Lavender is one of the most rewarding plants you can grow on a Greek property — it handles the summer heat, repels insects, and fills patios, entrance paths, and poolside borders with colour and fragrance. The video above from Garden Answer shows the technique in action; the steps below give you a precise, season-by-season plan adapted for the Mediterranean climate. Whether you manage a holiday rental, a private garden, or a hotel terrace, five minutes of pruning twice a year is all that stands between a lush lavender hedge and a tangled woody mess.
Why Lavender Goes Woody — and Why That Matters
Lavender is a sub-shrub: its base becomes progressively woodier each season. If you never cut back into the softer green growth, the plant devotes energy to maintaining bare, lignified stems rather than producing new shoots and flower spikes. Within three to four years an unpruned plant splits open at the centre, loses its mounded shape, and eventually dies back from the base.
In Greece the situation is accelerated by long, dry summers. Hard pruning at the right moment removes the heat-stressed tips, forces the plant to flush fresh growth before temperatures drop, and resets its vigour for the following season.
When to Prune Lavender in Greece
The Mediterranean calendar differs slightly from northern-European advice. The primary prune happens in late summer to early autumn — typically August through mid-September — once the main flush of flowers has faded but while daytime temperatures are still warm enough to promote a brief regrowth before winter. A lighter tidy-up in early spring (February to March) removes any winter-damaged tips and shapes the plant before the new season's bud break.
Avoid heavy pruning in late autumn or mid-winter: plants pruned too late cannot harden off new growth before cold nights arrive. Equally, do not cut lavender back in the peak of a Greek summer heatwave — wait for temperatures to ease slightly before making major cuts.
How to Prune Lavender: 5 Steps
- 1
Gather the right tools
Use clean, sharp bypass secateurs — never anvil pruners, which crush stems. Wipe blades with isopropyl alcohol or a dilute bleach solution between plants to avoid spreading any fungal disease. A pair of hedge shears works well for larger lavender hedges, but use secateurs for precision work on individual plants. Good sharp cuts heal faster and reduce disease entry points.
- 2
Cut back spent flower stalks immediately after bloom
As soon as flower spikes fade and turn grey-brown, remove them by cutting the stalk down to just above the topmost set of leaves. This first light trim keeps the plant tidy through summer and can encourage a minor second flush of flowers on some varieties such as Lavandula angustifolia and Lavandula x intermedia (lavandin), both of which are common in Greece.
- 3
Make the main annual cut in late summer
After the summer heat softens slightly — typically late August or September — cut the entire plant back by roughly one third. Aim to leave at least 5–8 cm of green leafy growth above the woody base; never cut into bare wood with no leaf buds, as lavender cannot regenerate from dead wood the way roses can. Shape the plant into a neat dome or hemisphere: this compact form sheds winter rain and resists splitting under wind stress.

Apply a light spring tidy in late February or March
Before new growth begins in earnest, run your secateurs over the plant to remove any shoots killed by winter cold or strong winds. You are not removing significant mass here — just tidying frost-burned tips and encouraging even bud break across the whole plant. If the plant has become noticeably lopsided over winter, use this opportunity to even out the shape.
- 5
Feed and water after each pruning session
After pruning, give the plant a light feed with a low-nitrogen, high-potassium fertiliser (tomato or flower feed works well) to support flower production rather than leafy growth. Water the root zone — not the foliage — a day or two after cutting. In Greece's dry climate, a single deep watering is more effective than frequent shallow irrigation, and established lavender should rarely need watering at all outside of the first season after planting.

FAQ
- Can I cut lavender back hard to rescue an old woody plant?
- If a plant has become very leggy and woody at the base, you can attempt a rejuvenation prune by cutting back to about 10 cm from the ground — but only if you can still see some green buds on the lower stems. Do this in early spring and keep the plant well watered. Be warned: some heavily neglected plants will not recover, and it is often easier to replace them. Prevention through annual pruning is always the better strategy.
- Which lavender varieties grow best in Greece?
- Lavandula stoechas (Spanish or French lavender) and Lavandula angustifolia (English lavender) both thrive across Greece. Lavandin hybrids (L. x intermedia) are particularly popular for hedging and commercial use due to their larger size and heat tolerance. All benefit from the same pruning approach, though stoechas varieties typically finish flowering earlier in spring and should receive their main cut in May or June rather than late summer.
- My lavender has brown patches in the centre — is it dead?
- Brown centres usually indicate one of two issues: insufficient pruning over several seasons (allowing the woody core to take over) or a fungal disease such as Phytophthora or Botrytis, which thrive in waterlogged soil. Check drainage first — lavender must never sit in wet soil. If the brown wood has no green buds, those stems cannot be revived. Remove dead sections cleanly, improve drainage with added grit or gravel, and prune the remaining live growth back to green tissue.
