For slightly earlier flowering plants, seeds can be sown in pots from mid-October to November and then over-wintered in a cold frame or cold greenhouse. However, most growers prefer to sow seeds indoors in 7.5cm pots from January to April.

For best results use a rich peat based seed compost. Fill the pots to within 2cm of the top, and then lightly press down to firm the compost. Using your finger or a dibber, make 2-3 evenly spaced holes approximately 1cm deep and place I seed into each. Lightly cover with seed compost and apply water using a watering with a rose attachment.

Cover the pots with polythene or glass to retain moisture and then leave to germinate, which if a temperature of 15-20c is maintained, should take 7-14 days. It will take a little longer in a colder temperature, however check pots daily.

Some growers prefer to soak the seeds or chip them prior to sowing but this is not considered necessary. When the young plants are about 10cm high you can pinch out the growing tips to encourage plenty of side shoots resulting in bushy plants.

Beds or containers; If the plants are to be grown outdoors in beds then the soil should be well prepared at least 4 weeks in advance ensuring adequate amounts of organic matter is incorporated. Sweet Peas prefer a well-drained soil and a sunny to partial shade position.

Plants should be hardened off prior to planting out into their permanent positions, 20cm-30cm apart, from May onwards and after all danger of frost has passed. After planting, water in and ensure there is suitable support for the plants. Canes, netting and trellis are all ideal for supporting Sweet Peas.   

Sweet Peas also grow well in large pots or containers, which can be placed around the garden or patio and decked areas. Use a proprietary potting compost and transplant from the 7.5cm pots into minimum 18cm to 25cm pot or equivalent container sizes.

The addition of a slow release fertiliser to the compost will benefit plants over the long summer months, ensuring they receive adequate supplies of Nitrogen, Phosphorus and Potassium. Supports can be placed inside the pots or containers, or the plants can be trained over netting or trellis.
