Companion Planting and Rotation for the Vegetable Garden, Darrin Morgan of Shonnard's Nursery
Improve yields with less work. Inter-planting and companion planting use the natural aspects of some plants to repel insects and diseases, balance nutrient use, and otherwise encourage other plants to grow. Crop rotation differs from companion planting in some respects, but uses many of the same principles to produce higher crop yields with few pests and disease problems and nutrient inputs.
Darren grew up gardening and farming in the northern Willamette Valley. He has worked at Shonnard’s, in both landscape and nursery divisions, for 24 years. He enjoys drawing, writing and backpacking, as well as gardening.
