Troubleshooting
Schied's Pincushion problems — and how to fix them
Schied's Pincushion (Mammillaria schiedeana) 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 primary threat; keep the soil very free-draining and never water in cold or dull weather.
Mealybugs
The dense white spines make mealybugs hard to spot. Inspect the base of tubercles closely and treat with isopropyl alcohol.
Spines browning or discolouring
Aging or pest damage can discolour spines. Ensure maximum light and check for pest activity; discolouration from pests will be localised.
Failure to flower
A cool, dry winter rest period of at least 10 weeks is needed. Keep near a cool window at around 10°C with minimal watering.
Etiolation
Stretching and thinning of the body indicate insufficient light. Gradually move to a sunnier position.
