The Pachira genus is composed of some 24 species. There is some debate whether all Pachira trees sold as house plants are in fact Pachira aquatica, as they're usually labeled, or if some of them are specimens of pachira glabra. Regardless of species, the care instructions for a Pachira money tree remain the same. These sturdy plants are capable of tolerating a wide variety of conditions; they only sure way to kill one is by over-watering it. This plant can grow into a literal tree if given sufficient space, but if pruned back and kept in a small pot, it will remain a decorative foliage house plant.
Pot your Pachira money tree in well-draining soil. Potting soil mixed with river sand does well, or you can mix perlite in to the soil to help improve drainage. The larger the pot you use, the bigger the tree will grow. As a general sizing rule, allow approximately 1 to 2 inches of space between the tree's root ball and the side of the pot.
Place your Pachira tree in a well-lit area, but keep it out of direct sunlight, which may burn the leaves and cause yellow or brown spots at the tips. A bright window covered by sheer curtains is perfect, but the tree can also adapt to a shaded or low-light environment.
Water your money tree sparingly. Some experts recommend watering once a month, but depending on your local conditions you may need to water more frequently. Water once the soil is dry to the touch or as soon as the plant starts to look tired.
Fertilize your Pachira once a month if you desire, but many Pachira tree owners report that the plants thrive with little or no fertilizing. If you do fertilize, use a standard liquid houseplant fertilizer.
Prune the leaves back regularly at stem branchings if you want to encourage thicker, bushier growth. Pruning will also tend to limit the size of the plant. If you're hoping for your Pachira to grow into an actual tree instead of a potted plant, prune only as necessary to remove diseased leaves and stems.
