How to Grow Sage in the UK

Sage loves sun and hates wet feet. Give it a bright spot and soil that drains well, and you’ll have soft, fragrant leaves for the kitchen all year. Common sage (Salvia officinalis) is happy in borders, raised beds and pots across most of the UK.

Plants grow 30-90cm tall, depending on the variety. Plant in spring, about 30cm apart, and the RHS guide to growing sage is handy if you want a second opinion. Sage sits nicely alongside the rest of the herb patch in our guide to growing herbs in the UK.

Which sage variety should you grow?

It depends whether you want a kitchen workhorse, a pretty plant, or both. They all like the same sunny, dry spot, but some are tougher than others.

Sages for cooking

Green and purple sage are happy side by side in the same sunny, dry bed.

Common sage is the one for cooking. It grows 40-60cm tall with soft, grey-green, slightly fuzzy leaves. Bees love its purple-blue flowers from June to August. It’s the toughest sage and the best all-rounder. Broad-leaved sage is a form of common sage with bigger, flatter leaves. More to pick, same easy care.

Sages that look the part

Purple sage (‘Purpurascens’) has lovely deep purple-grey leaves. It reaches about 45cm and makes a smart edging plant. It’s good in the kitchen too, just a little milder. It’s less hardy than green sage, so fleece it in cold spells. Tricolour sage (‘Tricolor’) has leaves splashed with green, cream and pink. It grows to about 40cm but is the most tender of the bunch. Give it a sheltered border, or grow it in a pot you can move under cover. It’s fine for cooking but the flavour is weaker. Pineapple sage (Salvia elegans) has bright red flowers in late autumn and leaves that really do smell of pineapple. It won’t survive a UK winter outside. Grow it in a pot and bring it in before the first frost.

Where to plant sage

Pick a warm, sunny spot with soil that drains freely. A wet winter is far more of a threat than a dry summer.

Sun and shelter

Go for the sunniest place you’ve got, ideally six hours of direct sun a day. South or west-facing borders, raised beds and gravel gardens are perfect. In shade, sage gets floppy and flowers less. A warm wall is a treat for sage, with extra heat and shelter from cold winds. It looks and grows well next to lavender and rosemary, so group them together in one sunny, dry patch.

Soil and drainage

Sage likes soil that’s not too rich and drains well. Heavy clay that stays wet can rot the roots in winter. If your ground stays soggy, use a raised bed or a pot instead. Skip the fertiliser and rich compost when planting. Lean soil gives you a neater plant with a stronger flavour. Rich soil makes soft, floppy stems that suffer in frost.

Don’t bury the base of the plant under mulch. Clear fallen leaves away from the stems in autumn so air can move and rain can drain off.

How to prune sage

Pruning is the one job that really matters. Do it well and sage stays bushy for years. Skip it and you’ll end up with a leggy plant with bare stems.

When to prune

Prune in mid-April, once you can see fresh new growth. That shows you exactly where the live stems are. Don’t prune in autumn or winter, as fresh cuts can be hit by frost.

How to do it

Cut leafy shoots back to just above a pair of new shoots or leaves. Don’t cut into old, bare wood, because it often won’t grow back. Older sage gets woody at the base, with leaves only at the tips. When that happens, usually after six or seven years, root a cutting first, then replace the old plant.

Growing sage in pots

A 30cm terracotta pot gives sage room to grow and lets extra water drain away.

Sage does brilliantly in a pot. You’re in charge of the drainage, which is the secret to getting it through a wet British winter.

Picking a pot

Choose a steady pot with drainage holes and room for the roots to spread. Terracotta dries out faster than plastic, but either is fine if you water to suit. Stand it on pot feet if water tends to sit underneath.

Compost and watering

Use peat-free multipurpose compost with a few handfuls of grit or perlite mixed in. Water when the top has dried out, and let it drain before putting a saucer back. Sage, thyme and rosemary make a handy trio for a sunny patio. For more edibles in pots, see our container vegetable gardening guide.

Taking sage cuttings

Cuttings are the easiest way to get new plants. They root readily and give you a copy of the parent. Sage from seed is slow and less predictable.

