Mid March – mid May · 4 weeks before the last spring frost
Sow Seeds Outdoors
Sow thinly in drills where they are to grow. Sow 1 cm deep; soak seed overnight to speed germination.
14–28 days after “Sow Seeds Outdoors” · Late March – mid April
Check Germination
Seedlings should appear in 14–28 days. If sown outdoors, thin to 20 cm, rows 30 cm apart apart when big enough to handle.
21–35 days after “Check Germination” · Mid April – early May
Weed and Water
Hoe off weeds between rows and water in dry spells — even moisture gives better crops.
