Raspberries Spraying required.
This is what they recommend but I am going to spray with Ortho's new spray called "Garden Disease Control" that is extremely effective. It stops and prevents over 130 different diseases. I spray all my garden and flowering plants, my vegetables, and my trees with it. The results are fantastic. Tip #1A is spray with Ortho "Garden Disease Control" often. I do it once every 2 weeks. For insects I will be using Ortho's new Bug Be Gone spray.
