amending my heavy clay soil
I have heavy clay that has been under a landscaping cloth and mulch for years, how can I best amend this soil and prepare it for Xeriscape plants and other landscaping plants? I also would like to know what Bearded Iris need to do well in this climate.

The best way to amend a clay soil is by adding compost.
This link will give you information on adding compost to your soil: http://http//planttalk.colostate.edu/topics/soils-amendments-composting/1614-composting-using/
For additional information about using soil amendments, here is another link with good information: http://http//extension.colostate.edu/topic-areas/yard-garden/choosing-a-soil-amendment/
The extension office doesn't have information about which types of Iris grow well in Colorado, However there are many types that do very well here. I'd suggest talking to some of the local nurseries, especially those that specialize in Iris.
I hope this information helps, please feel free to contact us again if you have more questions.
