How cold is too cold?

[MrsBertBibby]

I have young plants outside, It's forecast 5 degrees tonight.

Should I be putting the plastic covers on the protect, or is that OK?

We're talking snapdragons type seedlings.

I'd cover to be on the safe side
5 degrees is borderline.
Better to be safe than sorry.

I guess you're right. Covers on.

Yes I've tucked young things up as best I can .

And another here who'll be cleaning tomorrow .

Wow, you were right! Both bird baths iced over this morning!
