Troubleshooting
Mother of Hundreds problems — and how to fix them
Mother of Hundreds (Mammillaria compressa) 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
Caused by overwatering or poorly draining soil. Ensure complete soil dryness between waterings in the growing season and near-dry conditions in winter.
Mealybugs between tubercles
White cottony masses hiding deep in the woolly axils are a common problem. Treat with isopropyl alcohol on a fine brush; repeat every 7-10 days until clear.
Sparse flowering
A dry, cool, bright winter rest is needed to trigger spring flowers. Overwatering in winter or keeping the plant too warm suppresses blooming.
Slow offset production in low light
Insufficient light reduces both spine quality and offset (pup) production. Move to a brighter location to encourage robust growth.
