Plant seed potatoes in early spring, spacing them 12 inches apart and 4 inches deep. As they grow, mound soil around the stems to encourage more tuber formation, which also helps prevent erosion in blueberry beds. The deep roots improve drainage, reducing waterlogged stress on both crops.

This pairing is perfect for gardeners with limited space—potatoes grow well in containers or raised beds alongside blueberries. Plus, you’ll harvest nutrient-rich tubers while keeping your berry bushes happy and healthy. 🌱

Its large, broad leaves create a natural shade canopy, protecting delicate berry plants from the harsh afternoon sun.
