Alocasia drooping

One oldest leaf bending down while the newest is firm may be aging. Several petioles losing firmness together call for a root-ball and temperature check.

While the plant is actively growing

Water a dry root ball evenly and drain it. If the mix is already moist, check for a cold window, trapped runoff, and soft bases. Persistent wet-soil wilt calls for inspecting the roots and corm.

During slower growth

A cooler or darker season can reduce growth and water use. Check moisture before repeating the old schedule. Inspect undersides for mites if leaves are stippled; a new leaf emerging is not, on its own, an explanation for every old leaf that drops.
