Blackberry Plant Cold Weather Protection
It appears that I picked a good winter to test blackberry cold hardiness. As many have noted in the "Coldest air in many years on its way?" thread, it appears that my Northern KY location will test my it's hardiness limit of -10F in a couple of days. I have covered my trailing blackberries earlier in the year and increased their protection recently with a mylar emergency blanket under the 1.5oz row cover. Snow now covers them and they seems like they should be protected in the severe cold spell. Ironically, it is my erect and semi-erect varieties that need protection now. I'm considering spaying them down with water to provide an ice shield for the cold. Do you think that will work when the temperature drops into the negative double digits?
