About This Plant
If you saw a money tree, or Pachira aquatica, in its native habitat of
Central and South American swamps, you probably wouldn’t recognize it.
The tree can grow up to 60 feet tall (versus a max of 3 to 6 feet
indoors), and that ubiquitous braided trunk isn’t a natural feature.
When grown in a nursery, the supple young, green trunks are slowly
braided by cultivators before they harden and turn woody.
Where to Grow
Money trees prefer bright, indirect light and moderate-to-high
humidity. Direct sunlight can lead to leaf-scorching, but the plants can
do relatively well in low light. Exposure to too many drafts, though,
may cause leaf loss. Heater vents and hot, dry air also need to be
avoided.
If you can’t keep your money tree in a bright, steamy bathroom, make it
a humidity-enhancing pebble tray by filling a shallow tray with small
rocks, adding water to partially cover the rocks, and setting the plant
on top.
Money trees can survive outdoors in USDA zones 10 through 12, but otherwise need to be houseplants.
How to Care for a Money Tree
To avoid root rot, a money tree needs a sandy, peat-moss-based soil and
a pot with good drainage. Although it likes humidity in general, you
should let its soil dry out between watering. A good schedule for most
environments is to water when the top 2-4 inches of soil are dry. Water
thoroughly, until water flows out the drainage holes of the pot, and
pour out the excess from the tray so that the roots don’t sit in water.
During the growing season, fertilize once a month with a liquid plant
food at half strength, but skip fertilizer in the winter.
How to Propagate
With clean pruning shears, cut off the tip of a stem with at least two
leaf nodes. Dip the cut end in hormone rooting powder, and place in a
standard potting mix. Keep the soil moist with regular misting until the
cutting roots, in approximately 4 weeks.
Common Problems
Overwatering and too much sunlight are the most common causes of
problems with money plants, though they can also suffer from scale
insects, mealybugs, and aphids. Bugs can be treated with a systemic
insect control, or horticultural oil spray.
Money Tree Bonsai
This tree often comes as a group of five trees braided or twisted
together. To maintain the shape, or to guide the trunks into a braid
yourself, wrap some sturdy string around the tops of the trunks to bind
them together tightly as they grow. Read up on other training techniques
to keep them small and in the shape you want.
