Hardening off Snapdragons
Hello everybody -
Have a quick question about getting out Snaps for planting in the field this year.
My Snapdragons for cutting have been growing in a greenhouse and are a good 3 to 4 inches tall. The greenhouse has side curtains that open on good days so the plants have gotten a lot of fresh air and look really strong and healthy.
This next weeks weather won't go below freezing according to the report, I would like to get these plants outside into a cold frame as early as possible. How soon is the very earliest they can be planted into the ground outside? I know the seedlings can take a light freeze, but what if it gets really cold again? Will they be able to handle that? I do use seaweed as a foliar spray and I think it does help plants handle the cold better. Anyone with experience with planting out snaps early? Thank you for any help.
