What to sow and plant in March
34 crops on the list have something to do in March at 50.0°. These dates are not a fixed calendar: they are calculated from the estimated last spring frost for this latitude, so they move with your location.
Frost is still likely at this latitude, so tender crops belong under cover. Anything sown outdoors now must be hardy enough to take a freeze, or protected on clear nights.
Sow under cover(15)
Started on a windowsill, in a propagator or in a greenhouse, to gain weeks the outdoor season does not have.

Sow direct outdoors(3)
Sown where the crop will grow. Soil temperature decides this more than the calendar does, so check the figure on each crop page before sowing.
Plant out(16)
Moved from pots to their final position. Harden plants off over a week first; a tender crop planted into cold soil stalls rather than grows.
