How often should I water lavender?

Far less than most plants — overwatering kills more lavender than anything else. Once established, lavender is drought-tolerant and needs watering only every two to three weeks in dry spells, and often not at all if you get regular rain. Water deeply but infrequently, and always let the soil dry out completely between waterings. Newly planted lavender needs more attention for its first season, roughly weekly, while roots establish, but even then err on the dry side. Yellowing leaves and a soft, drooping plant usually signal too much water, not too little.

Why is my lavender dying?

The two big killers are wet feet and poor drainage. Lavender evolved on dry, rocky Mediterranean hillsides and rots quickly in heavy, damp, or clay soil — the roots suffocate and fungal root rot sets in, showing as yellowing, blackening, or a plant that collapses. Too much shade, too much fertilizer, and cutting into old woody stems are the other common causes. If your soil holds water, plant in a raised bed, a mound, or a pot with gritty mix, because no amount of care overcomes soggy roots.

Does lavender need full sun?

Yes — at least six to eight hours of direct sun a day, and more is better. Lavender is a full-sun plant through and through; in shade it grows leggy, blooms poorly, stays damp longer (inviting rot), and generally declines. Give it the hottest, brightest, most open spot you have. A south-facing position against a wall or in a bed with reflected heat is ideal, and good airflow around the plant helps keep the foliage dry and disease-free.

Can lavender survive winter?

It depends on the type and your zone. English lavender (Lavandula angustifolia) is the hardiest, surviving to about zone 5 with good drainage, while lavandins are hardy to roughly zone 6, and French and Spanish types only to zones 8–9. Winter wet is deadlier than winter cold, so sharp drainage is the first requirement. In cold zones, mulch lightly with gravel (not moisture-holding bark), skip fall pruning, and consider growing tender types in pots you can move to shelter.

How to Care for Lavender: Soil, Water, Sun, and Winter

Q: Should you fertilize lavender?

Lavender actually prefers lean, poor soil and needs little or no fertilizer. Rich soil and heavy feeding produce lush foliage but weak, floppy plants with fewer, less fragrant flowers. At most, a light topdressing of compost or a small amount of balanced fertilizer in early spring is plenty, and many gardeners skip feeding entirely with excellent results. A handful of garden lime every year or two is more useful than fertilizer, since lavender likes slightly alkaline soil.

Lavender care is mostly about restraint. Give it full sun (6–8+ hours), sharp-draining alkaline soil, and very little water, feed almost nothing, and prune it once a year — and it will thrive for a decade. The single biggest mistake is kindness: overwatering and rich, damp soil rot the roots fast, because lavender is a dry Mediterranean plant that hates wet feet far more than drought. If yours is struggling, the fix is almost always more sun and less water, not more of either.

Soil and drainage: the make-or-break

More lavender dies from wet, heavy soil than from any other cause. It evolved on rocky, alkaline Mediterranean slopes and needs its roots to dry out between waterings. Aim for:

Fast, sharp drainage above all. If water pools after rain, lavender will rot. Amend heavy or clay soil generously with coarse sand, grit, or gravel, or better yet plant in a raised bed or mound so water drains away from the crown.
Slightly alkaline pH, roughly 6.7 to 7.3. Work a little garden lime into acidic soils. Lavender tolerates a range but is happiest above neutral.
Lean, not rich. Skip the compost-heavy beds; poor soil produces tougher, more fragrant, longer-lived plants.

Container growing is a reliable answer where garden soil stays wet: use a gritty, free-draining mix and a pot with generous drainage holes.

Sun and placement

Lavender wants the brightest, hottest, most exposed spot you can offer — at least six to eight hours of direct sun, ideally more. In too much shade it grows leggy, flowers sparsely, and stays damp long enough to invite disease. A south-facing site, a slope, or a bed near a heat-reflecting wall is ideal. Good airflow matters too: spacing plants 2 to 3 feet apart keeps foliage dry and discourages the fungal problems that plague crowded, humid plantings.

Watering: less is more

This is where good intentions go wrong. Established lavender is genuinely drought-tolerant and needs very little water.

Stage	Watering
Just planted (first season)	About once a week while roots establish; let soil dry between
Established, dry spell	Deep soak every 2–3 weeks at most
Established, regular rain	Often no supplemental water needed at all
In containers	More often than in ground, but still only when the mix is dry

Always let the soil dry out completely between waterings, and water at the base in the morning so foliage stays dry. Yellowing leaves and a soft, sagging plant almost always mean too much water — cut back immediately.

Feeding (barely)

Lavender prefers poor soil and needs little to no fertilizer. Rich feeding gives you lush, floppy growth and fewer, less fragrant flowers. At most, a light topdressing of compost or a small amount of balanced fertilizer in early spring will do; many gardeners feed nothing at all and get better plants for it. A handful of lime every year or two, to keep the soil slightly alkaline, does more good than any fertilizer.

Pruning to keep it young

Annual pruning is what keeps lavender compact and productive instead of woody and sprawling. The essentials: cut back by about a third after flowering in late summer, tidy again lightly in spring, and never cut into the old bare wood, which does not resprout. Skipping pruning is the reason so many lavenders turn leggy and split open within a few years. The full method — timing, technique, and the never-into-wood rule — is in how to prune lavender.

Common problems

Symptom	Likely cause	Fix
Yellowing leaves, soft floppy plant	Overwatering or poor drainage	Water far less; improve drainage or replant in a mound/pot
Leggy, sparse, few flowers	Too much shade or too much fertilizer	Move to full sun; stop feeding
Blackened stems, plant collapses	Root or crown rot from wet soil	Usually fatal; salvage cuttings and improve the site
Woody base, growth only at tips	Never pruned	Begin annual pruning; propagate replacements
Fungal spots, gray mold	Poor airflow and humidity	Space plants out; water at the base only

Winter care by climate

Cold hardiness varies by type, and winter wet is deadlier than winter cold:

English lavender (L. angustifolia) — hardiest, to about zone 5 with excellent drainage. The best choice for cold-winter gardens.
Lavandin (L. x intermedia) — hardy to roughly zone 6.
French and Spanish (L. dentata, L. stoechas) — only to zones 8–9; grow in pots and overwinter under cover in colder areas.

In cold zones, mulch with gravel or grit rather than moisture-holding bark, do not prune hard in fall, and make sure snowmelt drains away from the crown. Container plants are more exposed to freezing and benefit from a sheltered, unheated spot for the coldest weeks.
