Espalier – An Artistry of Plant Training and Mastery , Mary Van Agtmael
To espalier is when we attempt to control the nature of a plant by structuring its growth pattern with the use of rigid form. It works better than training our children, spouses or pets, according to Mary.
After being raised on a farm and then gardening on her own property, Mary took the MG course in Linn/Benton Counties in 2007. She realized she really didn’t know plants and gardening techniques. Later, Mary discovered espaliering in growing grapes. Now she teaches people how to espalier so that anyone can grow a tree fruit.

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.
