Delphiniums

when do we cut these of and pop them in the cold greenhouse for the winter?

    As far as I know we cut them back then leave them in the ground - they're hardy perennials and are ok down to -15c.
    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    They are hardy enough. You just need to keep the slugs off the new shoots in Spring. I surround mine with crushed baked eggshells.
    You don't stop doing new things because you get old, you get old because you stop doing new things. <3
