EVERY PLANT HAS ITS MOMENT
When to plant Thyme?
The right month changes from one garden to another. Let’s find the season for your little green corner, starting with the climate and how you want to begin.
Thymus vulgaris
Roots come first
Let it settle in
For this crop we consider the first six weeks, without estimating a harvest date.
Sunlight
Sun or partial shade
Sun for part of the day is fine too.
Water
Moderate
Let the soil dry a little between waterings.

A SEASON TO BEGIN
A calendar for your garden.
Choose your location above to see the usually more favourable periods, with sowing and transplanting shown separately.
How to read the calendar
This is an estimate from historical climate, rather than a forecast for this year or a calendar for your variety. We compare three starting dates per month (5, 15 and 25) with cold and time to grow. A favourable month doesn’t guarantee that every day will be suitable. To decide about today, check the weather forecast too.
Air temperature records don’t measure the soil: check its warmth before sowing or planting. Indoor sowing assumes around 22 °C and plenty of light; we consider the climate at the later transplanting time. For perennials, garlic and artichokes we only assess establishment. Variety, chilling requirements, day length and local conditions need separate checks.

ADVICE WITH ROOTS
Nature doesn’t follow
the same calendar everywhere.
Your location helps us work out when to start.
Three things matter more than the month on the calendar.
The right place
Location and local climate: a mountain garden has a different rhythm from a seaside balcony.
The right moment
The coming days’ temperatures help us consider sprouting, cold and heat.
Time to grow
Recent climate records help us consider the time until harvest, or while a plant settles in.
