Green Lavender (Yellow lavender) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Full sun for at least 6 hours per day is essential; a south- or west-facing aspect with shelter from cold winds significantly extends its usable outdoor season in marginal climates. If your only bright window faces south, that's perfect for green lavender — same window any aroid would fry on.

Watering

Watering green lavender: low — allow soil to dry almost completely between waterings; water sparingly in winter. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Naturally adapted to summer drought in the Algarve; do not water on a regular schedule. Excess moisture, especially at the root collar in winter, rapidly causes crown rot.

Soil and pot

Green Lavender grows best in sandy or loamy, sharply drained, neutral to slightly acidic (ph 6.0–7.0). Performs best in lean, gritty soil; improve clay-heavy ground with generous quantities of horticultural grit and coarse sand before planting. Do not mulch with organic material close to the stem base. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Green Lavender sits happiest at around Low — tolerates dry Mediterranean-type air humidity and -5 to 35°C (23 to 95°F). Susceptible to Botrytis and froghoppers in still, humid conditions; ensure good air circulation around plants, particularly through winter. If you keep the room above year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed green lavender sparingly. A single light application of a low-nitrogen, high-potassium granular feed in spring is sufficient; over-feeding reduces aromatic oil production and makes plants susceptible to frost damage. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on green lavender in the Growli community. Each is annotated with the most common cause so you know where to start.

• Rosemary beetle (Chrysolina americana) — Adults and larvae graze foliage from late summer onward, leaving plants weakened before winter. Inspect regularly from August; hand-pick beetles at dusk or treat with a contact insecticide registered for edible herbs if needed.
• Xylella fastidiosa (high-risk host) — Green lavender, in common with other stoechas-group lavenders, is classified as a high-risk host for this serious bacterial wilt pathogen. When sourcing plants, buy only from reputable suppliers with appropriate plant-health documentation, especially if importing from southern Europe.

Propagation

Propagate from semi-ripe tip cuttings, 8–10 cm long, taken in mid to late summer; strike in free-draining gritty compost under a polythene tent or in a propagating case at 15–18°C. Seed can be sown in spring at 18–21°C but germinates erratically. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Green Lavender is toxic to pets. ASPCA lists Lavandula as toxic to cats, dogs, and horses. Toxic principles are linalool and linalyl acetate. Clinical signs include nausea, vomiting (not in horses), and loss of appetite. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
