Raspberries produce no blossoms

Raspberry    None Given

For the last two years our raspberry plants have produced very few blossoms or fruit and have turned yellow about mid-July. Is this a disease? A nutrient deficiency?

Could you provide an image? This would make identification of the problem much easier. Thanks!

This could be a disease or it could be that the variety you have planted is not adapting well to the conditions in your garden/area. What variety did you plant and where are you located? As much detail as possible will help people answer. As Marcel says, images are very helpful too. Thanks!

Has Marcel said, a picture would really help... It might be a virus, do the leaves seem OK?

A soil test is the best way to check on nutrient deficiency and to make sure the soil pH is right. Look into this through your state's land grant university/extension service or state department of agriculture.

Do they produce one crop a year or two? If they bear one crop then you'll need to thin out all the brown canes every fall, if you have two crops then you just need to mow them down after your second crop. Pruning will make sure that your patch isn't filled with non-productive canes and aid with disease control by allowing air to circulate around the canes. Of course without a pic I'm just guessing.

If it's a young planting that's never fruited well, another possibility could be lack of light. To fruit abundantly, raspberries need a location the receives full sun. They also need rich, well-drained (but never waterlogged) soil that receives abundant water.

As J.D. notes above, it's important to understand how to thin and prune the variety you've planted.
