I have ordered some delphinium plug plants for my south facing border Glorious flowers and very excited . Can i plant them out in the border in the Autumn and overwinter them? Dont have a greenhouse sadly. If not where shall I look after them until spring? Thank you .
I am raising a second lot of delphinium plugs as I made the mistake of putting the first batch in the ground and the slugs got them all I don't have a greenhouse and so was going to over winter them in my shed (it has a window). If they survive, I might try them in containers as I couldn't bear to see them decimated again!
