Plant Spacing Tips

Proper plant spacing is essential for healthy growth. Too close and plants compete for nutrients and light, increasing disease risk. Too far apart wastes valuable garden space. Square foot gardening divides beds into 1-foot squares – plant 1, 4, 9, or 16 per square depending on size. Triangular spacing can fit up to 15% more plants than grid spacing. Always check seed packets for variety-specific recommendations.
