Companion planting is a time-tested method that uses the natural properties of certain plants to repel pests and attract beneficial insects. By strategically placing plants together, you can create a natural defense system for your garden.
Marigolds release compounds that deter nematodes and many flying insects. Plant them around tomatoes, peppers, and other vegetables to provide natural protection. Basil repels aphids and mosquitoes while enhancing the flavor of nearby tomatoes.
Nasturtiums attract aphids away from your main crops, acting as a trap crop. Chives and garlic help repel Japanese beetles and other pests. Research which companion plants work best for your specific crops and pest problems.
