There are a few reasons why your blackberries are not developing correctly. First, it’s always a good idea to do a soil test to see if there are any nutrient deficiencies, despite having given the soil rose food. Second, you need pollinators (native bees, european honey bees, flies, moths, butterflies) to pollinate your blackberry bushes. If you use any herbicides or pesticides, discontinue their use to make sure you aren’t hurting the pollinators. Lastly, your blackberry bushes may have become infected with a fungal disease, which can affect the production of fruit without showing any other outward signs. Unfortunately, there are no cures for these diseases, so wait until next year to see if your berry production is simply having an off year. We hope this helps!
