with cut paste so disease does not occur.
