Troubleshooting
Agave xylonacantha problems — and how to fix them
Agave xylonacantha (Agave xylonacantha) 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
Overwatering or dense soil rots the roots and crown. Use a gritty mix, water only when fully dry, and keep nearly dry in winter.
Loose, green rosette
Too little light loosens the form and greens the leaves. Maximise direct sun to keep the pale colour and tight, armed silhouette.
Injury from spines
The hooked teeth and terminal spine catch skin and pets. Site away from walkways; some growers trim the terminal spine tip on indoor plants.
Mealybugs and scale
Pests shelter at leaf bases and in crevices. Treat with diluted isopropyl alcohol or horticultural soap and inspect regularly.
