Can you grow a curry leaf plant indoors? Yes. The RHS says a curry leaf plant (Murraya koenigii) is only suitable indoors in frost-prone climates, or overwintered in a cool conservatory. Give it full sun, a well-drained, slightly acidic mix, warmth above 40°F (4°C), and let the surface dry between waterings. Winter leaf drop is normal.
Key takeaway: The curry leaf plant is a small citrus-family tree that does well in a bright pot if you respect its winter rest.

What Is a Curry Leaf Plant?
A small aromatic tree, not a herb from curry powder. UC Master Gardeners of Santa Clara County lists it as Bergera koenigii, formerly Murraya koenigii, native to India. The leaves have a citrus-like flavor. The RHS notes up to 10 pairs of leaflets, white scented flowers and red berries that ripen black.
It belongs to the Rutaceae, the citrus family, which matters for pests and plant movement rules covered below.
How Much Light Does a Curry Leaf Plant Need Indoors?
As much as you can give it. Logee’s recommends full sun. Singapore’s NParks says the plant needs at least 6 hours of direct sun to flourish, and in 4 to 6 hours it grows leggy and less lush. Put it in your sunniest window.

What Potting Mix and Pot Should You Use?
A fast-draining, slightly acidic mix in a pot with holes. The RHS recommends acidic to neutral, moisture-retentive but well-drained compost. Logee’s suggests clay pots so roots stay healthy, and says slightly acidic soil keeps the curry leaf plant healthy.
How Often Should You Water a Curry Leaf Plant?
Only when the surface has dried. UC Master Gardeners rate its water need as medium and advise letting soil dry between waterings. Logee’s says to keep it on the dry side in summer and drier still in winter, because excess water promotes root rot. Check with a finger before every drink.
Yellowing plus soggy mix usually means overwatering; see our guide to Pythium root rot for what rotting roots look like.
Why Does a Curry Leaf Plant Drop Leaves in Winter?
It is resting. Logee’s says indoor plants in temperate areas grow from spring through fall and often rest in short winter days, sometimes dropping leaves. Cool temperatures can cause interveinal yellowing first. Raising warmth slows dormancy. If only a bare stem remains, water less and wait for spring regrowth.
How Do You Feed and Prune It?
Feed lightly in growth and pinch often. Logee’s suggests half-strength liquid fertilizer once a week in the growing season, or organic top dressing every 6 weeks. NParks says a high-nitrogen feed after hard pruning helps regrowth. Pinch young tips and prune yearly as growth starts.
- Pinch the growing tips of young plants to force branching.
- Prune older, open plants early in the season.
- Harvest leaves often; NParks says it keeps plants bushy.
- Feed at half strength weekly from spring to fall.
- Stop feeding when winter rest begins.
How Do You Propagate a Curry Leaf Plant?
Seed is easiest but slow. Logee’s says seedlings take a year or two to establish. UC Master Gardeners advise sowing fresh ripe seed at 68°F (20°C) or warmer, with erratic germination that can take over a month. NParks notes seed rots quickly, so sow it immediately. Semi-ripe or woody cuttings also root.
What Pests Attack a Curry Leaf Plant?
Mealybug, scale and spider mite. The RHS lists red spider mite, scale and mealybug, and calls the plant generally disease free. Logee’s recommends repeated neem oil sprays plus strong water jets to dislodge mealybug masses. NParks says pests usually follow stress such as waterlogging, so fix the cause too.
Our guide to mealybugs and scale covers safe controls for indoor plants.
Can You Ship or Move Curry Leaf Plants?
Not out of a citrus quarantine. UC Master Gardeners say curry leaf hosts the Asian citrus psyllid, which spreads citrus greening. Whole plants and leaves cannot leave the quarantine zone. USDA APHIS urges buying certified plants and never moving regulated items out of quarantine, since citrus greening has no cure.
FAQ About the Curry Leaf Plant
Is curry leaf the same as curry powder?
No. Curry powder is a spice blend; curry leaf is a plant.
Why is my curry leaf plant losing leaves?
Usually winter rest from cool temperatures and short days.
How cold can it get?
Keep it above 40°F (4°C) indoors.
Can I dry curry leaves?
You can, but they lose much flavor; freezing is better.
Does it need fertilizer?
Light feeding in spring and summer helps leafy growth.
