Tuberous parsley: Sowing, planting and harvest calendar
How do you sow tuberous parsley outdoors?
Sow root parsley directly where it will grow in spring, at a time suited to your climate and the seed packet instructions. Choose sun or partial shade and fertile, loose soil that stays moist but drains well. Prepare a fine seedbed, removing competing weeds and large obstacles that could interfere with root development. Avoid working waterlogged soil.
Spread the seeds without crowding them and cover lightly, following the depth recommended for your variety. Water gently so that the seeds are not displaced. Mark the row: germination can take several weeks and the first seedlings remain small. While you wait, check the surface moisture regularly and prevent the seedbed from drying out completely, without keeping it saturated.
Do not mistake slow germination for immediate failure or pull out young seedlings while weeding. Direct sowing lets the roots develop without being moved. Once the plants are sturdy enough and easy to identify, thin them gradually; the maintenance calendar describes the spacing to retain. Sowing time will also influence when the roots are ready for harvest later in the season.
