The Money Tree, or Pachira aquatica, is a popular houseplant often recognized by its characteristically braided trunk and lush, palmate foliage. Native to the swamps and wetlands of Central and South America, this tropical evergreen is widely cultivated indoors across the globe. Beyond its striking appearance, the plant is associated with good luck and prosperity, making it a favored gift and decorative item. Understanding its natural growth potential is the first step in managing its size within a home environment.
How Big Can a Money Tree Get
The size of a Money Tree depends entirely on its environment, showing a vast difference between its native outdoor habitat and an indoor setting. In its native tropical regions, the Pachira aquatica is a true tree that can reach heights of up to 60 feet. When grown outside in suitable non-native climates, it typically reaches 20 to 30 feet tall.
Indoor growth is significantly restricted by the container size and available light. As a houseplant, the Money Tree typically reaches a manageable height between 6 and 8 feet, often limited by a standard ceiling. It has a slow to moderate growth rate indoors, averaging 10 to 24 inches per year. This slower pace means it takes many years, often 10 to 15, for the plant to reach its mature indoor height.
Although the plant has the genetic potential for massive growth, indoor cultivation naturally stunts its development due to limited root space and environmental controls. In a bright, large indoor space like a sunroom, the plant can sometimes exceed the 8-foot average, potentially reaching up to 15 feet. For most owners, the Money Tree remains a medium to large houseplant whose size is easily contained through regular maintenance.
Environmental Factors Dictating Height
To achieve its maximum potential indoor size, the Money Tree requires consistent access to specific environmental factors that support vigorous growth. The plant thrives best when placed in an area receiving bright, indirect light for at least six hours daily. Insufficient light will cause the growth rate to slow significantly, resulting in smaller leaves and a less robust stature.
As a tropical species, the Money Tree benefits from high humidity levels, ideally above 50%. High humidity promotes the development of large, healthy foliage and supports the metabolic rate necessary for steady vertical growth. In dry indoor environments, using a pebble tray or a small humidifier can help maintain the moist air it needs.
The tree also requires a well-draining, nutrient-rich soil mixture to prevent root saturation, which can lead to root rot and inhibit growth. Consistent, deep watering is necessary, but the soil must be allowed to dry out almost completely between waterings. Providing these optimal conditions encourages the plant to reach its height potential more quickly.
Controlling Size Through Pruning and Potting
The most effective ways to manage and restrict a Money Tree’s size involve mechanical intervention through pruning and strategic potting. Pruning is done primarily to maintain a desired shape and height, and it should be performed during the active growing season, typically in late winter or early spring. When cutting back excessive growth, make a clean cut just above a leaf node.
A leaf node is the small bump on the stem where new leaves or branches originate. Cutting just above this point encourages new, bushier growth to sprout. It is recommended to remove no more than one-third of the plant’s total growth at any one time to prevent excessive stress. If an extremely overgrown tree requires a more aggressive cut, this should be done gradually over multiple seasons to ensure survival.
Pot size plays an equally important role, as the container directly limits the root system, which restricts the overall size of the plant. To keep the Money Tree small and compact, keep it in a smaller pot, since repotting into a larger container encourages growth. When repotting is necessary (typically every two to three years), the new pot should only be one or two inches wider in diameter than the previous one.
To maintain the plant’s current size, owners can employ a technique called root pruning during repotting. This involves gently trimming away a portion of the outer root mass before returning the plant to the same pot with fresh soil. Restricting the root space is a direct method for limiting the Money Tree’s height and canopy spread.
