Whew, it’s a hot one! Wondering what it feels like to be a plant? Here is a very unscientific comparison of what a plant surrounded by decomposed granite feels like vs mulch. As you can see the temperature is much hotter than we record 6′ off the ground and in the shade. This particular day the forecast high was 108. The temperature of the ground covered with granite is approaching 130 degrees, while the mulch while still very warm is 12 degrees cooler. Twelve degrees on top of the soil would be even a bigger difference under surface a few inches. If you plants look a little heat stressed, now you know why and one of the first things you should do is get the d.g. out of the way and replace it with some kind of organic mulch or compost!
