| 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? |

| I'm in 6a/5b and I don't plan to protect them at all. If they don't make it, that is fine. i don't want to have to mess with them every year. It's a great year to see what can make it. If not I will try others or replace them with raspberries which never seem to mind the weather. I'm not sure if what you suggest will work? the only way I could do that is with my tank sprayer, as I would not want to hook the hose up in this weather. See what others say... |

| I think that blackberries that are good for zone 5 or 6 will be okay. I set out an apache and a natchez this fall and this morning we have 14 degrees.. |

| I have a Natchez, Triple Crown, Chester, and Navaho, unprotected and it was -3 yesterday morning. i'll report back in the spring. It's going to be -10 Monday night. I also have others and will report any problems. One is protected The Wyeberry. It's buried under straw. I left one cane exposed, just to see what happens. It's a rare plant so i decided to protect it. |

| So the weather didn’t cooperate with my plan. Freezing temperatures were delayed until later in the evening, so I couldn’t spray the plants with water before the deep freeze arrived. There was some rain yesterday, so hopefully it helped provide an icy cover … but on the downside, the rain melted much of the snow that was protecting my trailing blackberries. At -4F now and at least -10F tonight, this should be a good test of blackberry and raspberry cold hardiness. |
