so far we been to 39 with no cover but no frost happened either. looking at that or lower next weekend we are dialing in our tarp tech for the fall season....mom nature says its time.
A hard frost will but normal frosts will not. Mine go through 1 to 2 frosts every year and as long as they are well watered they bounce right back as soon as the sun comes up.
Yes, I’ve had some plants go thru frosts. Wake up in the morn, go check the girls and see them covered with a layer of frost. Alls fine tho once the sun comes back out!!
