Answer: Most likely, your plants were suffering from some sort of disease. Potatoes are succeptible to many fungal and some bacterial diseases. To reduce the problem, rotate them to a different bed each year. After three years, you can safely plant them next to the raspberries again, so long as the raspberries don't crowd or shade the bed. Space hills far enough apart so air can circulate and keep the leaves dry, since fungal and bacterial diseases need moisture to grow. Mulch the soil with straw after hilling the potatoes to provide a barrier between soil-borne spores and leaves.<br><br>Although potatoes aren't heavy feeders, they may be lacking nutrients. Mix compost or balanced, slow release fertilizer (5-5-5) with the soil before planting, and for maximum yields, side-dress or foliar feed plants when they bloom. If you want to know which nutrients may be lacking, contact UVM Plant & Soil Science (656-2630) for a soil test kit. I hope this helps!
