I have what appears to be salt in the soil. I tested the pH level and it's way over 7-8. The lawn and juniper trees are dying. The color of the soil is white and looks like salt and doesn't dissolve. Please help!

If the pH is at 7, it is considered neutral, but anything over this is considered alkaline. Here is more information: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/alkaline-soil-plants.htm
