They will be fine in the greenhouse. I did mine a month ago and they are also in an unheated greenhouse.

Thanks SBG. I just love sweet peas and always ponder about which way is the best to display them. I usually end up letting them grow too tall and then struggle to pick the top ones.

hi if you pinch the tops out when there is at least 2/3 sets of leaves they wont grow as tall plus they bush out more at the bottom.other than that i will sell you a set of ladders haha just joking good luck.

Good tip kenny as I always have similar problems! Mine are now hardening off outside the greenhouse!

Ha thanks Kenny. At 5ft 2 inch I need a ladder for a lot of things.
Wow it appears I am way behind with my sowing. I need to get my gardening head in gear as I haven't done any sowing of my usual seeds as yet. It just seems so cold :-(

No Pdb..you have plenty of time. I always try to get a head start with annuals because our growing season is shorter here. And also because if I didnt sow seed in late Feb. I would probably just cry....the winter is just so long! Lol!

Youre welcome pdb.
