Background

Lavandula stoechas is a Mediterranean lavender distinguished by prominent sterile bracts at the tip of each flower head, giving a butterfly-wing silhouette unlike any other lavender species. It grows more compactly than English lavender and is better suited to warmer, drier climates where reliable drainage is easy to achieve.

Sharply drained soil and full sun are non-negotiable; standing moisture at the root zone is the primary cause of plant loss. Soil pH at or slightly above neutral suits it best. In zone 7 it may die back to the crown in hard winters but often recovers; from zone 8 upward it is typically evergreen. Shearing by one-third after each flush of growth encourages repeat performance and prevents the base from going woody too quickly.

The essential oil of L. stoechas contains camphor and fenchone at higher concentrations than L. angustifolia, distinguishing its fragrance and pharmacology. Research documents antimicrobial activity and anxiolytic effects. Traditional Mediterranean use includes topical application for insect bites, minor wounds, and skin irritation.

cutFirst light shear: On established plants, shear off any winter-damaged tips and shape lightly just as new growth resumes - still cutting into green growth only, never into bare woody stems that won't regenerate.
plantPlant into sharp drainage: Set out nursery plants or rooted cuttings once the soil has warmed and the last frost has passed.
plantTake softwood cuttings: Take 3–4 in non-flowering shoot tips and root them in gritty, well-drained propagation mix.
watchWatch for root and crown rot: Spring rains are when lavender is most at risk.
cutHarvest for drying: Cut stems when about a third of the florets on each spike have opened - this is the point of peak oil concentration.
summer
cutTake 3–4 in softwood cuttings from non-flowering shoots and root them in gritty compost to propagate replacements or expand the planting.
watchMonitor for grey mould on stems and foliage during humid periods; improve air circulation and remove affected material immediately.
cutShear lightly after the second flush to tidy growth; stop well above the woody base to avoid cutting into old wood that will not regenerate.

watchWatch for lavender shab and grey mould: Humid late-summer weather is prime season for lavender shab (stems wilting and dying back from the tip) and botrytis grey mould.
watchStop pruning before frost: Make any last light tidy at least a month before your first frost.
fall
cutIn zones 8–9, give a final light trim to maintain compact shape. In zone 7, leave the season's growth in place to help insulate the crown through winter.
watchStop pruning before frost: Make any last light tidy at least a month before your first frost.
overwinterMulch marginal plants for winter: In zones at the cold edge of a species' range, leave the season's growth in place (don't cut back) and mulch lightly around - not over - the crown after the ground begins to cool.
Common problems

Lavender Shab Disease

Symptoms

Shoots wilt and die back individually while the rest of the plant looks healthy. Small dark fungal bodies may appear on infected stems, and dieback spreads over the season.

Treatment

Prune out and destroy affected stems well below the wilted section, cleaning tools between cuts. Remove severely infected plants. Improve air circulation, avoid overhead watering, and plant in well-draining soil to limit spread.

Phytophthora Root Rot

Symptoms

Wilting despite moist soil, yellowing leaves, stunted growth, and dark, decayed roots and crown tissue. Vines may collapse during hot weather.

Treatment

Plant in well-draining soil and avoid waterlogging. Remove and destroy affected vines. Improve drainage with raised beds or amended soil and avoid overwatering.

Botrytis (grey mould)

Symptoms

Grey fuzzy mould on petals and stems, worst in cool wet conditions.

Treatment

Remove affected parts immediately. Improve air circulation. Avoid overhead watering. Apply copper fungicide if severe.
