This year we have had a good response from our 10 Alliums and of course now the flower heads are going to seed. I was wondering what to do, rather than simply cutting them off to discardor letting them seed, would a few 'self seed' to bulbs or just a few be retained to grow on next year? <alberthodgson@hotmail.co.uk>

You can also cut and dry the seed heads to use in a floral display.

They need cold weather then the warming of spring to get them to germinate. So let them self-seed and pick the seedlings next year: I would put them in a pot as they take 3-4 years to make a bulb large enough to flower.
