Do you harden off?

Hi All,

I have a porch which I have been growing seedling in.

I grew lupins in August, the seedlings came through the winter and are thriving. They have been potted up and the window has been left open all day and night for the past two weeks.

Do you guys think I need to harden off the plants (which are now filling polystyrene pots).

    For at least a week.

    Yes indeed.  Leave them outside in the daytime - just for a warm hour or two at first, if we ever get any - and evenentually on a warm night.  If they've been in a porch with the window open that's a good start.

  • Hi, yes. I did for 2 weeks last year and noticed the difference, stronger plants and leaves etc.

    Bit early to put them out anyway, I'm Surrey and we had snow yest and frost this morning, I'm waiting until end of May before planting out image

    Ive never knowingly hardened off my seedlings or plants, I sow them inside, once they germinate I then move them into the greenhouse until its warm outside and then just put them out. So I guess I could say that is hardening them off isn't it?
