How to Grow Capers
Capparis spinosa
Capers need sharp drainage, full sun, and minimal water — they come from rocky Mediterranean slopes and suffer in rich or moist soil. Plant at the base of a south-facing wall or in a raised gravel bed. Harvest flower buds daily before they open in summer — those closed buds are the capers. Cut back hard in late winter. Frost-tender below zone 8; mulch or bring containers under glass in autumn.
Yearly Lifecycle
Care Essentials
Sparingly — apply a low-nitrogen, high-potash feed once in spring as new growth emerges. Excess nitrogen promotes leafy growth at the expense of flower buds.
Watch For
- Aphids on new shoots
- Spider mite in hot dry conditions
- Root rot from waterlogged soil
- Frost damage to emerging shoots

☀️ Light
Full sun, at least 6-8 hours daily
Capers need intense, direct sun. A south-facing wall base or open south-facing slope is ideal. Shade reduces flowering dramatically and increases disease risk.
💧 Watering
Minimal — drought-tolerant once established
Water sparingly — established plants need watering only during prolonged drought. Overwatering is the most common cause of death. Excellent drainage is more important than irrigation. Young plants need occasional watering in their first summer to establish.
🌱 Fertilizing
Low nitrogen, once in spring
Apply a low-nitrogen, high-potash feed once in spring as new growth begins. Rich feeding produces leafy, unproductive plants. Do not feed after midsummer.
✂️ Pruning
Hard cutback in late winter, before new growth
Cut back hard to 2-3 buds from the base each late winter. Capers flower on current-year wood — vigorous new growth means more flower buds. Remove any frost-damaged stems entirely.
Growing Tips
Drainage is everything
Capers rot in waterlogged soil. Plant in pure grit or sand-amended soil with a gravel mulch. If in doubt, add more drainage.
Harvest before buds open
A caper bud that opens becomes a flower — beautiful but inedible as a caper. Check plants daily during summer and pick firmly closed buds. Small buds have the best flavour.
Hard prune every winter
Cutting back hard each late winter keeps the plant productive and compact. Capers flower on new wood — the harder you prune, the more buds you get.
Be patient in the first year
Capers establish slowly and may produce only a handful of buds in year one. By year three they become generous producers. Do not over-water or over-feed trying to speed things up.
