About Prickly pear
Opuntia crassa, also known as Prickly Pear or Tuna, is a segmented, shrubby cactus that develops fleshy, flattened, blue-green pads (cladodes) covered with spines or glochids. It is ideal for xeriscapes, rock gardens, or as a focal point in large pots, providing a desert and sculptural aesthetic. Its yellow flowers and edible fruits (tunas) add seasonal interest.
Native range
Central Mexico
Care tips
It requires full sun for optimal growth and abundant flowering. Watering should be sparse, allowing the substrate to dry out completely between waterings, especially in winter to prevent rot. Use a very well-draining substrate specifically for cacti and succulents. A common mistake is overwatering, which can quickly lead to root and pad rot.
How to save a dying Prickly pear
- Warning signs
- Soft, wrinkled, dull pads (underwatering); dark, mushy spots (overwatering/rot).
- First aid
- If soft, water thoroughly, check drainage. If rot, cut affected parts with sterile knife.
- What kills it
- Overwatering, especially in winter or with poor drainage, is its biggest enemy. Withstand the thirst!
- Can it be saved?
- Yes, if rot hasn't advanced far and there's healthy tissue. A cutting from a healthy pad can save it.
