How to start a small kitchen herb garden
A fistful of fresh coriander on top of dal, or a few mint leaves in your chai, costs almost nothing when it grows two steps from your stove. You do not need a garden, only a bright window, a few pots and a little routine. Here is how to get started and avoid the mistakes that kill most first herb pots.
Check your light first
Light decides which herbs will thrive, so look at your space before buying anything. Most culinary herbs want about four to six hours of direct sun a day. Stand at the window at different times and note when the sun actually hits it.
- South or west-facing window with 5+ hours of sun: great for basil, tulsi, curry leaf, rosemary, thyme and oregano.
- East-facing, with a few hours of morning sun: works for coriander, mint, parsley and chives.
- Dim windows: mint and coriander can cope, but growth will be thin. A simple LED grow light on a timer for 10 to 12 hours a day can rescue a shady kitchen.
In hot Indian summers, afternoon sun on a balcony can scorch tender herbs, so shade cloth or a spot with morning sun only works better.
Pick herbs that suit you
Grow what you actually cook. Starting with three or four is more rewarding than ten pots you neglect.
| Herb | Difficulty | Notes |
|---|---|---|
| Mint (pudina) | Easy | Spreads fast, so give it its own pot |
| Tulsi (holy basil) | Easy | Loves sun, pinch flowers to keep leaves coming |
| Coriander (dhania) | Medium | Bolts in heat, so sow often in cooler months |
| Curry leaf | Medium | Slow-growing but long-lived, needs big pot and sun |
| Green chilli | Easy | Not an herb, but thrives in the same conditions |
| Thyme, oregano, rosemary | Medium | Prefer dry soil, so do not overwater |
Choose pots and soil
Any container works if it has drainage holes at the bottom. Without them, roots sit in water and rot, which is the most common reason herbs die. Plastic, clay and recycled tins (with holes punched in) are all fine. Clay dries faster, which suits rosemary and thyme, while plastic holds moisture longer, which suits mint and coriander.
Size matters too. Coriander and mint do well in pots about 20 to 25 cm wide. Curry leaf and rosemary need a bigger pot of 30 cm or more as they grow.
Use a light potting mix rather than heavy garden soil. A simple home mix is roughly equal parts garden soil, cocopeat or sand for drainage, and compost or vermicompost for nutrients. Fill the pot, leaving about two centimetres below the rim so water does not overflow.
Sow or buy a sapling
From seed
Coriander, tulsi and basil grow easily from seed. For coriander, lightly crush whole dhania seeds, soak them overnight, and sprinkle them about a centimetre deep. They sprout in roughly one to two weeks. Keep the soil lightly moist, not wet.
From cuttings or saplings
Mint roots readily: place a stem cutting in water on a windowsill and plant it when white roots appear. Curry leaf and rosemary are slow from seed, so buy a small sapling from a nursery. Look for firm green leaves and no yellowing or pests.
Water, feed and prune
- Water by touch. Push a finger two centimetres into the soil. If it is dry, water until it flows out of the bottom hole. If it is damp, wait.
- Water in the morning so leaves dry before night, which discourages fungus.
- Feed lightly. A spoonful of vermicompost or a diluted liquid fertiliser every three to four weeks is enough. Too much feed gives lots of leaf and little flavour.
- Pinch the tops. Harvesting from the top of the stem makes the plant branch and grow bushier.
- Remove flower buds on basil, tulsi and mint to keep the plant focused on leaves.
Solve common problems
- Yellow leaves and soggy soil: overwatering. Let the pot dry and check drainage.
- Tall, thin, pale stems: not enough light. Move closer to the window.
- Tiny insects or sticky leaves: likely aphids or whitefly. Spray with a mild soapy water solution, or a neem oil spray diluted as directed, and rinse leaves after.
- Coriander flowering early: hot weather. Sow a new pot every two to three weeks in cooler months and keep it in partial shade in summer.
- Droopy plant in the afternoon: check the soil. If it is dry, water, and if it is wet, the roots are struggling.
Harvest and use
Start harvesting once a plant has several sets of leaves. Cut just above a pair of leaves so it regrows. Add coriander, mint and basil at the end of cooking for the brightest flavour, while curry leaves, rosemary and thyme can go in early with hot oil or slow-cooked dishes. Extra mint can be dried or turned into chutney, and leftover stems can be frozen in ice cube trays with a little water.
Final thoughts
Start small with three pots, pick herbs you already cook with, give them sun and good drainage, and water by touch rather than by habit. Expect to lose a plant or two in the first season; that is part of learning. Within a month or two you will be snipping your own leaves, and the flavour in a cup of tea or a bowl of raita makes the effort worthwhile.
