Troubleshooting
Slender Frailea problems — and how to fix them
Slender Frailea (Frailea gracillima) 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
The most common issue, caused by overwatering or a poorly draining mix. Repot promptly, trim affected roots, and allow to dry before replanting.
Mealybugs
White waxy clusters in areoles or at the base. Treat with isopropyl alcohol or diluted neem oil, repeating weekly for a month.
Sunscorch
Yellow-brown patches on one side after sudden exposure to intense direct sun. Acclimatise gradually by moving toward brighter spots over several weeks.
No flowers
Requires a defined winter rest with cool temperatures and minimal water. Warm, wet winters prevent flowering the following summer.
