Key takeaways
- Curry leaf is tender, so grow it in a pot and bring it indoors by late September
- Winter leaf drop in the cold is common, and green stems usually reshoot in spring
- Use a 30cm pot of peat-free compost mixed with grit and perlite for sharp drainage
- Feed every two weeks from April to September and pinch out tips for a bushy plant
- Pick whole leaf stems, never more than a third of the plant at once
Curry leaf plant care in the UK comes down to one thing: keeping it warm in winter. Murraya koenigii is a tender tree from India and Sri Lanka, so it lives in a pot, spends summer on a sunny patio and comes indoors before the cold. Get that right and you’ll have fresh, fragrant leaves for your cooking for years.
This guide covers buying the right plant, potting, summer care, winter care, picking and pests.
Why is my curry leaf plant dropping its leaves?
Leaf drop in autumn and winter is usually a reaction to cold. When the plant sits below about 10°C for a while, the leaflets turn yellow and whole leaf stems fall. It’s alarming, but it’s often the plant resting rather than dying.
Check with a quick scratch test: scrape a stem gently with a fingernail. Green and moist underneath means it’s alive. Brown and dry means that stem has died back, so test lower down.
A bare plant needs very little water and no feed. Keep it in the brightest, warmest spot you can, and new shoots usually break from the stems in spring as days lengthen and warm up. Sudden leaf drop at other times of year can also come from a draught, a big move or soggy compost.
Bare stems in winter aren’t the end. If they stay green, fresh shoots usually appear as spring warms up.
Curry leaf or curry plant? How to tell them apart
Garden centres often sell a silver shrub called curry plant. It isn’t the one you cook with.
Curry plant (Helichrysum italicum) has narrow, silvery, needle-like leaves. It’s hardy outdoors and smells of curry when you brush it, but it isn’t the leaf used in Indian cooking. If you like it for its looks, see the guide to growing curry plant.
Curry leaf (Murraya koenigii) is a citrus relative with glossy, dark green leaves. Each leaf stem carries many small paired leaflets. The aroma comes out when you crush a leaflet or drop it into hot oil. It’s tender and hates frost.
Check the label says Murraya koenigii or Bergera koenigii before you buy. If it’s silver and sitting with the hardy shrubs outside, it’s the Helichrysum.
Glossy green leaflets on the left are the real curry leaf. The silver plant on the right is Helichrysum, a different plant altogether.
Where to buy a curry leaf plant in the UK
The true plant takes a little hunting down, as big garden centres rarely stock it.
- Specialist herb nurseries often list Murraya koenigii online, usually as young plants in small pots. Order from late spring to summer so it travels in warm weather.
- Indian grocers sometimes sell young plants in spring. Check the roots have healthy white tips and the leaves look fresh.
Seed is tricky because it must be sown very fresh, so a young plant is the easiest start.
The right pot and compost for curry leaf
In the UK, curry leaf is a pot plant. A pot lets you move it into the sun in summer and indoors for winter.
Mixing grit and perlite into the compost lets water run straight through, which is just what curry leaf roots like.
Use a pot at least 30cm across for a plant two years or older. Terracotta is heavy and breathes, which helps. The roots hate sitting wet, so mix peat-free multipurpose compost with roughly a fifth each of horticultural grit and perlite. Water should run straight through.
Repot every second spring, in April, going up one pot size. Never repot in winter.
Summer care: sun, feeding and pinching out
Move the pot outside once days are reliably warm and nights stay mild, usually June. Pick the sunniest, most sheltered spot you have, such as a patio against a south-facing wall. Get it used to the change over a week or so, starting in light shade.
Water when the top 3cm of compost feels dry, which may be every couple of days in hot weather. Feed every two weeks from April to September with a balanced or high-nitrogen liquid feed, as leaves are the crop.
Left alone it wants to become a small tree. In a pot, pinch out the growing tips every few weeks in summer. Each pinch makes two or three side shoots, so you get a bushier plant and more leaves. Pinch off flower buds too, so the plant puts its energy into leaves. Bring it back indoors by late September, before nights drop towards 10°C.
A sunny, sheltered patio is the perfect summer home. Snap off whole leaf stems from low on the plant.
Where should a curry leaf plant spend winter?
The best winter home is bright and warm, ideally 10-15°C. A heated conservatory is ideal, as it gives good light and steady warmth. A sunny windowsill in a heated room is the next best thing. Keep it away from radiators, which dry the air, and out of cold draughts.
A bright windowsill in a heated room makes a good winter home. Keep it away from radiators and cold draughts.
