Stage BBCH Notes
Sowing 0 Direct sow 2-3 weeks before the last frost date, seeds 1/4-1/2in deep; germinates in 7-14 days (Seasonal Gardening).
Rapid leaf growth 3 Grows rapidly to 3-4ft; water freely during dry weather to avoid bolting (Seasonal Gardening, RHS).
Flowering 6 Small, insignificant clusters of reddish-green flowers borne in summer (RHS).
Harvest and cut-back 8 Harvest young, tender leaves as a spinach substitute; cut back after flowering to prolong leaf production (RHS, Seasonal Gardening).

Storage

Best used fresh

Plan next season before the problems start

Almost everything on this page resolves to your own frost dates rather than the calendar — the last spring frost moves by roughly two months between zone 3 and zone 10. The USA Garden Planner works from your zone so the timing is already decided before the season starts.
