Hello, I purchased 5, three year old Anne raspberry plants in 2013 which makes them now, 6 years old. They were purchased from Berries Unlimited and came with a certificate certifying that they were inspected by the Arkansas State Plant Board and were found to be "apparently free of injurious pest and plant diseases". The five plants are in a 2 foot by 11 foot raised bed. The ph is in the 6.5 -6.8 range. We cut the plants down in March so that we get one fall crop The plants started out nice and green in the Spring. I did not apply fertilizer until May 20 when I added 2 cups of fertilizer (which consisted of 2 parts blood meal, 1.5 parts bone meal and 6 parts greensand. On June 5, I added 1 cup of worm castings. The plants were not responding, so on July 3rd, I added another 2 cups of fertilizer (2 parts blood meal, 1.5 parts bone meal and 6 parts greensand). It is now August 31 and we have harvested a total of 3 cups of berries and the leaves are 50-60% dead. Can you help? By way, I have 5 blackberry plants in a 2 foot by 11 foot raised bed adjacent to the Anne raspberries and they are healthy and very productive. They yield approximately 12 quarts of berries each year. Thanks,
