I disced and planted a recently widened trail this spring. I did not get a soil sample but will be getting one in July. I have laid lime and know it likely needs more. I planted clover and buckwheat and it is doing OK for the most part. I am getting some ferns (mostly around the edges) which used to rule this trail. I plan on a July spraying with Poast and 24db to handle grasses and weeds and then I plan to spread more clover and WR (as a cover crop) in August. My question is, will the 24db take care of the ferns or will I need something stronger?
