What to do with my windowsill seedlings?

[Leaningtoweroflisa]

This year, I am trying to raise more flowers and plants from seed and I've made a bit of a start. However I'm just about out of windowsills!

Is it too cold ATM to move the bigger seedlings out into an unheated greenhouse?

There's a mixture of sweet peas, cosmos, tomatoes and annual flowers (which I cunningly did not label as I was sooo confident I would remember which was which)

I'd put the sweetpeas out as they are hardy. Maybe harden them off a bit by putting them out in the day and bringing them in at night for a few days.

agree with the sweet peas monty don was saying in his column that you shouldn't put tender seeds like tomato or courgette into an unheated greenhouse until mid may so I would hold off and pot on to bigger pots if you can. The family can live around it.. I am sure this won't be problematic if they are anything like as careful as mine

Whoops! Stupid work getting in the way of MN and gardening... Hadn't checked for replies and decided to whack them out there yesterday, as it was so nice here...

6 unhappy sun gold tomato seedlings today... Back on a windowsill for them! And hopefully they'll pull through.

The flower seedling otoh seem to be made of sterner stuff, I'll check them a bit later (toddler just down for nap and I need to grab lunch!)

Thanks for your timely advice x
