Don't water your money tree when the soil is still wet or you could overwater it and cause root rot. To check if the soil is dry enough, gently dig down into the soil with your finger. If the soil is dry 1–2 inches (2.5–5.1 cm) down, water your money tree. Once you see water draining out of the holes and into the tray underneath the pot, stop watering. Make sure you keep watering until you see the excess water come out or your money tree might not get as much water as it needs. That way your money tree won't be sitting in water, which can cause root rot. After you water your money tree, wait a few minutes for all of the excess water to drain out of the drainage holes and into the tray. Then, lift up your potted money tree and grab the tray full of water from underneath it. Empty the tray and return it to its place underneath your tree. Money trees grow less during the winter because there's not as much light. Because they grow less, they don't need as much water. During the winter, when you notice the soil your money tree is in is dry, wait 2-3 extra days before you water it. Start watering regularly again once springs arrives.
