Making Herbal Teas from Garden Plants

Why Grow Your Own Herbal Teas?

There is something deeply satisfying about stepping into your garden, snipping a few leaves, and brewing a cup of tea that cost nothing but care. For anyone interested in seasonal British food and sustainable living, herbal teas are a perfect starting point. They need no special equipment, no long journeys to the shops, and no plastic teabags. Mint, chamomile, and lemon balm all thrive in the UK climate, whether you have a sprawling plot or a few pots on a windowsill. By growing your own, you cut down on packaging, reduce food miles, and reconnect with the seasons. What could be more soothing than a warm mug of chamomile on a cool autumn evening, knowing it came from your own patch?

Mint: The Easiest Place to Start

Mint is the beginner's best friend. It grows vigorously—so vigorously that it is best kept in a pot to stop it taking over. Spearmint is milder and sweeter, while peppermint has a sharper, cooling flavour. Plant in spring in a sunny or partly shaded spot, and water regularly. Harvest leaves from mid-spring to early autumn, ideally mid-morning after the dew has dried but before the sun gets too strong, as this is when the essential oils are most concentrated.

For a fresh cup, take four to six leaves, rinse, and place in a mug. Pour over boiling water, cover with a saucer to trap the volatile oils, and steep for five to seven minutes. Strain and drink. To dry mint for winter, cut whole stems, tie in small bundles, and hang upside down in a dark, airy room. Alternatively, strip the leaves and dry on a mesh rack. Once the leaves crumble easily, store in an airtight jar away from light. Use one teaspoon of dried mint per cup, steeped for five minutes.

Chamomile: Growing Your Own Calm

Chamomile is famous for its calming properties, and it is surprisingly easy to grow. German chamomile is an annual that self-seeds readily, while Roman chamomile is a low-growing perennial. Sow seeds in spring in a sunny spot with well-drained soil. The plants attract pollinators, adding another layer of sustainability. Harvest the flowers when fully open, on a dry mid-morning. Pick them individually or snip off the flower heads.

To dry chamomile, spread the flowers on a tray or rack in a warm, dark place. They dry quickly—usually within a few days. Store in a glass jar. For tea, use one to two teaspoons of dried flowers per cup, or a tablespoon of fresh flowers. Steep in boiling water for five minutes. Chamomile has a gentle apple-like flavour. A word of caution: if you are allergic to ragweed, daisies, or other plants in the Asteraceae family, chamomile may cause a reaction, so introduce it carefully.

Lemon Balm: The Relaxing Lemon Zest

Lemon balm is a generous herb with a bright, citrusy scent that lifts the spirits. Like mint, it can spread enthusiastically, so give it a dedicated pot or a corner where it can roam. Grow from seed or cuttings in spring. The best flavour comes from leaves harvested before the plant flowers, though you can keep picking until early autumn. Regular harvesting encourages fresh growth.

For fresh lemon balm tea, use five or six leaves per cup. Tear them slightly to release the oils, then pour over boiling water and steep for five to seven minutes. It blends beautifully with chamomile for an evening drink. To dry, treat it like mint: bundle, hang, and dry in a dark, airy place. Once dry, crumble the leaves and store in an airtight container. Use one teaspoon per cup. Lemon balm is a gentle nerve tonic, perfect for winding down after a busy day.

Harvesting and Drying: A Practical Guide

Successful drying is all about timing and airflow. Always harvest mid-morning on a dry day, after the dew has evaporated but before the midday heat. Use sharp scissors and a basket so the leaves are not bruised. For air drying, tie stems into small bundles and hang them upside down in a dark, well-ventilated room. For quicker drying, use a dehydrator on a low setting, or an oven on its lowest temperature with the door slightly ajar. The herbs are ready when the leaves rustle and crumble between your fingers.

• Store in glass jars with tight-fitting lids, away from heat and light.
• Label each jar with the herb name and date—most dried herbs keep their potency for up to a year.
• Keep fresh leaves in a dampened paper towel inside a sealed container in the fridge for up to a week.

Brewing and Blending Your Garden Teas

Fresh leaves give a lighter, more delicate infusion, while dried herbs are often more concentrated. Use one tablespoon of fresh herbs or one teaspoon of dried herbs per cup of boiling water. Always cover the cup while steeping to keep the aromatic oils from escaping. Steep mint and lemon balm for five to seven minutes, and chamomile for about five minutes. Strain before drinking.

Try equal parts chamomile, lemon balm, and mint for a soothing evening tea. A pinch of dried lavender or a slice of fresh ginger can add warmth. For a summer iced tea, brew a strong batch, cool it, and serve over ice with a sprig of fresh mint. The sustainability benefits are clear: no teabags, no plastic wrap, no transport emissions. Any spent herbs go straight onto the compost heap. So next time you fancy a cuppa, step outside first. Your garden has everything you need.
