Blackberry 2014 update...
The other thread was getting too long.
Please post pictures when you see your first blooms, I like to see how long it takes for the blooms and ripening in the various cultivars, here we can compare them nicely!
As said before, mine out in the country,...perhaps a low zone 3, my Chester died completely down, year 3, [unprotected], the other plant right beside, Balsor's Black, same age, had two canes alive, these should produce fruits,..it's just now will they ripen before snow falls?
Got rid of the Chester, not totally,... shooting up from below, I made 4 babies and could go soon for adoption to the warm city!
