I don't have any real sandy areas that i plant on so no. However, I know some guys that have decent luck with planting Durana clover as well as Ladino clover. If you can get it established your good. it all depends on how much moisture we get and rain in Oklahoma that past 5 years or so has been very unpredictable. What you might want to do is plant buckwheat this spring and try to work on building up some organic matter in the sand and then attempt to plant your clover in the fall with some oats and wheat.
