Santa Rita Prickly Pear problems — and how to fix them
Santa Rita Prickly Pear (Opuntia santa-rita) 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.
Glochid injury
Tiny barbed glochids detach on contact and embed in skin. Use thick gloves and tongs when handling. Remove embedded glochids with tweezers and a magnifying glass or tape-strip method.
Cochineal scale
White waxy cottony patches on pads are the cochineal scale insect (Dactylopius coccus), which produces red dye when crushed. Treat with a forceful water jet or insecticidal soap spray.
Pad rot in wet conditions
Prolonged wet soil or waterlogged conditions, especially in winter, causes pads to become soft and translucent. Improve drainage and reduce watering frequency to prevent recurrence.
