Inconsistent soil moisture
Your Money Tree prefers to be watered when 50% of the soil volume has dried out. You can test the soil with your finger or something like a wooden chopstick and if it comes up dry, you can water it. Be careful not to let the soil go bone-dry because ill-timed watering can cause roots to die back and lead to discolored leaves. Be sure that your watering schedule is consistent.
If you accidentally let your Money Tree’s soil dry out completely, it may need a soak in the sink or tub to properly rehydrate the soil. Keep in mind that when the soil goes from bone-dry to saturated, it can cause stress for your Money Tree and cause leaves to drop.
Not enough humidity
Your Money Tree will thrive in slightly humid environments. Increase the humidity around your plant by misting the leaves on a regular basis, using a pebble tray, or moving a humidifier nearby.
Was the plant just moved, shipped, or otherwise shocked?
Generally, houseplants don’t like change. They can be cranky for a few days or even a few weeks after they arrive at your home, or after a move to a new location within your home. Give your plant some time and it will likely recover by itself if all other care requirements are met.
Most of all, be patient!
Let nature take its course – if you’re seeing new growth, keep doing what you’re doing!
