if you have the free time in the next few mornings ive heard if you hose the trees down with water it may help keep the frost from setting in. never tried it just an idea i heard. anyone know if this works?
The orange orchards in Florida turn on the water sprinklers. The theory being it takes more energy to lower the temperature of the water on tree buds/branches to create the damage a frost would do. I guess if you wanted to get up about 4 AM and set out the sprinklers it should help. Actually, given the number of buds on my pear and apple trees, this might not be a bad thing for me to do this evening.
I would seriously consider a couple charcoal grills around that tree.
