Curry leaf

Sun

Full sun to light partial shade; protect container plants from intense afternoon sun in very hot, dry conditions.

Water

Water thoroughly, then let the surface of the soil dry slightly before watering again. Water much less in cool winter conditions, without letting the root ball dry out completely.

Soil

Fertile, well-drained soil; use a free-draining potting mix in containers. Avoid waterlogged ground and pots standing in water.

Height

10-20 ft (3-6 m); usually smaller in containers

Spread

6-12 ft (1.8-3.7 m)

Flowers

Small, fragrant white flowers in clusters, usually in late spring and summer

Foliage

Evergreen. Glossy green leaves divided into pointed leaflets, strongly aromatic when crushed; foliage may yellow and drop during cool weather.

Growth

Moderate in sustained warmth; slow in cool conditions

Growth rate

Slow

• Move container plants indoors before frost, ideally before nights regularly fall below 50°F (10°C).
• Provide the brightest available indoor position and keep away from cold draughts.
• Feed container plants with a balanced liquid fertiliser at label strength during active spring and summer growth.
• Repot in spring when roots crowd the container, using a pot with drainage holes.
• Mulch outdoor plants to conserve moisture, keeping mulch clear of the trunk.
• Remove unwanted root suckers and fruit where seedlings could spread.

Pruning. In spring, once active growth starts, shorten long shoots just above a leaf joint to encourage branching and keep the canopy within reach. Remove dead wood, and avoid heavy pruning while the plant is cold or dormant.

Pick healthy, fully expanded green leaflets or snip off a whole leafy stalk once the plant is well established and growing strongly. Harvest lightly from young plants, leave plenty of foliage, and use the leaves fresh or freeze them for cooking.

Early spring

As growth resumes, check roots, repot if necessary and prune long shoots.

Spring

Restart feeding and increase watering as new leaves develop.

Late spring

In cool climates, move pots outdoors only after frost risk has passed; introduce direct sun gradually.

Summer

Harvest leaves regularly but lightly, and check leaf undersides for pests.

Late summer

Remove developing fruit if you do not want seedlings or bird-dispersed spread.

Autumn

Bring pots under cover before cold nights and reduce feeding as growth slows.

Winter

Keep frost-free in bright light and water sparingly, especially if leaves have dropped.

• Grow in a large movable pot near the kitchen for convenient leaf picking.
• Use as a small edible specimen tree in a sheltered, frost-free courtyard.
• Combine with lemongrass, ginger and turmeric in a warm culinary planting, allowing each plant its preferred light.
• Use its fine-textured foliage as a light canopy above lower herbs in a tropical edible garden.

Garden styles it suits: Potager (kitchen garden), Edible landscape, Tropical, Modern courtyard, Sensory garden and Small-space.

Plant it with: Lemongrass, Ginger, Turmeric, Chilli pepper and Basil.

Wildlife: Flowers attract bees and other insects, and birds eat the ripe fruit and can disperse the seeds. In parts of its growing range, the foliage supports swallowtail butterfly caterpillars.

• Scale insects and mealybugs: inspect stems and leaf undersides, isolate affected pots and remove small infestations by hand; use a treatment labelled for edible plants if needed.
• Spider mites in warm, dry indoor conditions: look for fine webbing and stippled leaves, rinse foliage thoroughly and repeat checks.
• Root rot from wet soil: improve drainage, empty saucers and reduce watering during cool weather.
• Yellowing or leaf drop after cold exposure: move to a warmer, bright position and water cautiously until growth resumes; do not try to force recovery with fertiliser.

The leaves are not known to be toxic to people when used in normal culinary amounts. Seeds are commonly reported as poisonous and should not be eaten; the likely severity is not well established. Reliable species-specific toxicity information for cats, dogs and horses is limited, so do not treat it as a confirmed pet-safe plant and keep fruit and seeds out of reach.

Where it spreads. It can spread by root suckers and bird-dispersed seed. It is recognised as an environmental weed in parts of south-eastern Queensland and north-eastern New South Wales, Australia; check local advice before planting outdoors.

• Curry plant (Helichrysum italicum)

  A low shrub with narrow silver-grey leaves and yellow flower heads, rather than a green-leaved tree. It smells of curry but is not the usual source of culinary curry leaves.

• Orange jasmine (Murraya paniculata)

  Usually has fewer, broader, glossier leaflets and orange-red ripe fruit; curry leaf has more numerous, narrower leaflets and black ripe fruit. Do not substitute orange jasmine leaves in cooking.

• Neem (Azadirachta indica)

  Typically becomes a much larger tree, with more strongly toothed leaflets and yellowish ripe fruit. Its leaves lack the characteristic culinary curry-leaf aroma.

The common name refers to its use in cooking, while the botanical name honours botanist Johann Andreas Murray and naturalist Johann Gerhard König.

Propagation. Sow fresh seed promptly after removing the fruit pulp; seed loses viability quickly and needs warmth to germinate. Rooted suckers can also be separated carefully during warm weather.
