Plant an organic garden by choosing vegetables that thrive in your conditions, amending soil with compost, and selecting disease-resistant varieties. Feed plants naturally with well-rotted manure and organic materials. Rotate crops annually and avoid planting related plants in the same area to reduce disease buildup. Mulch the soil and remove dead foliage regularly to prevent disease spread. Water carefully and attract beneficial insects by planting flowers around the border. Follow these practices to enjoy a healthy, productive organic garden.
