Hi this is my first post on this forum but I have looked in before.

I planted 20 plants of Autumn Bliss raspberries in early Spring 2007, I bought them from Blackmoor Nurseries.  They established very well last year and produced flowers but no fruit, I thought that it was because they had not been established long enough.  This year they have produced masses of vigourous canes 1.5 - 1.8 metres high and have been flowering profusely for the last two monthes but not a single flower has set fruit.  There is no obvious sign of any deficiencies.  There are masses of bees visiting the flowers so pollination should not be an issue.

Has anyone any ideas what might be the problem?

All the best,

Chris

I don't really have much of a clue at the mo. other than pruning problem, possibly. Did you prune at all? As old canes will fruit on and of most year, if you leave them in but don't seem to be too successful at fruiting well. New canes shall start producing nowish, so hopefully, you shall see an improvement, unless you thinned or pruned them out.

Otherwise, as said. :?  :shock:

I pruned the canes down to the ground during last winter so all of the canes are new growth this year.  The problem is that the flowers just do not set fruit, there are plenty of flowers that atttract insects a plenty but they just dry up after a few days.  It's a real mystery.:scratch:

I wondered whether the material acquired from the nursery is sterile but I would have thought that there would then be a lot of other people with the same problem.

Drying up, hooh. Any chance you could post some photos of the plants, that all of their parts can be seen? Just as DD aptly put it, saves asking loads and loads of questions and also saves getting side tracked on the wrong train.

I suppose they are not dry. The nursery is good and I would not expect getting sterile plants from them, of course things happen... First year is all right, but second is dodgie. Saying that, I had one cane of me dozen planted that looked dead for 2 seasons and then... You think I'm telling a lie, sounds it, but I'm not.

How did you plant them, a bit of history might help, too.

Trying again, I hope that this works this time!

This photo was taken last week

Not for me...

I've edited the link to the image, it seems to be working now.

Any thoughts would be appreciated.

Can't help with your problem but my Mum's autumn raspberries (which produced plenty of fruit last year) have hardly any fruits on this year!  :?

[love-my-plot]

I know you said there are plenty of bees around the plant ... but it does look like the fruit hasn't been pollenated. Just guessing here, though, so could be wrong!

[gobs]

Now I might be imagining things, but in the top, browning flowers there seem to be some green druplets of some fruitlet - nothing like a raspberry -, can you confirm that? Does anybody else see them?

If that's so, pollination happens and they are not sterile.

Either the pollination is inadaquate or you can have a virus. Or something else, I do not know about...

I can't see sign of anything in that photo that would have such consequences but you should check for larvae and bugs in flowers too, just to make sure.

Was there any improvement in your plants this year - did you get any raspberries?

I have the same problem with my raspberry plant on my roof terrace in London. These are in a large planter with plenty of compost, feed and water. Other plants seems fine and are fruiting, but is no fruit on the raspberry plant. The plant produced many flowers, but no fruit, now these heads have dried up. Very similar to the photo above. I did see some berries starting to form, but only a couple. Any more ideas?

Thanks!
si - new here

Have you had a lot of rain during the flowering period?  I find that this has a bad effect on fruiting.

[Chris Ivin]

I dug them up last winter, never did get any fruit.  I planted a new variety in their place (name has deserted me at the moment), plenty of fruit now!!!

It MIGHT be stamen blight which affects rasps and blackberries (carried by spores.) Or as someone else said....maybe you're watering too much and the blossom is rotting/mildewing. I've got "Polka" which is bred from "Autumn Bliss" and they like it quite dry.

I suspect it is drought. No rain here for a month and you are further south. Blackberries in the hedges look the same.
