🌲 Lavender

Lavender grows in very well-drained, aerated soil; sandy, gravelly or loamy substrates are ideal. Avoid waterlogged or very clayey soils. Use raised beds or containers and incorporate coarse gravel or sharp sand to improve drainage. Moderately fertile to lean soils suit it best (excess organic matter or high nitrogen content can reduce flowering). Prefers neutral to slightly alkaline conditions (approx. pH 6.5-8); on acidic soils, add lime if necessary.

Sowing seeds (often slow and variable; many lavenders are grown more reliably from cuttings): - Timing: Sow from late winter to spring under cover (recommended), or sow in the open ground in spring only after the risk of heavy frosts has passed and the soil has warmed up. - Pre-treatment: If germination is poor, cold stratify the seeds by placing them in a sealed bag with barely moist medium in a refrigerator for 2 to 4 weeks, then sow. - Sowing method: Use a free-draining seedbed (e.g. with added gravel/perlite). Lavender seeds need light for best germination, so cover only lightly (a layer of fine vermiculite or sand). - Growing conditions: Store at a temperature of approx. 18-21°C in bright light. Maintain regular humidity by misting or watering thoroughly; do not soak. - Germination: Can be slow and irregular (generally 2-6+ weeks). Ensure good air circulation to reduce damping-off. Transplanting and planting: - When seedlings have 2-4 true leaves and are large enough to handle, transplant into small pots of granular, non-draining mix. - Harden off gradually for 7-10 days before planting outdoors. - Transplant after the last frost in full sun and very well-drained soil (sandy/loamy; improve heavy soils with gravel and raised beds). Avoid rich composts that retain water. - Spacing: Plant at a distance of around 30-45 cm (more for taller varieties) to ensure air circulation. - Aftercare: Water to establish the plant, then water sparingly; allow the soil to dry out between waterings. Mulch with gravel rather than organic mulch to keep the crown dry.

Lavender is adapted to lean, well-drained soils and generally needs little or no fertilizer. In flowerbeds, avoid fertilizers with a high nitrogen content (they promote soft, leafy growth, with fewer flowers and a poorer fragrance). If growth is weak, apply a light layer of compost in early spring, or use a low-nitrogen, slow-release fertilizer once in spring (for example, one with a lower first number). Do not fertilize in late summer or autumn, as tender new shoots are more susceptible to winter damage. In containers, nutrients are leached out more quickly; give a little dilute low-nitrogen fertilizer in spring and once more in early summer if necessary, then stop.

Lavender (Lavandula spp., particularly L. angustifolia) is used medicinally mainly as an aromatic (essential oil) and as a mild sedative. Clinical and traditional use confirms its benefits in reducing anxiety/stress and improving sleep quality (aromatherapy or lavender oil-based oral preparations). It is also used topically for minor skin irritations, small cuts/burns and insect bites due to its antimicrobial and anti-inflammatory activity, and as a mild analgesic/antipruritic. Traditional use of the plant includes carminative/antispasmodic effects for mild digestive discomfort.

Lavender flower infusion (Lavandula spp.) is traditionally used as a calming and sleep-inducing drink, to relieve nervous tension and mild anxiety. It is also used for digestive comfort (carminative/antispasmodic effects), notably to relieve indigestion, gas and mild stomach cramps, and can help relieve stress-related headaches. Clinical data on oral lavender preparations suggest potential anxiolytic and sleep-inducing effects, but data specific to herbal teas and infusions are limited.

Pruning lavender keeps the mound compact and long-lasting. After flowering (in late summer), remove wilted flower stems and lightly shear the foliage to reshape it, reducing the current season's growth by about a third. In spring, clean up any winter damage and repeat a light shaping cut once new growth is visible. Always leave a little green foliage on each stem; avoid cutting back old, bare woody stems, as they often don't grow back. In colder climates, do not prune heavily at the end of the season (this can encourage tender shoots that are damaged by frost).
