File numbers explained:
AZ = U of A Publication
YC = Writtten for Yavapai County
BYG = The Backyard Gardener was a weekly Yavapai County, AZ newspaper column published from 1998 to 2021. The articles were written by University of Arizona Extension Agent Emeritus, Jeff Schalau. Those articles have been consolidated, updated and reformatted, and are available on this webpage with a designation of "BYG #". Ongoing research and changes in regulations will occur and inform best practices. Please use them accordingly and know that pesticides and legal statutes change over time. Horticultural practices also vary from region to region and state to state. For the most current horticultural and natural resource information in states other than Arizona, consult your local Cooperative Extension office.
