Troubleshooting
Xanthosoma Albomarginatum problems — and how to fix them
Xanthosoma Albomarginatum (Xanthosoma sagittifolium 'Albomarginatum') 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.
Reversion to green
Low light prompts leaves to lose variegation; provide bright indirect light and remove all-green leaves to preserve the pattern.
Scorched white margins
Direct sun and dry air burn the chlorophyll-poor white edges first; shade from midday sun and raise humidity.
Slow, weak growth
Less chlorophyll means slower growth; do not over-pot or overwater, and feed lightly but regularly.
Corm rot when overwatered
Soggy soil rots the corm, worsened by the plant's slower water uptake; use a free-draining mix and let the surface dry.
