Troubleshooting
Sulphur-Yellow Dyckia problems — and how to fix them
Sulphur-Yellow Dyckia (Dyckia sulphurea) 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.
Crown rot
Water pooling in the tight central rosette in low-light or humid conditions causes rot. Ensure good air circulation and water only at the soil level.
Fading silver coating
The silver scurf scales are dust-like and permanent; they do not grow back if physically wiped off. Avoid rubbing the leaves during cleaning.
No flowers
Blooming requires a full-sun position and a cool, dry winter rest. Plants in shade or kept too warm year-round rarely flower.
Root mealy bugs
A white waxy substance around roots at repotting indicates root mealybugs. Treat with a systemic insecticide drench and repot in fresh, dry grit mix.
Spine injuries
The sharp recurved teeth cause painful punctures. Handle with thick gloves whenever repotting or dividing.
