dirt loooks ashy.
My 4x4 raised garden has been in use for 5 years. Just now Oct. 2019 started to turn the soil over to add new garden soil because the old soil had fallen a couple of inches. When I turned the soil over the dirt looks like ash. It was a grayish white. Is this bad? what should I do?

Thank you for your question. It is impossible to identify a soil component without photos and, often, microscopic examination. Because your area soil has at least one fungus that is very harmful when inhaled, I suggest you take a sample (in a Ziplock bag) to your county Extension office: https://extension.arizona.edu/maricopa Good luck!
