The heat here is NOTHING like the heat in that hellhole Spokane, and it cools off at night so the heat is not that many hours per day and there is dew. I am just barely into the coast range so it is 10 degrees cooler than on the other side of the hill. Although these did well in that hellhole Spokane which killed many of the western species and all of the orientals unless they were in the full shade. But they cannot take hot, wet soil so I do not water and there is no mulch anymore so they are dying from hot, cracked soil. And slug invasions into that soil.