An unheated greenhouse, porch or garage is too cold. Other tender plants share the same treatment, and the guide to overwintering plants covers the options. The conservatory houseplants guide suggests good companions for a warm conservatory.
In winter, water only when the compost has mostly dried out, a small drink at a time. Don’t feed and don’t repot between October and March.
Month-by-month curry leaf care calendar
This assumes the plant spends winter indoors and summer on a patio.
| Month | What to do |
|---|---|
| January | Keep at 10-15°C in bright light. Water lightly only if the compost is dry |
| February | Scratch-test stems if leafless. Check leaf undersides for spider mite |
| March | Move to the brightest window as light improves. No feed yet |
| April | Shoots start. Begin feeding every two weeks. Repot every second year |
| May | Keep indoors or on the sunniest windowsill. Pinch the first tips |
| June | Move outside to a sunny, sheltered spot once nights are mild |
| July | Main growing month. Pinch tips and pick leaves |
| August | Keep feeding and picking. Pinch off flower buds |
| September | Last feed early in the month. Bring indoors by late September |
| October | Water less. No feed, no repotting |
| November | Some yellowing and leaf drop is normal in a cool room |
| December | Bare stems are fine if green. Don’t overwater |
Spider mite and scale on curry leaf plants
Both pests love warm, dry indoor air in winter.
Spider mite shows as pale speckling on the leaves and fine webbing where leaf stems meet. Stand the pot on a tray of wet pebbles, group plants together, and give the leaves a lukewarm shower now and then. For a bad attack in summer, the predatory mite Phytoseiulus works well, as explained in the guide to spider mite control.
Scale insects look like small brown bumps stuck along stems and leaf midribs, with sticky honeydew below. Scrape them off with a fingernail or damp cotton bud, and repeat weekly for a few weeks to catch the young. The guide to scale insects has more help. Skip home-made soapy sprays, as only approved products can legally be used as pesticides.
Pale speckles and fine webbing are the giveaway signs of spider mite. Dry air from central heating makes it worse.
How to pick curry leaves without weakening the plant
Pick no more than a third of the leaves at once. A pot-grown plant stripped harder than that can stall for weeks while it recovers.
Snap off whole leaf stems where they join the main stem, starting with the oldest, lowest ones. Picking regularly in summer, little and often, keeps the plant bushy.
Fresh leaves keep for about a week in the fridge. For winter cooking, freezing keeps more flavour than drying. Bag whole stems flat, squeeze out the air and use them straight from frozen. The guide to freezing fresh herbs explains the method.
Common mistakes with curry leaf plants
- Binning a leafless plant in winter. Do the scratch test first. Green stems are alive.
- Watering a bare plant every week. With no leaves it uses little water, so soggy compost rots the roots.
- Buying Helichrysum by mistake. Check the label says Murraya koenigii.
- Overwintering somewhere unheated. A cold greenhouse or porch is far too chilly.
- Feeding or repotting in winter. Save both jobs for April.
Frequently asked questions
Why is my curry leaf plant dropping its leaves?
Usually because it’s too cold, below about 10°C. The plant sheds leaves to sit out a chilly winter. Scratch a stem with a fingernail. Green underneath means it’s alive. Keep it bright and on the dry side, and new shoots usually appear in spring.
Can a curry leaf plant survive outside in the UK?
Not through winter, as frost kills it. It’s happy outside on a sunny, sheltered patio from about June to September. Grow it in a pot so you can bring it indoors by late September, before nights turn cold.
Is curry plant the same as curry leaf plant?
No, they’re two unrelated plants. Curry plant (Helichrysum italicum) is a hardy silver shrub that smells of curry. Curry leaf plant (Murraya koenigii) is a tender citrus relative with glossy green leaves, and it’s the one used in Indian cooking.
How do I overwinter a curry leaf plant in the UK?
Keep it indoors at 10-15°C in the brightest spot you have. A heated conservatory or a sunny windowsill both work. Water only when the compost has mostly dried out, and don’t feed or repot between October and March.
How many curry leaves can I pick at once?
No more than a third of the leaves at one time. Snap off whole leaf stems, starting with the oldest, lowest ones. Picking harder than that sets a pot-grown plant back for weeks. Spare leaves freeze well in a bag.
Where can I buy a curry leaf plant in the UK?
Try specialist herb nurseries online or Indian grocers in spring. Garden centres rarely stock the true plant. Check the label says Murraya koenigii (or Bergera koenigii), and order in late spring or summer so it travels in warm weather.
