Indoor Herbs You Can Keep Growing Through Autumn

As September rolls in, the garden starts to feel a little different. The evenings draw in, temperatures begin to dip, and some of our summer favourites start quietly calling it a day.

But your herb-growing season doesn’t have to end just because autumn is on the doorstep.

With a sunny windowsill, a few pots and a little regular care, you can keep a surprisingly useful collection of herbs growing indoors well into the cooler months. Better still, having fresh herbs within arm’s reach makes autumn cooking feel instantly more inviting.

Here are some of the easiest herbs to keep growing indoors through autumn, along with a few simple tips to help them thrive.

Basil: Keep the Summer Feeling Going

Basil may have a reputation as a summer herb, but it can continue growing indoors if you give it plenty of light and warmth.

Place your pot near the brightest window you have, ideally somewhere that receives several hours of daylight. Basil dislikes cold draughts, so keep it away from frequently opened doors and chilly window ledges at night.

Harvest leaves regularly by pinching just above a pair of leaves. This encourages the plant to branch out rather than becoming tall and leggy.

Basil is perfect for adding a fresh lift to pasta dishes, homemade pizzas, soups and tomato-based meals when the weather outside is turning decidedly less Mediterranean.

Parsley: Reliable, Useful and Surprisingly Tough

Parsley is one of those herbs that quietly earns its place in the kitchen.

It tolerates cooler conditions better than many herbs and can continue producing leaves throughout autumn when grown indoors. Give it a bright spot, keep the compost lightly moist and harvest the outer stems first, allowing the younger growth in the centre to continue developing.

Flat-leaf parsley has a strong flavour that works beautifully in sauces, soups and roasted vegetable dishes, while curly parsley makes a cheerful garnish and works well chopped into salads and buttery potatoes.

It may not be the flashiest plant on the windowsill, but you will probably reach for it more often than you expect.

Chives: Small Plant, Big Pay-Off

Chives are wonderfully easy-going and take up very little room, making them ideal for smaller kitchens.

They prefer good light but are fairly forgiving, and they can recover quickly after harvesting. Instead of snipping just the very tips, cut a small handful of leaves closer to the base. New shoots will soon take their place.

Their mild onion flavour is brilliant with eggs, soups, baked potatoes, creamy sauces and salads.

If your outdoor chives are still healthy in early autumn, you can also divide a clump and pot a section up to bring indoors.

Mint: Fresh Flavour Without the Garden Takeover

Anyone who has grown mint outdoors will know that it can be rather enthusiastic. Growing it in a pot indoors gives you all that fresh flavour without allowing it to wander freely across the garden.

Mint prefers bright, indirect light and appreciates slightly damper compost than Mediterranean herbs such as rosemary and thyme. Keep harvesting the top growth to encourage a fuller plant.

Use fresh leaves for mint tea, fruit salads, yoghurt dressings, sauces or even tucked into a glass of water with cucumber and lemon. One word of warning: give mint its own pot. It is not particularly interested in sharing.

Rosemary: Made for Autumn Cooking

There is something about rosemary that feels perfectly matched to cooler weather. Its woody, fragrant leaves work beautifully with roast potatoes, root vegetables, breads, casseroles and Sunday lunches.

Rosemary likes plenty of light and does not enjoy sitting in wet compost. Allow the surface of the soil to dry slightly between waterings and make sure your container has good drainage.

Indoor air can sometimes be warmer and drier than rosemary prefers, so avoid placing it directly above a radiator. A bright, cool windowsill is often ideal.

Thyme: Compact and Full of Flavour

Thyme is another excellent choice for autumn because it stays relatively compact and does not need constant attention.

It prefers a sunny position and free-draining compost. Like rosemary, thyme would rather be slightly too dry than permanently soggy.

Its tiny leaves pack a lot of flavour and are particularly good in soups, stews, roasted vegetables, tomato dishes and slow-cooked meals.

Harvest little and often by trimming the softer stems, rather than cutting deeply into old woody growth.

Coriander: Worth Growing in Small Batches

Coriander can be slightly unpredictable in hot summer weather because it has a habit of rushing into flower.

Cooler autumn temperatures can actually make indoor growing a little easier.

Rather than expecting one coriander plant to supply leaves for months, sow small amounts regularly. A fresh pot every few weeks can provide a steady supply of young leaves.

Keep it somewhere bright, water regularly without soaking the compost, and harvest the leaves while they are young.

Fresh coriander is ideal for curries, soups, tacos, rice dishes and homemade chutneys.

Don’t Forget the Light

The biggest challenge for indoor herbs during autumn is not usually temperature. It is light.

As the days become shorter, move your plants towards the brightest windows you have. South-facing windows are particularly useful, although east- and west-facing positions can also work well.

Give pots a quarter turn every few days so plants grow more evenly rather than leaning dramatically towards the glass.

It is also worth remembering that a spot that was bright in July may feel surprisingly gloomy by late October.

Create Your Own Autumn Herb Corner

You do not need a greenhouse, large garden or elaborate indoor growing system to enjoy fresh herbs through autumn.

A handful of pots on a kitchen windowsill can be enough.

Try grouping together three or four herbs you use regularly. Parsley, chives and thyme make an especially practical combination, while rosemary and basil add stronger flavours for cooking.

You could even repurpose attractive mugs, tins or small containers as decorative outer pots, provided the herbs themselves remain in containers with proper drainage.

Suddenly, that ordinary windowsill starts looking rather useful.
