Arizona Master Gardener Manual
Arizona is home to one of the most unique climates in the contiguous U.S. when it comes to gardening, and as such it certainly merits having its own definitive guide. Enter the Arizona Master Gardener Manual (CALS Cooperative Extension-University of Arizona, 2016). Written by a volunteer group of Master Gardeners, this is the first bound copy widely available to the public. Covering everything from food production and pest management to lawn care and arboriculture, it will be an indispensable reference for years to come.
