Why a Small Patio Suits Herbs So Well

Herbs are, almost without exception, plants that give their best in tight quarters. The ones we cook with most — thyme, rosemary, oregano, sage — come from rocky Mediterranean hillsides where the soil is thin, the drainage is sharp and the sun is relentless. A pot on a warm patio mimics that life far better than a rich border ever could. Even on a modest slab of paving outside the kitchen door, you can raise enough parsley, mint and basil to change the way you cook, and the trip from chopping board to pot takes seconds.

Containers solve problems too. Mint, which spreads like gossip, stays put in a pot. Tender herbs such as basil can be shifted under cover when the weather turns. And on a genuinely small patio you can grow upwards — a ladder of pots, a wall trough, a hanging basket of trailing thyme — without surrendering a single inch of sitting space.

Herbs That Cope With British Weather

Our summers are warm enough for herbs but rarely hot, and our winters are wet rather than truly cold. That combination kills more pots through soggy roots than through frost, so choose with both in mind.

• Hardy perennial stalwarts: rosemary, thyme, sage, oregano, winter savoury, chives and bay. These will sit outside all year in most of the UK, provided the compost drains freely.
• Mint: reliably hardy, but always give it its own pot — it will smother anything sharing its space.
• Parsley and chervil: biennial or short-lived, happy in half shade, and best sown fresh each spring rather than coaxed through winter.
• Tender summer herbs: basil, dill, coriander and lemon verbena. Treat basil as a summer visitor — it sulks below about 10°C and blackens at the first hint of frost.
• Coriander: grows fast and bolts fast. Sow a few seeds every three weeks from April to July rather than one big sowing, and you will have leaf all season.

The Right Pot, Compost and Drainage

Size matters more than style. A 30cm pot holds a rosemary or a decent clump of chives comfortably; anything smaller dries out twice a day in July. Terracotta looks lovely and breathes well, but it wicks moisture away fast, so plastic or glazed pots are kinder if you are out at work. Whatever you choose, the pot must have drainage holes, and it must not sit flat in a puddle.

Use a peat-free multi-purpose compost for leafy herbs such as parsley, mint and basil. For the Mediterranean woody types, mix in a good handful of horticultural grit per pot to keep it open, or use a loam-based compost with grit added. Stand pots on feet or broken tiles so water escapes, and keep saucers only for the height of summer — in winter they turn into small ponds. Repot or top-dress every second spring, teasing away the top few centimetres of tired compost and replacing it.

Where to Put Them

Aim for at least six hours of sun for thyme, rosemary, sage, oregano and basil. Mint, parsley and chervil will manage on four. Shelter matters as much as sun: a south-facing wall stores heat through the evening and protects tender leaves from wind, which shreds basil and dries out small pots quickly. In a really exposed spot, group pots together — they shade each other's compost and create their own humid microclimate. Turn them a quarter-turn each week so the whole plant, not just the sunny side, fills out.

Watering and Feeding Without Fuss

From May to September, most pots need a daily check, and on hot days a morning watering plus an evening top-up. Water until it runs out of the base, ideally in the morning so leaves dry before night and disease has less to work with. Rain does not always reach a crowded pot, so do not assume a wet day has done the job.

Feeding is where keen growers go wrong. Woody Mediterranean herbs want a lean life; a fortnightly dose of dilute liquid feed is plenty, and too much produces soft, flavourless growth. Leafy herbs — basil, parsley, mint — appreciate a weak general feed every fortnight. Chives and mint in particular reward a light feed after each cut.

Harvest Little and Often

Regular picking is what keeps these plants productive, not the other way round. Herbs that are never cut grow leggy, flower early and lose flavour.

• Basil: pinch out the growing tip just above a pair of leaves, and it will branch into two stems. Keep doing it and remove any flower buds on sight.
• Mint: cut whole stems back to a leaf joint, taking no more than a third of the plant at once. A hard cut in midsummer gives you a fresh flush of tender leaves.
• Chives: snip to about 2.5cm from the base rather than trimming the tips. They regrow in a fortnight.
• Parsley and coriander: take the outer stems first, cutting low, and leave the crown to keep producing from the centre.
• Thyme, rosemary, sage and oregano: harvest from the top, never more than a third at a time, and avoid cutting into old bare wood, which rarely regrows.

By late September, lift a pot of basil or parsley onto a bright windowsill indoors and keep picking. The hardy herbs can stay out, but raise them onto feet, clear the saucers and ease off the watering — a cosy, well-drained pot will carry thyme and rosemary through to next spring, ready for another season of nipping out to the patio mid-recipe.
