Troubleshooting
Alonso's Turbinicarpus problems — and how to fix them
Alonso's Turbinicarpus (Turbinicarpus alonsoi) 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
Extremely sensitive to overwatering. Use a terra-cotta pot for extra moisture evaporation and ensure the growing medium dries fully between waterings.
Etiolation
Stretching toward light sources signals insufficient sun. Supplement with a grow light if window light is inadequate.
Spider mites
Tiny webbing and stippled surface in hot, dry conditions. Treat with a dilute insecticidal soap spray, avoiding the root zone.
Slow/no flowering
Flowers reliably with a cool, dry winter rest at around 5-10°C and very bright summer light. Without this seasonal cue blooms are rare.
Mealybugs
White wax deposits at the base or between tubercles. Treat promptly with 70% isopropyl alcohol on a cotton swab.
