Where to Sow
September sowings in flowering site 2cm (1") deep. Later sowings in pots, five seeds in each. October and November sowings in a cold frame. January and February sowings in a heated glasshouse. March sowings in a cold frame. April sowings direct in flowering site.
What to do Next
Glasshouse raised sweet pea seedlings should be hardened off during March. Plant out pot grown seedlings in the flowering site 15cm (6") apart in April. Thin direct sown seedlings to 10cm (4") apart. Pick flowers regularly to encourage new growth.
Maturity
May to August
Handy Tip
Provide sturdy support for plants. After a good rain a mature plant will be very heavy.
