Two of my blueberry variety bushes , one unknown and two bluecrops have a problem with their flower buds. Their buds started swelling very early in the winter ,like december but stayed closed, just had plumped up. Now the one unknown had several flower buds ,and when inspecting them I found out they are dead/ brown inside ....the bluecrops also have fully dead buds, but the majority of them just have their bracts dried out, but the will tiny flower dots between them seem alive .....is this cold burn ?? I really think this is due to the waking up and plumping before the coldest of the winter, the others which had not plumped in the fall are as regular starting to do it now and have fine looking all green flower buds .
How do I prevent them from waking so early ?? They are planted in the ground so I think if this becomes a regular basis happening I will have to grow them in containers and bring them in a basement for winter.....
I will provide pics later this day
