Will sage survive a UK winter?

Common sage (grey-green) is hardy through most UK winters (RHS H5) — surviving down to about -15°C. In a sheltered, well-drained spot it stays evergreen. The coloured variegated forms (purple, tricolor, golden) are less hardy (H4) and may lose leaves or die back to the base in a cold winter, particularly on heavy or wet soils. For cold gardens, grow tender forms in pots that can move under cover.

Why has my sage gone leggy and bare at the base?

That's its natural ageing pattern. Without regular hard spring pruning, sage extends its branches outward each year and the base becomes increasingly woody and leafless. Two fixes. (1) Hard-prune in spring — cut back by a third to half each April–May to keep it bushy. (2) Replace every 4–5 years before it gets terminally woody. Take cuttings in late summer to grow replacements.

When should I prune sage?

Late spring — April or early May, after the last frost. Cut back the whole bush by a third to half, into youngish wood (never into old leafless stems). One annual hard prune is all sage needs. Avoid pruning after August — the soft regrowth won't survive winter.

Can I grow sage in a pot?

Yes — and on heavy or wet soils, it's the better option. Use a 30 cm pot with peat-free compost mixed 50/50 with horticultural grit. Full sun. Don't overwater — sage hates wet roots far more than it hates drought. A potted sage lives 4–5 years like an in-ground one and gives you the option to move it under cover in severe winter weather.

Should I let sage flower?

Up to you. Sage flowers (mauve-purple spikes) in June, are extremely good for bees, and don't harm the plant. The leaves are slightly less strongly flavoured after flowering, so for kitchen use some gardeners cut flower stems off as they form to keep leaf production going. Letting it flower is the better choice for wildlife; cutting flowers keeps the harvest stronger.

How do I take sage cuttings?

Late summer (August–early September). Cut 10 cm semi-ripe shoots — the lower half woody, the top still green. Strip the lower leaves. Push the bare stem into a 50/50 mix of compost and horticultural grit. Water once and cover with a clear plastic bag. Roots form in 4–6 weeks. Pot up individually in spring; plant out the following year.

Salbei

Salvia officinalis

Plant sage in a sunny, well-drained spot — Mediterranean origins mean it wants poor, gritty soil and full sun, and it sulks (or rots over winter) in rich or wet ground. Common sage is hardy in most of the UK (RHS H5) and stays evergreen through normal winters; the ornamental coloured forms (purple sage, tricolor sage, golden sage) are tender (H4) and may lose leaves in cold gardens. Buy a young plant in spring — sage is slow from seed and most named varieties don't come true anyway. Replace the bush every 4–5 years before it gets woody and bare at the base. Hard-prune in spring after the last frost to keep it bushy. Pick fresh leaves year-round; the strongest flavour is in early summer before flowering.
