We had several old evergreens removed maybe 8 yrs ago. They ground up the roots and now I'm trying to plant iris, lilies, cornflowers, etc. in the ground and they are not doing well. How should I treat the soil? Is it lacking lime?

I would actually recommend that you have your soil tested. This would be the best way to find out for certain what, if any, nutrients might be missing that could be causing the problem. Then you can find a suitable fertilizer based on that.
