Pachira aquatica, also known by the common names money tree or plant, guiana chestnut, and saba nut, is a tropical perennial tree native to Central and South America. Thriving in wetlands and swamps, Pachira aquatica can reach 60 feet in height under optimal conditions in the wild. With its shiny green foliage and blooms on tall trunks, it has become a popular indoor plant but is also cultivated for its its edible nuts. Pachira is planted as a low-maintenance tropical ornamental in gardens with warm, moist climates, good sun exposure and partial shade in summer.
Determine whether Pachira will grow best as an outdoor plant or an indoor plant in your climate. It's outdoors hardy in USDA Zones 9b to 11 and prefers humidity. Anything cooler and Pachira should be grown indoors.
Provide a humus-rich soil that is well-drained. Add a bit of sharp sand or builders sand to increase drainage in outdoor soils that are heavy in clay. Pachira likes moisture but not for its roots to soak in water constantly, so drainage is key. If planted in a container indoors or out, make sure there are adequate drainage holes to release excess or stale water.
Place Pachira in a sunny to partial-shade exposure outdoors daily. In very warm climates or during the heat of summer, light shade is a better option to prevent leaf burn. For indoor plants, provide bright indirect light and turn the plant regularly toward the light source to keep it growing straight and leafing evenly.
Water Pachira deeply and consistently so that the soil is evenly moist at all times but not soaking wet in standing water.
Fertilize indoor and outdoor Pachira trees lightly three to four times a year with a good-quality water-soluble organic fertilizer applied around the roots at the drip line.
Prune away any dead, damaged or diseased leaves and branches as soon as you see them.
