Hi....I also have an Alocasia macrorrhiza and its going crazy.....leaves are around 2 feet long.....how big of a pot do you have yours in? Mine is in a 24 inch pot and its starting to get too small...prob move it up to a 30 or 40....my guess is that the pot you have it in is too small...hope this helps, Brent :)

I bet yours is in the ground in Huntington Beach, right? Is it surrounded my other plants that it competes with for growth and moisture? Have you fertilized it? I believe Dan told me to fertilize mine with a high phosphorus fertilizer like Super Bloom (10-55-10) or something similar. We had tons of rain in the winter in Oklahoma zone 7, and mine is going crazy, like Plantman's. Also, mine is planted in my shady backyard and does well.

Also, ours were very late getting started because we had a very cool spring, virtually no rain until June, and consequently everyone here has had the same issues with late growth.

Mine has never shown any signs of petering out and it must be at least 10 years old. Now granted, I don't grow it outside year round because of where I live. I let it go dormant for the winter and just store it dry. I know the ruber is at least 10 inches long and maybe 5 inches across now. It just keeps getting bigger every year. It also produces at least a couple of offsets each year.

plantman69...one of my a. macrorrhiza is in a 24 in clay pot along with a bunch of moiture-draining impatiens...i guess it's time to pot it up.
susanlynne48...yes, my other a. macorrhiza is planted in the ground, and with a monstera planted about 2 feet away, along with a bunch of assorted bromeliads and other ground cover surrounding it, there's probably too much competition for resources; not much i can do about it...space is such a precious commodity here. i guess i'm just cramming stuff into space i just don't have.
thanks for help and the light of reasoning.
