Pachira aquatica money tree, also known as the Malabar chestnut, is a tropical perennial valued for its ornamental foliage, attractive flowers, edible nuts and ease of cultivation. The plant blooms during the spring and summer months, producing numerous white flowers that form the seed pods from which the nuts emerge. Native to Central and South America, pachira aquatica money tree thrives only in USDA hardiness zones 10 and 11. Gardeners in cooler zones typically grow the plant in a container for easier transport indoors when temperatures become too cold.
Plant pachira aquatica during late spring or early summer in a location that receives six to eight hours of full sunlight each day and consists of moist, fertile, well-drained soil. Space additional plants at least 8 to 10 feet apart.
Water once every five to seven days during spring and summer to keep the soil moist but not soggy or wet. Decrease the frequency of watering to once every 10 days during fall and once every two weeks during winter. Soak the soil to a depth of at least 12 inches at each application.
Feed pachira aquatica once every month during spring and summer using a 10-10-10 NPK fertilizer. Water the plant before and after applying to prevent root burn and dissolve the granules into the soil. Follow the manufacturer's instructions for proper dosage.
Prune during late winter once every two to three years to keep the plant attractive and healthy. Remove all damaged, diseased, dead or overgrown branches at their point of origin using hedge clippers.
Grow pachira aquatica in a container in all zones but 10 and 11. Grow in full sunlight, water once every five to seven days and feed once per month during spring, summer and fall. Keep outdoors during warm weather, but transfer inside before temperatures drop below 28 degrees F.
