Pruning

To maintain the shape and size of Alocasia nobilis, it's essential to prune any yellow or damaged leaves regularly. Use sharp, clean scissors to make a clean cut.

Propagation

Common Pests and Diseases

Like all plants, Alocasia nobilis is susceptible to pests and diseases. Here are some of the most common issues you might encounter:

Spider Mites
