Raspberry - primocane ripening times
This spring I planted two rows of raspberries (52 ft each).
One row is Boyne (hardy florocane) and the other is Autumn Britten. There have been so many favorable comments on this forum about "Caroline" and "Anne" that I would like to add another row with one of them. My problem is my Autumn Britten have only ripened about 1/3 of their potential crop an it could frost any day here (150 miles north of Minneapolis). My berry book indicates that the above varieties mature later than Autumn Britten.
(1) Is there a chance that the Autumn Britten are maturing slower than normal because they were just planted this spring and they are still getting established? Canes made it to about 4ft and are quite lush. They got plenty of water, aged manure, and mulch. After getting established, do you think Anne or Caroline could ripen in time to be worthwile in Z 3/4?
(2) Autumn Britten - Pronounced "Brite-en" or "Brit-ten"?
(3) Each row was planted with 25 bare root plants. 3 of the Boyne plants had some berries this summer. Is this possible or are those mis-labeled primocanes?
