Troubleshooting
Agave toumeyana problems — and how to fix them
Agave toumeyana (Agave toumeyana) 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.
Root and crown rot
Caused by overwatering or dense, moisture-retaining soil. Use a gritty mix, water only when bone dry, and never let the pot sit in a saucer of water.
Etiolation
Insufficient light makes the rosette stretch and loosen and the white filaments diminish. Move to the brightest window or outdoors in summer.
Cold or frost damage
Wet cold causes blackened, mushy leaf tissue. Keep nearly dry below 5°C and protect from hard frost when grown outside its hardiness zone.
Agave snout weevil
Larvae bore into the core, collapsing the rosette. Inspect for soft, leaning growth and remove and destroy affected plants; more a risk on outdoor specimens.
