I need some advice on what might be the best cover crop for the garden in Central Texas?? I usually plant rye for fall/winter and after the heat starts this time of year and shred the rye, I would like to plant a cover for the unused portion. To date, I have tried Buckwheat - works well but when it gets really hot (July, August) it will begin to flower and seed real quick and almost had a problem last year. Cowpeas do well in the heat and could possibly be the solution. I am however concerned about not rotating and beginning to have disease/pest problems for future legumes. Any suggestions?? Thanks in advance.