Softwood cuttings (May to July)

Snip short tips from healthy shoots without flowers. Strip the lower leaves and push the stems into free-draining cuttings compost. Keep the compost lightly moist, in good light but out of hot midday sun. Once they’ve rooted, pot each one up on its own and grow it on before planting out.

Layering (spring or autumn)

Layering is even easier. Peg a low stem down onto the soil, cover part of it with gritty compost and leave the leafy tip showing. Once it has roots, cut it free from the parent. It’s a neat way to replace an old plant in the same spot. Our seed sowing calendar has timings for other herbs and veg.

Sage problems and how to fix them

Sage is happiest in a dry, sunny border with other herbs that hate wet winters. Sage is a healthy herb. Most problems come down to wet soil, poor drainage or skipped pruning, not pests.

Root rot

This is the big one. Soggy soil in winter rots the roots. The plant wilts even though the soil is wet, the stems blacken at the base, then it collapses. Sadly, a rotted plant can’t be saved, so good drainage is everything.

Powdery mildew

A white powdery coating on the leaves, usually in late summer when the air is still and humid. Give plants space, prune to keep them open and airy, and pick off affected leaves. It rarely kills sage but makes the leaves less nice to eat.

Sage leafhopper

Small green insects that leave pale mottled patches on the leaves. The damage is mostly cosmetic and you don’t need to spray. Ladybirds and lacewings help keep them down, and bee-friendly plants nearby bring in more helpful insects. Pick off badly marked leaves if they bother you.

Old, woody plants

This is just sage getting older, not a disease. When leaves only grow at the ends of thick woody stems, take cuttings, then pull out the old plant.

Cooking with sage

Pick leafy tips before the plant flowers for tender leaves and bushier regrowth. Sage is a British kitchen classic. It goes with pork, chicken and rich meats, and sage and onion stuffing is a Sunday roast must. Fresh and dried sage differ in strength, so add a little at a time and taste as you go. Pick clean leaves on a dry day and rinse them if needed. For sage butter, melt butter until it foams, add whole leaves and cook until they crisp and the butter turns golden. Lovely with pasta, gnocchi or roast squash. To dry spare shoots, hang them somewhere warm and airy, then keep the dry leaves in a sealed jar out of the light. Our companion planting guide shows which herbs and veg grow well together. Sage gets on fine near cabbages and other brassicas, since they all like a sunny spot.

Sage care month by month

Here’s what to do and when. March: Check plants for frost damage and snip out dead stems. Don’t prune yet. April: Prune once new growth is clear. Decide whether any old plants need replacing. Get some compost going for new plantings. May-July: Take cuttings. Water pots only in dry spells. Pick leaves often to keep plants bushy. August: Flowers finish. Stop taking cuttings. Water pots less. September-October: Plant out rooted cuttings. Layer low stems to root over winter. Stop feeding. November-February: Common sage needs nothing. Fleece purple and tricolour sage in long freezing spells. Don’t prune or water. Sage earns its spot in any UK garden. If you’re planning your spring gardening jobs, adding a plant in April is a lovely easy win. For more help with edibles, browse the Garden UK growing guides.

Frequently asked questions

Is sage a perennial in the UK?

Yes, common sage comes back every year. It’s a hardy evergreen that keeps its leaves through winter. Give it full sun, good drainage and shelter from too much winter wet.

Why has my sage plant gone woody?

Woody stems are normal as sage gets older. Regular picking slows it down, but most plants get straggly after six or seven years. Root a few cuttings and replace the old plant.

When should I prune sage?

Prune sage in spring, once fresh growth is showing. Shorten the leafy shoots and snip off old flower spikes, but don’t cut into bare old wood.

Can I grow sage in a pot?

Yes, sage is happy in a sunny pot. Use one at least 30cm wide, mix some grit into the compost and keep the drainage holes clear.

How do I take sage cuttings?

Take cuttings in late spring or early summer. Pick shoots without flowers, strip the lower leaves and pop them into free-draining compost.
