Triple Crown and Chester blackberry question
I have had trouble with these two type of blackberries. Both the Chester and Triple Crown are trailing type I am in zone 5. All but one of this years flouricanes that should fruit is showing any signs of life. I have 70' of trellis for these. The main shoot is is hard, grey and brittle? I am thinking that they were frozen out with the 2-3 weeks of below zero temps we had? Any thoughts? Is there any way to protect these varieties so they can produce. Two years ago we had a very late freeze that killed all of the blossoms. My production with these two types have been very frustrating! I am ready to dig them up and plant something different.
