My trees seem to have made it thru the freeze OK, very few curled or yellow leaves. I talked to the McKenzie's in South Carolina the other day and they don't know what the final damage is going to be of their orchards. They hit 7 degrees a couple of nights in South Carolina, I don't know what kind of protection their orchards had. They said a lot of people have good luck putting their Satsumas in large pots with wheels so they can either be brought inside a carport or on the porch on the worst of winter nights. I wonder what kind of protection you would get if you misted the trees and let them have a covering of ice.
I have got to get some fertilizer, won't be long before they will need a dose.
