How to Grow Sweet Pea Giant Spencer Wave Mix Seeds

Sow Sweet Pea Giant Spencer Wave Mix Seeds in September or October for overwintering, or make later sowings in pots or deep modules. JustSeed's existing variety guidance recommends sowing approximately 2cm deep, with two seeds per deep module or around five seeds per pot. JustSeed

Place autumn-sown pots or modules in a cold frame or unheated greenhouse over winter. Sweet Peas benefit from deep containers such as root trainers because they develop a substantial root system.

Grow young plants in cool, bright conditions and plant them into their flowering position when conditions are suitable.

Choose a sunny position with moist, fertile, well-drained soil and provide sturdy support before the plants begin vigorous climbing growth. JustSeed

Tie young stems loosely to their supports where necessary until the tendrils begin holding the plants securely.

Sweet Pea Growing Tips

Provide tall, sturdy supports before planting.

Keep the soil consistently moist during dry weather.

Pick flowers regularly for bouquets to encourage further blooms.

Remove faded flowers before seed pods develop if you want to prolong flowering.

Pinching young plants can encourage bushier growth and additional flowering stems. Hampshire Seed Company

Grow in fertile soil and feed during the flowering period where necessary.
