I live in the Central Valley of California where we get 100+ degree F weather (92 d expected today 4/26). My potted seedlings (this year's crop) sit under the canopy of an enormous japanese maple. I'm looking for advice on watering practices. Will drip irrigation work alone? or do I need to setup a mist system for the hotter parts of the day, to complement a drip system. How often to water in such hot temperatures? I've read Vertrees, however, he does not provide climate specific recommendations. Thanks in advance!
