Plains Prickly Pear problems — and how to fix them
Plains Prickly Pear (Opuntia polyacantha) 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.
Pad shrivelling in summer
Unlike winter shrivelling (normal), summer shrivelling indicates underwatering or root damage. Check roots for rot and increase watering frequency slightly during the active growing season.
Glochid-caused skin irritation
The fine hair-like glochids of O. polyacantha are particularly tenacious and difficult to see. Use tape-strip removal or fine-tipped tweezers. Avoid rubbing, which drives them deeper.
Crown rot from winter wet
If kept outdoors in a wet winter climate without overhead protection, water pooling at the crown can cause rot. Ensure sharp drainage or provide a rain shelter in persistent wet winters.
