The University of California has put 63 years worth of its journal California Agriculture online for convenient downloading at californiaagriculture.ucanr.org. There’s plenty of detailed (peer reviewed!) nuggets for the home gardener between the pages of this scientific journal. Make sure to check out the article and video of UC Berkeley entomologist Gordon Frankie explaining what kinds of plants are best for attracting bees in your urban garden.
Thanks to Los Angeles County Master Gardener Coordinator Yvonne Savio for the tip.
