The advantage of sowing sweet peas in autumn is that you get a plant with a very well-developed root system that will romp away when you plant it out in the spring. To encourage root development you should pinch out the stem above the first set of proper leaves. I should have done this a bit earlier, but with such mild weather here they will be fine. In the next week I will transfer them to the coldframe so that they stay cool and concentrate on growing those roots.

The early October sowing of sweet peas is coming along nicely. I’ve followed Sarah Ravens advice and sown 2 plants to a pot so that they develop a really strong root system. I’ve decided to experiment with pinching out some plants and leaving others. Sweet pea specialist Roger Parsons says side shoots will develop naturally and pinching out is unnecessary. On the other hand the plants that Sarah Raven sends out are the bushiest sweet pea plants I’ve ever seen and the sweet peas in her garden always look magnificent.
I’m not always the world’s most efficient or organised gardener, but there are certain things that I always try to do. One of these is to sow my saved sweet pea seed in Roottrainers and deep pots in October. They have germinated well and are now in the coldframe where they should develop a good root system over winter, ready for pinching out in the spring to encourage bushy growth.
