Grow an Indoor Herb Garden

Grow an Indoor Herb Garden

Natalie Crofts
Growing your own herbs is as rewarding as it is delicious, filling your home with mouth-watering aromas and your food with added flavour. Cutting that first sprig of rosemary or picking a few fronds from your home-grown dill will have been worth the time and effort when it adds a healthy and delicious new taste to your cooking.
Most herbs are easy to grow, but there are a few basics to get down pat to see them at their best. At this time of year light levels are lower, so growth will be slow but the flavour no less impressive. Choosing a container is easy as herbs will be happy to grow in anything from a recycled yoghurt pot to a plastic seed tray, all you need to do is punch in a few drainage holes if it doesn’t have them already. A saucer, liner or tray will also be necessary to catch any excess water. Once you have your containers, next choose which seeds to sow. Basil, coriander, mint, chives, parsley, thyme, oregano, rosemary… there are a variety of choices, and most herbs will do just as well indoors as they would in the garden. Now you’re ready to begin planting, simply follow these steps…

Pick a location

If you have a bright windowsill, or really sunny spot elsewhere in the house, then you have the perfect place to set up your indoor herb garden. Herbs love sun, in fact it’s what contributes to their flavour and growth, so a strong light source is key to success. A minimum of six hours of direct sunlight per day is best, in a room heated to around 21°C/70°F, which generally suits most homes. Just keep in mind, once grown, the herb’s leaves should not touch the glass as they can burn. Also try to reduce any draft that may come in from the window, as it can become too cold for your plants. Every herb is different, so check seed packets for further tips and information on growing conditions before you sow.

Sow seeds

Scatter seeds liberally across pots two-thirds full of potting mix, spacing each one around 1cm apart. Cover with a thin sprinkling of the mix or compost and water well. You can choose to cover the seeds with a propagator lid or clear plastic bag to speed the germinating process up, removing once the seedlings reach around 1cm in height. Gently spray the seeds daily with water to keep the soil moist, being careful not to soak the soil. When seedlings reach 5cm tall, transplant them into individual pots.

Water wisely

Indoor herbs should be very carefully watered, allowing soil to dry out in between waterings. Test the first couple of inches of soil with your finger to check for moisture before watering, this will encourage the roots to grow deeply as they seek out water, creating a stronger, healthier plant. A slow water two or three times per week should be sufficient. Morning watering is best to allow your herbs to dry out throughout the day – basil in particular does not respond well to evening watering. If your plants begin to droop this does not always mean a lack of water, it could also be they are too hot or positioned too closely together, so consider moving pots back from the window and space further apart before you water again. You can feed your herbs with a seaweed-based fertiliser once per month to boost growth.


Leaves are ready to be harvested as soon as they’re big enough. Continuous harvesting will help to encourage new growth and keep your plants looking shapely, so don’t be afraid to pick regularly. With some herbs, such as mint, just the leaves are required, whilst for others, like rosemary, an entire stem will need to be snipped off so you can strip off its fragrant leaves. Use your herbs as soon as possible after harvesting to retain as much of the beautiful aromatic oils as possible, avoiding washing the leaves.

Dry your herbs

If you want to keep your freshly picked herbs around for longer, then drying them is an option. Cut large branches or clusters off the plant and tie in small bunches. Hang upside down in a dark, well-ventilated room. In around two to three weeks your herbs will be dry enough to store whole, or pick off the leaves and place in an airtight container for up to one year. Gently grinding the herbs before use will help them to release more flavour.
