Why Does My Alocasia Amazonica Polly Go Yellow?

Question

I have had this alocasia for 2 years. It’s been happy, growing new and healthy leaves. However, in the past month or so, I have noticed these spots on the leaves. These extended to the entire leaf in one case (another of the smaller leaves) so I cut the leaf off. Initially the soil was dry so I thought i was under-watering it (I hadn’t watered it for two weeks) so I watered it, but in the past week these spots have extended and appeared on one of the bigger leaves.

Answer 1

This will, primarily, come down to two things:

It needs a little more light, and a lot more food!

Lighting is very important. They need bright, but indirect light. They can endure just a little direct window lighting for a few hours, but if you notice scorching then you will want to cut back. The stretching of the stems tell me that it does need a little more light, though.

They are, also, heavy feeders. They need to be fed quite frequently in container. Feeding them with an all purpose liquid fertilizer once or twice per month will suffice.
