Chufa has been one tough crop for me to pull off...it continues to be an ongoing experiment on my place. The very first time I tried it turkeys scratched it all up. Other times have been met with very little success so I continue to try it in different areas/soil types, planting dates, and depths.
As far as mixing it with others I really can't weigh on that...still trying to get it to grow well just by itself. :|
