Although they can grow up to 60 feet in the wild, money trees kept indoors will typically only grow between 6 and 8 feet tall and can also be trained as a bonsai if you prefer to keep it small. The key to growing a money tree indoors is giving it the right amount of light and water. The good news is that it's difficult to overwater money trees, which makes them ideal for people who have a tendency to kill their plants with too much TLC.
Outdoors, money trees can tolerate direct sunlight, but indoors they should be placed in bright to medium indirect light, for at least six hours a day. They will also do well under fluorescent light.
A well-draining, nutrient-rich potting soil is best for money trees. A peat moss-based mixture would be ideal, but a standard quick-draining soil mixture such as regular cactus or flower soil, will also work. If the soil requires more drainage, you can amend the mixture with sand or gravel.
Money trees should be watered regularly, each time the top inch of soil is dry. Typically they will require more frequent watering in the spring and summer months and should be watered less frequently in the fall and winter. While money trees thrive with lots of water, be careful not to overwater them, as doing so can quickly kill them. The best way to avoid overwatering your plant is to ensure that the potting container and the soil have the proper drainage.
