Budbreak on this first day of spring appears to be holding off due to the cooler temperatures we have been experiencing in NC. These pictures were taken at the Sandhills Research Station last week by my student, CM Bradish. Only Prime-Ark 45 is showing any signs of green leaves.
I was looking at the Team Rubus blog post from last year and see that in March (10th), at the CEFS pruning demonstration, blackberry buds were a bit tighter, but not much. http://teamrubus.blogspot.com/2012/03/pruning-workshop-at-center-for.html
No budbreak at this time is a good thing. We have accumulated plenty of chilling and once it gets warm, these buds will grow quickly. We don't need a repeat of 12 April 2012 when flower buds were killed by low temperatures. http://teamrubus.blogspot.com/2012/04/freeze-2012-field-visits.html
If you have time to take some pictures and send them to me (labeled with variety and date photo taken), it would be great to have a snapshot in time from various locations, to see how the crop is developing.
