Have a few areas being cleared to turn into plots and I assume I will see a lot of seed bank competition come spring. That said whats the best thing to start with in these spots to allow easy control of competition with herbicide or mowing?

If I plant clover whats the best way to knock back the competition come spring green up? Would Poast Plus kill tree resprouts?

I am also considering just planting grain rye and wheat as a first crop and mow it down and spray with roundup in the summer. Then work to establish clover plots next fall.
