Troubleshooting
Golden Lace Cactus problems — and how to fix them
Golden Lace Cactus (Mammillaria elongata 'Copper King') 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
Soft, discoloured base from overwatering or a soggy winter mix. Withhold water, improve drainage, and re-root firm fingers if rot reaches the crown.
Dull, stretched spines
Faded copper colour and elongated stems indicate too little light. Move to direct sun to restore the warm spine tone and compact form.
Mealybugs
White cottony clusters wedge between the dense fingers. Spot-treat with alcohol on a cotton swab and inspect the roots for root mealybugs.
Corking at the base
Brown, bark-like tissue low on older fingers is natural age-related corking, not rot, if the tissue stays firm and dry. No treatment needed.
