Aglaonema Osaka problems — and how to fix them
Aglaonema Osaka (Aglaonema 'Osaka') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaves reverting to green
Insufficient light reduces the white variegation. Move closer to a bright indirect light source to maintain contrast.
Scorched white patches
Pale tissue burns easily in direct sun. Diffuse strong light with a sheer curtain or move back from the window.
Brown leaf tips
Dry air or chlorinated tap water. Raise humidity and water with filtered or rainwater.
Yellowing leaves
Usually overwatering or cold. Let soil dry between waterings and keep above 16°C, away from drafts.
