Few-Ribbed Matucana problems — and how to fix them
Few-Ribbed Matucana (Matucana paucicostata) 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.
Basal rot
Waterlogged soil causes the base to become soft and discoloured. Remove affected tissue, treat with fungicide dust, and repot in fresh dry mix.
Mealybugs
Check the areoles and spine bases regularly. Treat infestations with isopropyl alcohol or a neem oil spray.
Etiolation
Weak, pale growth leaning toward the light indicates insufficient sun. Increase exposure gradually to prevent sunscorch.
Failure to flower
An annual winter rest at 7-12°C with minimal water is the most reliable trigger for summer blooming in this species.
