Troubleshooting
Texas Nipple Cactus problems — and how to fix them
Texas Nipple Cactus (Mammillaria prolifera) 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
Even this vigorous species succumbs to rot if overwatered or pot-bound in waterlogged soil. Good drainage is essential.
Mealybugs
The dense clustering habit makes mealybug colonies hard to spot. Check regularly and treat with isopropyl alcohol or neem oil.
Overcrowding
Clusters can outgrow their pot and start to push offsets off the edge. Repot into a wider, shallower container every 2-3 years in spring.
Scale insects
Scaly brown bumps on the body indicate scale. Scrape off and apply horticultural oil.
Poor fruit set
Fruits develop after pollination. Hand-pollinating between different heads or plants using a soft brush can improve fruit production.
