Indoors, money trees typically grow between 1.8 to 2.4 meters tall. In their natural habitat, they can reach heights of up to 18 meters. The size of your indoor money tree will depend on the care it receives and the conditions in which it is grown. This also includes routine pruning to control shape and size of the tree to make it manageable for indoor spaces. If you prefer a smaller, more compact plant, you can trim back the top growth and encourage bushier, lateral growth.
