Caper plants are drought-tolerant once established, requiring infrequent watering. During hot, dry periods, water deeply every 2-4 weeks, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot, so ensure excellent drainage. Reduce watering significantly in winter during dormancy.

Prune caper plants in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain plant health and shape. Light pruning can also encourage bushier growth and more flower bud production. Avoid heavy pruning during the active growing season.

Caper can be propagated from seeds or cuttings. Seeds require scarification and stratification for successful germination. Semi-hardwood cuttings taken in late summer or early autumn, treated with rooting hormone, and kept in a warm, humid environment, tend to root well. Division is also possible for mature plants.

Repot container-grown caper plants every 2-3 years in early spring, before new growth starts. Choose a pot only slightly larger than the previous one to avoid overwatering issues. Use a well-draining potting mix, ideally formulated for cacti or succulents, and ensure the new pot has ample drainage holes.
