Lavender is the silver-leaved, purple-spiked shrub that turns a garden into a scene — rows of it humming with bees, the fragrance lifting in the heat, the color glowing against gravel and stone. It is grown for its scent, its long-lasting flowers, its drought tolerance, and the way it draws pollinators. Lavender is genuinely easy — but only if you give it the one thing it cannot do without: sharp drainage and full sun. Most "dead lavender" stories are really stories of cold, wet, heavy soil. Plant it in the right spot and it asks for almost nothing.
Lavender comes from the dry, sunny, rocky hillsides of the Mediterranean and into parts of Africa and Asia. Its home ground is poor, stony, free-draining soil baked by sun, with little summer rain. Everything about lavender care follows from this: it wants heat, sun, lean soil, and dry feet. It evolved its narrow, silvery, aromatic leaves to survive drought and reflect harsh light — the oils that make it smell wonderful also help it resist heat and grazing.
Lavender is a compact, woody, evergreen sub-shrub, usually 30–80 cm tall and wide, forming a neat mound of slender grey-green to silver foliage. From early to midsummer it throws up bare stems topped with dense spikes of small flowers — most famously purple, but also blue, pink, and white. The main garden types:
Full sun — non-negotiable. Lavender needs the hottest, brightest, most open spot you have, with good air movement. Shade gives weak, floppy, short-lived plants. A sunny, sheltered, well-drained position is perfect.
Poor to average, free-draining, even gritty or stony soil — slightly alkaline is ideal. This is the single most important factor. Heavy, rich, or wet soil kills lavender, especially in winter. On clay, plant on a raised mound or in pots, and dig in plenty of grit.
Water new plants through their first summer to establish. After that, lavender is highly drought-tolerant and needs little or no watering in the ground. Overwatering is far more dangerous than underwatering. In pots, water only when the soil is dry.
Do not feed. Lavender wants lean soil; rich feeding gives soft, floppy growth and fewer flowers. Skip the fertilizer and compost.
Pruning is what keeps lavender alive and shapely for years. After flowering (late summer), trim the plant over, cutting back the spent flower stems and a little of the green growth — shape it into a tidy mound. Never cut hard into old, bare, woody stems — lavender does not reliably regrow from old wood. Light, regular trimming each year prevents it from going leggy and woody.
English lavender and lavandin are reasonably hardy (roughly USDA zone 5–8); French/Spanish lavender is more tender. The real winter killer is not cold but cold plus wet soil. Ensure perfect drainage; in heavy, wet, or very cold gardens, grow lavender in pots that can be moved or sheltered.
Plant in spring, into warm, well-drained soil, spacing for air flow. Propagate easily from softwood or semi-ripe cuttings in summer — lavender roots readily. Seed is slow and variable; cuttings keep the variety true.
Lavender is considered low-toxicity and generally safe around the garden. Culinary English lavender is edible in small amounts. Lavender essential oil is concentrated and should not be ingested; in pets, large quantities of plant material or oil can cause mild stomach upset, so it is listed as mildly toxic to cats and dogs — but as a garden shrub it is one of the safer choices, and a strong pollinator and wildlife plant.
Pros
Cons
Not ideal for shady, wet, heavy-clay gardens, or anyone who wants to feed and pamper a plant.
Why did my lavender die? Almost always wet, heavy soil — especially over winter. Lavender dislikes cold combined with damp roots. Improve drainage with grit, plant on a mound, or grow it in pots.
Why is my lavender woody and bare in the middle? It was not trimmed each year. Lavender goes leggy and woody if left unpruned, and it will not reshoot from old bare wood. Trim lightly every year after flowering; once a plant is woody, it is best replaced.
How do I prune lavender? After flowering, trim off the spent flower stems and a little green growth, shaping a neat mound. Never cut back into the old brown woody stems — it may not regrow.
Does lavender need watering? Only in its first summer, to establish. After that it is very drought-tolerant and needs little to no watering in the ground. Overwatering kills it.
Is lavender good for bees? Yes — lavender is one of the best pollinator plants, covered in bees and butterflies all summer.
