Monty Don's pruning advice for a healthier, faster-growing lavender
Gardening expert Monty Don has shared a simple task that can help lavender grow faster and look better: pruning. The television gardener advises that to keep lavender in top condition, gardeners should prune the plant every year.
According to Don, the best time to prune is when the flowers begin to fade, which typically falls between midsummer and late summer, depending on the variety. He cautions against waiting until seed heads form or blooms have withered, as the plant needs time to recover before winter.
Regular pruning is essential, as without it, lavender can become woody and misshapen. Don explains that gardeners should prune back firmly but leave some new shoots, as "lavender will often not regrow from bare wood." The resulting new growth will "grow fast and provide an attractive and healthy cover" throughout the winter, forming the basis for the following year's display.
For those looking to expand their lavender collection, Don suggests using the cuttings from pruning to propagate new plants. To do this, take cuttings from side shoots that are free of flowers, ideally with a heel of bark. Trim the base of the stem, leaving a short section of bare stem, and insert the exposed portion into a pot. Water thoroughly and place in a shaded, humid location—a greenhouse or a polythene bag works well. By the following spring, the cuttings should have established strong roots and new top growth, ready to be transferred to a larger pot.
Lavender thrives in UK gardens, particularly in sunny, well-drained positions, making it a popular choice for raised beds, borders, and containers.
How each outlet told it
A framing line is our reading of that outlet's own text — an interpretation, not a quotation and not a fact we assert. Check it against what the outlet published.
AI-extracted; can misattribute a claim — see Methodology.
Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
