By Today temperatures in the SF Bay Area, Santa Clara region, peaked at 101 in the shade. Temps reached 108 degrees. For my bonsai friends around the bay, remember to cool down those pots. You may have to water twice a day in some areas of full sun. Humidity is only 14% where I am so things are drying out fast. Soil temperatures on my black pine pot was over 120 degrees before watering.
Take steps protect your trees. The tree below, the olives, are loving the hot temps and is drought resistant. After watering today the leave are busting out every where and dark green. They will enjoy the watering and humidity I introduced much more.
