Where to Sow

September sowings in flowering site 2cm (3/4") deep. Later sowings in pots 5 seeds in each. October and November sowings in a cold frame. January sowings in a heated glasshouse. March sowings in a cold frame. April sowings direct to flowering site.   

What to do Next

Sweet pea seelings raised in a glasshouse should be hardened off during March. Plant out the pot grown seedlings direct in the flowering site at 15cm (6") apart in April. Thin direct sown seedlings to 10cm (4") apart. Pick flowers regularly to encourage new growth.

Handy Tip

Provide sturdy supports for plants. After a good rain, a mature plant will be heavy.
