Once you get about four true leaves, not the cotyledon leaves; you can pinch out the growing tip to make them bushier and produce more. You only have to do this once; sometimes I forget and don't pinch them; they still vine out well anyway.

Normally they are sown in October but take a look at all the info here http://www.gardenaction.co.uk/garden_diary/garden_mini_project_october_1_sweet_pea.asp for what to do now
