Plant lavender in spring, after your last frost, once the soil has warmed to about 60°F — for most of the US that means April to early June. This gives it a full season to establish before winter. In mild-winter regions (USDA zones 8 and warmer), early fall (September–October) works just as well or better, letting roots settle in during the cool season without summer heat stress. Avoid planting in midsummer heat or while frost still threatens, and always plant into full sun and sharp-draining soil.

Spring: the default choice
For the majority of US gardeners, spring is the right time to plant lavender. Two conditions matter more than the calendar date:
- The last frost has passed. Freshly planted lavender, with tender new roots, can be set back by a late freeze. Wait until your local average last-frost date is behind you.
- The soil has warmed. Aim for a soil temperature of at least 60°F. Cold, wet spring soil rots young lavender roots; warm, drier soil gets them growing quickly.
Spring planting gives the plant the entire summer and fall to develop the deep, drought-proof root system it needs before its first winter. This is the safest option everywhere, and the only sensible option in cold zones.
Fall: great in mild climates
In warm regions (zones 8 and up), early fall is often the superior planting window. Planted in September or October, lavender roots into cool, moist soil without the stress of summer heat, and comes into spring already established and ready to bloom. The key is to plant early enough that roots establish before any cold arrives — a lavender planted too late, with shallow roots, is easily heaved out of the ground by freeze-thaw or lost to winter wet. In cold zones (7 and below), skip fall planting and wait for spring.
Timing by USDA zone
| USDA zone | Best planting window | Notes |
|---|---|---|
| 3–5 | Late spring (after last frost, May–June) | Choose hardy English lavender; spring only |
| 6–7 | Spring (April–May) | Spring preferred; early fall risky |
| 8 | Spring or early fall | Fall lets roots establish in cool season |
| 9–10 | Fall (Oct–Nov) or early spring | Avoid summer heat; fall is often best |
These windows follow your local frost dates, not fixed dates — a cold spring pushes planting later, a warm one earlier. Match the lavender type to your zone too: English lavender for cold areas, French and Spanish types only where winters are mild.
How to plant lavender
- Pick the sunniest, best-drained spot you have — full sun, at least six hours, and soil that never stays soggy. On heavy soil, plant into a raised bed or mound.
- Check and adjust the soil if needed: lavender likes slightly alkaline, lean, gritty soil. Amend clay with coarse sand or grit, and add a little lime to acidic soils.
- Dig a hole slightly wider than the root ball and no deeper — the crown should sit at or just above soil level, never buried, which invites rot.
- Space plants 2 to 3 feet apart for airflow (closer for dwarf varieties, wider for large lavandins).
- Set the plant, backfill, and firm gently. Water in once to settle the roots.
- Mulch with gravel or grit, not bark or compost, keeping it clear of the stem. Gritty mulch reflects heat and keeps the crown dry.
- Water sparingly after that — about weekly through the first season while roots establish, always letting the soil dry between.
Timing and planting mistakes to avoid
| Mistake | Why it fails |
|---|---|
| Planting before the last frost | Late freeze damages tender roots and new growth |
| Planting in midsummer heat | Heat stress on unestablished roots; heavy watering needed, inviting rot |
| Fall planting in cold zones | Roots too shallow to survive freeze-thaw and winter wet |
| Planting into wet, heavy soil | Root rot, the leading cause of lavender death |
| Burying the crown | Traps moisture against the stem base and rots the plant |
After planting
Getting the timing and site right is most of the battle; the rest is a light touch. Follow how to care for lavender for watering, feeding, and winter protection, and once the plant is established, keep it compact and long-lived with how to prune lavender.
