Troubleshooting
Flat-Leaved Dyckia problems — and how to fix them
Flat-Leaved Dyckia (Dyckia platyphylla) 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
By far the most common problem. Treat as a succulent — allow to dry completely between waterings and use a gritty, free-draining mix.
Scale insects
Can colonise the leaf bases where spines overlap. Treat with a dilute neem oil spray, directing the application into the leaf axils.
Physical injury from spines
The stiff, serrated spines are genuinely sharp. Handle with thick gloves and position away from paths in shared spaces.
Pale or yellow leaves
Usually indicates insufficient light. Move to the brightest available position and ensure some hours of direct sun daily.
Mealybugs
White cottony clusters nestled at the leaf base. Remove with a cotton bud dipped in dilute isopropyl alcohol.
