As an inveterate season-jumper, I’ve got a few batches of cabbage and lettuce set out. Now comes a really hard freeze - down to 20.
So I’ve got agribon row covers and black plastic. Wondering - would it be best to double up on the agribon, or cover agribon with plastic - as I’m inclined
I would use double agribon and above it plastic or tarp. It will protect from wind and keep soil warmth inside. Just don’t forget to take plastic/tarp off when it’s day time and weather warms up. But best if you make some kind of frame for the cover. Lettuce, for example freezes and unfreezes just fine, unless you touch it frozen, so idea is to avoid cover touching plants. if it is not many plants you may use buckets/baskets for each and cover on top of them.
Will probably get down to about 28 tonight. There are peaches in bloom. Some may make it through.
My bigger concern is the enduring cool weather and dry weather we have been having. We’ll have four days a week where it rains, but not one of those days gets more than a couple hundredths of an inch!
