Hoping that the worst is over, I removed the bags from my citrus and loquats to take a look. (But left Christmas lights attached just in case - since one year it snowed on April 1st!)
My unprotected low was 7F, the second year in a row with abnormally low temps for zone 8a. With a polycarbonate roof, lights, and bag covering, my protected low was 24F.
Varying response from citrus: Sudachi fared the worst and it looks like plant will lose its leaves.
Yuzu looked fine with new growth.
And, what a surprise, Hamlin managed to put out a little growth and held on to its one orange.
Loquats had varying degrees of tip burn.
I know you know that folks outside this forum think we’re a bit crazy!!
I’d love to hear others’ results.
