NO BLUEBERRIES!!!

We have a half dozen high-bush blueberries that have been producing vociferously for about 35 years. This year they had lots of blooms, but now there are 5 to 7 blue berries and 2 or 3 green ones. A late bush has more green berries. Might this be a symptom of age? Or have we hit the bee problem?????

Our blueberries are in Maine.

If there is a better forum for this, please advise.

TIA

I don't know anything about blueberries, but in mid to late May we had a very hard frost. Because of that all of my strawberry blossoms were killed and I had next to no strawberries. Apple orchards that are in my area have reported that they will have no Macintosh apples this year because of that frost. Apparently Macintosh apples bloom earlier than other varieties.

I hope this was your problem too. From what I was told we experienced something like a hundred year frost. If that was the cause we shouldn't have this problem for the rest of our lives.

I'm not sure but seems like I have read that blueberries do have a life span. I may just be thinking of the southern blueberry though and hope HelenVT is right about the frost.

Blooms but no fruit could be a pollination problem. Or maybe it was that 100 year frost. Either one will be well known in the Ag community.

Call your local Ag Extension office and see what they have to say. http://extension.umaine.edu/ Or check with your state Dept of Ag.

Ah, good to know about that 100 year frost... after unseasonably hot days in early spring. This may account for why we seemed to have no viburnum blossoms either! Or rhododendron. This is a vacation home, but we were there most weeks. But there was always the chance we just didn't look at the right time. Now I'm thinking it was the frost for the viburnum and rhodies. But since the blueberries had blossoms, it doesn't seem so likely. Right. I've seen bees around. What pollinates blueberries?

I have blueberry bushes that have been on this land for over 50 years and they are starting to peter-out. We bought 6 new ones this year to replace the old ones. I always but a variety...early season producers, mid-season and late season. This allows me to start picking the second week of July and I won't stop until the 1st-2nd week in Sept. ^_^

I did call the ag extension agent, on advice from here, and she said that we had 100 year record breaking killer frosts in both May and June. They were devestating with blueberries. We do have berries on our latest bearing bushes. We'd seen the flowers, but the frost must have happened later. This is our summer place, so we missed them.

This also explains why we saw no viburnum flowers.
