non-fruiting raspberries

Question

I have several raspberry plants which gave me a great crop last year. This year they are very tall (about 8 feet) and have no flowers or berries showing at all. I have always pruned them back to the ground in the early spring. I need to know what I am doing wrong or what I do need to do? Thanks.

Answer 1

It is probably getting too much nitrogen and too little phosphorus. Add some bone meal to increase phosphorus. This article will help:
