non-fruiting raspberries

Zone 7-8 | janegardens added on July 13, 2012 | Answered

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.

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