Hi Kat, Are you familiar with the Iowa windbreak cost share program? I have used it twice for the north and west sides of my acerage. They have all your soil types already, and give excellent recommendations on types of shrubs or trees to plant. If you use it as a wind break and follow thier rules(which are good ones) they will pay a good chunk of the plant price. About 600 of the first 1000 dollars. Hope the program is still available. Check with your nearest soil conservation office. Good Luck, Paul G. P.S. I went through 30 pages of members to find another Ioweigan!!! Nice house too.
I grew up in Iowa , Quad Cities and know where Winterset is but am a Jayhawk now. Welcome to LogHomeU. Your home looks great. I would try and contact the county extension office. Sometime they are affiliated with universities. Not sure if they would be with Iowa state or Iowa, but they would be able to advise you on native plants and what type of soil as well as care for them. They may also have some for sale. In Kansas I bought a songbird plantings package from the extension office and they had other types of plantings also. I hope this will help.
