The sowing calendar month by month (outdoor & under cover)

Why follow a sowing calendar?

The success of a vegetable garden largely depends on the right time to sow. Too early, the seeds rot or freeze. Too late, the plants do not produce enough. A sowing calendar allows you to garden according to the seasons, optimize your harvests, and gain autonomy.

This guide accompanies you month by month, with the main species to sow in open ground or under cover (in pots, greenhouse, cold frame).
