Troubleshooting
Agave filifera problems — and how to fix them
Agave filifera (Agave filifera) 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 rot from overwatering
The most common cause of death indoors. Soft, browning leaf bases mean the mix stayed wet — switch to a grittier mix and water only when bone dry.
Etiolation (stretching)
In low light the rosette loosens, leaves lengthen and the white markings fade. Move to the brightest window or supplement with a grow light.
Mealybugs and scale
These hide in the rosette crown and leaf axils. Wipe with isopropyl alcohol on a cotton bud and inspect new plants before bringing them in.
Sharp terminal spine
Each leaf ends in a hard needle tip; site the plant away from walkways and consider clipping the spine tips if placed near children or pets.
