Mammillaria bombycina problems — and how to fix them
Mammillaria bombycina (Mammillaria bombycina) 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 and crown rot
Overwatering or a slow-draining mix rots the base, often unseen until the plant softens or topples. Use a gritty mix, water only when bone-dry, and keep nearly dry in winter.
Etiolation
Insufficient light makes the body stretch pale and lose its compact woolly form. Move to the brightest spot available or supplement with a grow light.
Mealybugs
Cottony mealybugs hide among the wool and spines and are easily missed. Inspect regularly and dab infestations with a cotton bud soaked in dilute alcohol.
Corking and spotting
Stagnant humid air or sunburn from a sudden move into intense sun marks the body. Provide ventilation and acclimatise gradually to stronger light.
