raspberries and blueberries
I live near Green Bay, Wisconsin. I am trying to revitalize a huge wild raspberry patch by removing weeds, killing weed roots with Roundup and then fully fertizilizing the plants. They have not produced well in previous years. I hope they produce well this year. Now I want to start a blueberry patch. I have ample access to pine needles and plenty of acreage. How can I acidify the soil adequately for a productive blueberry crop?
