Bunny Ear Cactus problems — and how to fix them
Bunny Ear Cactus (Opuntia microdasys) 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 injuries
The microscopic barbed glochids detach at the slightest contact and are very difficult to remove from skin. Handle only with thick leather gloves or rubber-tipped tongs; never touch bare-handed.
Root and basal rot
Overwatering, especially in winter, is the main killer. Keep dry from October to March and ensure excellent drainage.
Cochineal scale
White cottony masses on the pads, caused by the cochineal insect (Dactylopius coccus). Remove with a strong jet of water outdoors or treat with neem oil or insecticidal soap.
Limp or drooping pads
Indicates either underwatering in summer or overwatering in winter. Check the soil moisture and the season to determine the correct response.
Pale, large pads
New pads grow oversized and pale in insufficient light. Move to a brighter location with more direct sun immediately.
