Lau's Turbinicarpus problems — and how to fix them
Lau's Turbinicarpus (Turbinicarpus laui) 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
Highly susceptible in wet conditions. Use terra-cotta pots and a very porous mix; never water on a fixed schedule — check soil dryness first.
Etiolation
Elongated, pale growth indicates light deficit. Supplement with a full-spectrum grow light if natural sunlight is limited.
Mealybugs
Check the base and between spines for white wax. Treat with isopropyl alcohol on a cotton swab or a neem oil spray.
Failure to flower
Cool, near-dry winter rest (5-10°C) for 8-10 weeks is essential to trigger spring blooming.
Scale
Hard brown patches on the body; treat by physically removing with a soft brush and applying isopropyl alcohol.
