Troubleshooting
Eastern Prickly Pear problems — and how to fix them
Eastern Prickly Pear (Opuntia humifusa) 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.
Winter rot from wet feet
Cold it shrugs off, but cold plus wet soil rots the crown. Plant on a slope, in sand or gravel, or in a raised gritty bed so it never sits in winter moisture.
Glochid injury
Tiny barbed glochids at the areoles detach easily and irritate skin badly. Always handle with thick gloves and tongs, especially when harvesting fruit.
Shrivelled, purple winter pads
Pads flattening, wrinkling, and turning purplish in cold is a normal frost-survival response, not disease; they plump back up and green in spring.
Aggressive spread
Pads root wherever they touch soil, so a clump can colonise an area over time. Remove stray pads and site it where spread is welcome.
