When to plant mint in Paris

These come from the ERA5 reanalysis on a roughly 9 km grid, so they describe the area rather than your plot. A hollow, a frost pocket or an exposed site regularly runs several degrees colder, so use the cautious date for a decision you cannot undo.

The cautious column is calculated from the latest frost recorded in the period (30 Apr). Use it for tender crops you cannot re-sow.

What can move the date
Always plant it in a pot, even if the pot goes in the ground — the runners will otherwise colonise a whole bed within two seasons. Divide and repot every second spring or it exhausts itself.
