Agave multifilifera problems — and how to fix them
Agave multifilifera (Agave multifilifera) 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 a water-retentive mix rots the dense rosette. Keep soil gritty, water only when fully dry, and reduce watering in winter.
Loose, thread-poor growth
Insufficient light produces a lax rosette with sparse, weak filaments. Provide full sun to keep the globe tight and the threads abundant.
Mealybugs in the crown
Pests hide among the packed leaves and threads. Inspect the centre regularly and treat with isopropyl alcohol on a cotton bud.
Terminal spine injury
Each leaf ends in a sharp spine despite the soft margins. Site away from walkways and handle carefully when repotting.
