How to Grow Curry Leaf
Bergera koenigii
Curry leaf (Bergera koenigii) is a subtropical aromatic tree prized for its intensely fragrant leaves used fresh in South Indian and Sri Lankan cooking. Grow in a large pot with free-draining compost in a warm, bright spot. Bring indoors before first frost. Feed monthly during growing season. Harvest leaves as needed — picking encourages bushier growth. Fast-growing and rewarding once established. Semi-deciduous in cool climates.
Yearly Lifecycle
Care Essentials
Feed monthly with a balanced liquid fertiliser during the growing season (spring through autumn). Reduce to every 6 weeks in winter. Responds well to iron-rich feeds if leaves yellow.
Watch For
- Scale insects
- Aphids
- Citrus psyllid
- Leaf spot
- Root rot in waterlogged soil
Companions
Lemongrass, Turmeric, Chilli, Coriander
Care Requirements
☀️ Light
Full sun to bright indirect light; minimum 4–6 hours daily
Curry leaf needs strong light to grow well. Outdoors, full sun is best. Indoors, place in the sunniest available spot — a south-facing window is ideal. Insufficient light causes leggy, pale growth.
💧 Watering
Moderate; allow top layer to dry between waterings
Water thoroughly when the top 2–3 cm of compost feels dry. Reduce watering in winter when the plant is semi-dormant. Free-draining compost is essential — root rot from overwatering is the main killer.
🌱 Fertilizing
Monthly balanced feed during growing season; iron supplement if yellowing
Feed with a balanced liquid fertiliser monthly from spring through autumn. If leaves yellow despite good care, apply a chelated iron supplement — curry leaf is prone to iron chlorosis in alkaline conditions.
✂️ Pruning
Annual light prune in late winter; pinch tips through the season
Prune in late winter before new growth begins to maintain a compact, bushy shape. Cut back leggy stems by a third. Pinch growing tips regularly through the season to promote branching and increase leaf production.
❄️ Overwintering
Bring indoors before temperatures drop below 10°C
Not frost hardy — move container plants inside in October or before the first frost. Place in the warmest, brightest spot available. Reduce watering but mist leaves to maintain humidity. Expect some leaf drop — this is normal.
Growing Tips
Harvest regularly to promote growth
Picking sprigs of leaves frequently encourages the plant to branch and produce more foliage. Never strip a branch bare — take a few sprigs at a time from different parts of the plant.
Bring indoors before first frost
Curry leaf is not frost hardy. Move container plants to a bright, warm indoor position when temperatures drop below 10°C. A south-facing windowsill or heated conservatory works well.
Use fresh for maximum flavour
Fresh curry leaves have a pungent, aromatic flavour quite unlike dried ones. Use them within a day or two of picking, or freeze whole sprigs in bags for up to three months.
Watch for leaf drop in winter
Semi-deciduous in cool conditions, curry leaf may drop its leaves in winter — this is normal. Reduce watering, maintain warmth, and new growth will emerge in spring.
Pests & Diseases
Pest Scale Insect
Identification: Brown or tan waxy bumps along stems and on leaf undersides. Sticky honeydew may coat leaves and attract sooty mould.
- Scrape off scales with a soft brush or cotton bud dipped in rubbing alcohol
- Spray with dilute neem oil solution; repeat weekly for 3–4 weeks
- Apply a systemic insecticide drench (acetamiprid); repeat after 4 weeks
Pest Citrus Psyllid
Identification: Small jumping insects on new growth; waxy white tubular secretions on shoot tips; distorted, cupped new leaves.
- Remove and destroy affected shoot tips promptly
- Spray with insecticidal soap or dilute neem oil, covering new growth thoroughly
- Apply a contact insecticide such as deltamethrin to affected shoots
Pest Aphid
Identification: Clusters of small soft-bodied insects on new growth and shoot tips; sticky honeydew and distorted young leaves.
- Blast off with a strong jet of water
- Spray with insecticidal soap solution; repeat every 5–7 days
- Spray with a pyrethrin-based contact insecticide
Disease Leaf Spot Cercospora koenigii / various fungi
Symptoms: Small brown or black spots on leaves, often with a yellow halo. Spots may enlarge and coalesce in humid conditions.
Treatment: Remove affected leaves. Improve air circulation around the plant. Avoid wetting foliage when watering.
Prevention: Water at the base. Ensure good drainage and air flow. Avoid overcrowding.
Disease Root Rot Phytophthora spp.
Symptoms: Wilting and yellowing despite adequate watering; mushy brown roots; plant may collapse suddenly.
Treatment: Remove from pot, trim away all rotten roots, repot in fresh free-draining compost with added perlite or grit.
Prevention: Ensure pot has drainage holes. Water only when top layer of compost is dry. Never let pot stand in water.
