Agave americana 'Marginata' problems — and how to fix them
Agave americana 'Marginata' (Agave americana 'Marginata') 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 heavy soil rots the base, a common killer of agaves. Use sharply draining mix and water only when bone-dry.
Fading variegation
Insufficient light dulls the yellow margins and can cause reversion. Keep it in the brightest direct sun to preserve the contrast.
Sharp teeth and terminal spine
Leaf edges and the pointed tip can inflict puncture wounds; position away from busy paths or carefully trim the tip spine.
Agave snout weevil
Boring larvae cause sudden basal collapse in warm regions. Remove affected plants and keep the rosette unstressed and well-drained.
