Can companion planting really help reduce harmful insect populations in my garden?
Companion planting is a proven technique for discouraging insects in the garden. In this age of agricultural-chemical innovations, it’s easy to forget that just 50 years ago farmers used companion planting techniques for pest control instead of toxic chemicals. Plants such as marigolds release biochemical scents both from its roots and leaves that drive off some potential garden pests. Try planting them in between garden rows for a powerful and pretty garden companion. Other plants can repel specific pests, such as beetles, nematodes, or even moles.
