I have a Blue Muffin that has been in for its second season now and no berries so I just bought a Little Joe as have read they will cross pollinate and get better berries but my little Joe bloomed before the Blue muffin. It's flowers are almost done and Blue Muffn still only has unopened buds. Don't they both have to be flowering at the same time for pollination and better berries? They have same sun exposure and about 40 feet apart. The Little Joe was just planted about six weeks ago.
