When to plant chervil
Chervil is a fine-leaved herb best planned around cool growing conditions. A small sowing in a suitable season can be more useful than trying to keep an ageing plant productive through hot weather.

Timing, in frost-relative terms
These offsets are the starting assumptions used by our calendar for chervil. They do not establish suitability in every climate. Your seed packet, cultivar and local growing advice take priority; in frost-free places the calendar uses monthly temperature patterns instead.
- Sow direct 4 weeks before the last frost.
- Expect 60–80 days to maturity, counted from sowing.
- Sow again every 21 days for a continuous supply.
- Can also be sown in late summer for an autumn crop or to overwinter.
Getting the timing right
Sow where it will grow, or into its final container, because moving established roots can check growth. Seed needs light for germination; avoid burying it deeply. Keep the surface moist while seedlings emerge.
Frost tolerance
Check the named variety and local forecast before exposing young growth. The catalog cold-damage figure is a reference, not a guarantee: plant age, acclimatisation, wind and the duration of a freeze affect damage.
Classified as hardy, with a catalog cold-damage reference of -8°C (17.6°F)17.6°F (-8°C). Exposure duration, growth stage and acclimatisation change cold tolerance.
Before you plant chervil
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 5°C (41°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
- Frost tolerance does not make saturated or frozen soil suitable for planting. Wait until the bed can be worked without smearing or compacting it.
- Use the maturity range on your seed packet when choosing a variety. Cold, short days and transplant stress can make harvest later than the calendar estimate.
Use the cool season for delicate chervil leaves
Sow where it will grow, or into its final container, because moving established roots can check growth. Seed needs light for germination; avoid burying it deeply. Keep the surface moist while seedlings emerge.
Provide drained soil and a position with suitable light that does not dry rapidly. Pick tender leaves for immediate use and watch for slug damage among young seedlings. Keep the crop labelled rather than identifying edible foliage from resemblance to other carrot-family plants.
