What to sow and plant in August
38 crops on the list have something to do in August 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.
This month normally sits between the last spring frost and the first autumn one, so tender crops can be outside. Heat, water supply and disease pressure become the limits instead of cold.
Sow direct outdoors(11)
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(3)
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.
Ready to harvest(32)
An approximate window from the sowing dates above. Each crop page carries the physical cue that beats any date.
