How to Sow

Sow sweet pea seeds indoors in October for transplanting outdoors in spring, or direct sow outdoors from March to April.  In autumn, sow 3 seeds per 7.5cm (3″) pot at a depth of 1cm (1/2″) in free-draining, seed sowing compost. Place in a propagator or seal container inside a plastic bag at a temperature of 20-25C (68-77F) until germination which takes 10-21 days. Once germinated, grow sweet peas on in cooler conditions, before transferring to a cold frame for overwintering. Spring sowings can be made outdoors directly into drills at a depth of 2.5cm (1″), and a distance of 7.5cm (3″) apart. Pinch out the growing points of each stem once the second pair of leaves has opened to encourage bushier growth.
