When can sweet peas be planted outside?
Likewise, what month do you plant sweet peas?
Sow your sweet peas seeds anytime from October until March, two seeds to a pot. You can sow your sweet pea seeds in March but growing sweet peas over winter will produce stronger, more robust plants.
Similarly, should I soak sweet pea seeds? Many people recommend soaking sweet pea seeds overnight before sowing to help them germinate. This is because some varieties have a hard outer shell. However, others suggest that soaking may lead to weaker plants. Generally, sweet peas should germinate fine without any treatment.
Likewise, what to do with sweet peas when finished flowering?
Cutting back. Cut perennial Lathyrus back to ground level in autumn or, preferably, leave the cutting back until February so the dead stems provide cover for wildlife in winter. Simply pull out and compost annual sweet peas once flowering has finished at the end of summer. In hot, dry seasons this might be a bit sooner
Do Sweet peas need full sun?
Conditions Sweet peas grow in full sun to partial shade and require rich, well-drained soil. Sweet peas are sometimes troubled by birds, slugs, snails, aphids, and thrips. Propagation New plants should be grown from seed.
