I suspect that this is related to the same issue as your Spirea. Clay soil is notorious for being nutrient rich, but largely unavailable. If you can work some organic material in without disturbing all of your plants and shrubs, then this would be ideal. if not, then worms will be your best friends in this situation. I have the same problem in my area, and I solved the issue with these methods. Many of my projects from the mycology lab end up in the yard and garden, as well. Mushrooms and fungi are the BEST at remediating soil. (As long as you avoid putting certain ones out, such as Armillaria.)
