Sow seeds indoors in February or March, like I say, they need warmth to get going. Pop them into small pots or modules, about 1cm deep. A propagator or a warm spot near a radiator, aiming for 18-25°C, is ideal to kick them off. If you've got grow lights, even better, keeps 'em from getting leggy. You can always pick up plug plants later if you miss this window, mind. Just remember, these aren't for direct sowing outside, not up here in the North East anyway.

Once they've got a couple of true leaves, prick them out gently into their own 9cm pots. Keep 'em warm, minimum 15°C, they're not keen on the cold. Don't rush them outside, they're tender things. Wait until all danger of frost is gone, usually mid to late May up here, and harden them off proper for a week or two. Then they can go into the greenhouse, poly tunnel, or a very sheltered spot outside. Give 'em about 45-60cm spacing and they'll need some support, like a cane, as they grow. Some varieties are great for containers too, especially if your space is a bit tight.
