Amy Jo Detweiler, a member of the Deschutes County OSU Horticulture Staff, has co-authored a publication entitled, Growing Vegetables in Central Oregon. You may find this guide helpful if you are planning a vegetable garden. Seed selection and starting is discussed on page 10-11.

“This guide provides region-specific tips and techniques for more successful vegetable gardens, including topics such as site selection, soil amendment and preparation, irrigation, weed and pest management, seed starting, direct seeding, and season extension. It also contains planting guides for over thirty vegetables commonly grown in Central Oregon.”
