Apologies if this has already been discussed, but internet searches have proved a bit fruitless.
I have some Iris growing in my front garden that now have seed pods well formed and I would like to try to grow some more from seed. I'm not sure what variety of Iris they are, I'm assuming a fairly bog standard variety from the garden centre, they were there when I moved in. I have a heavy clay soil and the flowers were bluey/purple. Theyt put on a good show this year and I want to get some more around both front and back gardens.
I want to do 2 things, firstly is to divide the clump that I have so that I can spread them along the front garden border and also into the back garden. How best is it to do that and when should I?
Secondly, the seed pods are well formed, although still very green. When is it best to collect the seed? and how best is it to sow the seed in pots for later planting out.
