Garden Planning Tips

Use this area calculator to plan your garden layout. For vegetable gardens, consider companion planting and crop rotation. Leave adequate space between plants for air circulation and growth. Square foot gardening divides beds into 1-foot grids – perfect for intensive planting. Remember to account for pathways (at least 18-24 inches) between beds for easy access. For irrigation planning, knowing your exact area helps determine water needs.
