Allergy information
Opuntia stricta can cause skin irritation if you touch its spines or tiny hair-like spines called glochids. People sensitive to cactus spines should handle it carefully and wear gloves. It does not produce airborne pollen that causes allergies.
Common problems
Overwatering can cause root rot. Handling without gloves may cause skin irritation from spines. In humid or cold climates, it may suffer from fungal diseases or frost damage.
Uses
Used as an ornamental plant for xeriscaping and natural fencing. Its fruit is edible and sometimes used in jams or eaten fresh.
Notes
Wear gloves when pruning or handling to avoid skin irritation. Repot only when necessary, as this cactus prefers to be slightly root-bound. Protect from frost in colder climates.
