Seed to Harvest Herb Guide
How to grow lavender
A practical guide to starting slow-germinating lavender seed, building a drought-tolerant perennial mound, pruning without damaging old wood, and harvesting fragrant flower spikes.
Before you begin
Lavender succeeds when roots stay airy and crowns stay dry.
Lavender is a sun-loving woody perennial valued for fragrant foliage, pollinator-rich flowers, and stems for fresh or dried use. Seedlings are slow, variable, and sensitive to excess moisture.

Establishment
Begin early and avoid burying the seed
Lavender germination can be slow and uneven, so start more seedlings than the final number of plants needed.
Prepare and sow
Start indoors 10–12 weeks before the last frost. Press seed onto moist mix and cover no more than 1/8 inch.
- A 2–4 week moist chill can improve uniformity.
- Use clean, free-draining seed mix.
- Keep at about 65–70°F after chilling.
Grow seedlings slowly
Expect germination to begin in roughly 14–28 days, with stragglers later. Give emerging seedlings bright light and gentle airflow.
Transplant into drainage
Harden plants for 7–10 days, then set out after frost in full sun and loose, fast-draining soil.
- Space 12–24 inches by mature size.
- Keep the crown slightly above settling soil.
- Avoid low spots and heavy wet clay.
Ongoing care
Grow sturdy plants with lean soil, airflow, and measured pruning
Lavender resents soggy roots and lush, floppy growth caused by excess water or nitrogen.
Give maximum sun
Provide at least 6–8 hours of direct sun for compact growth, fragrance, and abundant flowers.
Water deeply, then dry
Water regularly during establishment; once rooted, irrigate only after the soil has dried well.
Keep crowns dry
Use mineral mulch or bare soil near stems and keep organic mulch away from the woody base.
Prune green growth
Shape after flowering or in spring, always leaving leafy green stems below each cut.
Growth checkpoints
Read the plant from emergence through bloom.
Slow early growth gives way to a branched, aromatic mound once roots establish.
Seedlings emerge
Tiny paired leaves appear unevenly across the tray.
Pot up carefully
Move sturdy seedlings without burying their crowns.
Woody framework forms
Pinching soft tips can encourage branching while plants establish.
Fragrance peaks
Spikes color and the first lower flowers begin to open.

GerminationFew or uneven seedlingsSeed remains dormant or sprouts over many weeks
Sow on the surface, keep temperatures moderate, allow extra time, and try moist chilling before a second sowing.
Crown diseaseRoot or crown rotStems brown from the base while soil stays wet
Improve drainage, reduce irrigation, uncover the crown, and remove plants with soft decayed bases.
GrowthFloppy, sparse floweringLong soft stems produce few fragrant spikes
Increase direct sun, stop high-nitrogen feeding, and prune lightly while retaining green foliage.
Winter injuryBlackened or dead stemsPlants decline after cold, wet weather
Delay major pruning until spring, protect drainage, and choose a cold-hardy English type for exposed sites.
Flower-spike harvest
Cut lavender when color shows and the first florets open
Harvest timing balances fragrance, color retention, stem strength, and value to visiting pollinators.
- Choose: Cut after dew dries, from healthy plants with colored buds and only a few open florets.
- Cut: Take long stems just above leafy green growth; never strip a young plant bare.
- Dry: Hang small loose bundles upside down in a dark, warm, ventilated place.

Questions herb gardeners ask
Lavender growing FAQ
Quick answers for germination, transplanting, drainage, pruning, overwintering, and harvest.
Is lavender difficult to grow from seed?
It is slower and less uniform than many herbs, but fresh seed, patience, bright light, and careful moisture make it manageable.
Should lavender seed be cold stratified?
A 2–4 week moist chill is not always required, but it can improve germination speed and uniformity.
How deep should lavender seed be planted?
Press seed onto the mix and cover very lightly, no more than about 1/8 inch.
How long does lavender take to germinate?
Many seeds emerge in 14–28 days, though later seedlings are common.
When should lavender be started indoors?
Start about 10–12 weeks before the last expected frost so seedlings have time to develop.
How far apart should lavender be planted?
Most varieties need 12–24 inches, but use the mature width listed for the selected variety.
What soil is best for lavender?
Use lean, loose, fast-draining soil. Raised beds or containers help where native soil stays wet.
How often should lavender be watered?
Keep new transplants evenly but lightly moist, then water established plants deeply only after the soil dries.
Does lavender need fertilizer?
Usually very little. Rich nitrogen feeding produces soft growth and fewer flowers.
When should lavender be pruned?
Shape after flowering or once spring growth begins, keeping every cut above living green foliage.
When should lavender be harvested?
For drying, cut when buds are colored and the first lower florets have opened.
Can lavender survive winter?
English types are generally hardiest, but survival also depends on drainage, snow cover, exposure, and local temperatures.
