Wrong location of the lucky chestnut
A wrong location is often responsible if the lucky chestnut gets brown leaves. The lucky chestnut is very bright and warm in a favorable location. It does not get a draft and is not constantly being moved.
Lucky chestnut is not cared for properly
Waterlogging in the root area also leads to yellow or brown leaves of the lucky chestnut. Do not water Pachira aquatica until the root ball is almost dry. In winter, reduce the amount of water again.
Never pull lucky chestnuts with braided trunks. This makes the plant very sensitive, so it gets sick faster or gets brown and yellow leaves.
Tips
If the lucky chestnut loses a lot of leaves, this is also a location or maintenance problem. If only a few leaves fall off, don't worry.
