Sounds like a good plot. Your question is a tough one. - I assume you plan to let the plot winter over - and be mostly clover for the next couple years.

Assuming this is so - mowing is definitely in the future anyhow, BUT now' s not the time, Given that its mid summer - I' d let the grass act as a nurse crop for the clover (along with the greens). Mowing will hurt - but not kill off the soybeans, rape, and turnips - it will slow down grasses, but not kill them either, especially a " topper" type mowing - it invigorates grasses. I' d let them all grow.

I think you' ll find that if you have good Nitrogen levels, the Rape and Turnips will " take over" in a couple weeks.

PS - Just for the heck of it - mow a 10x10 ft or larger section - its the BEST Way to learn - don' t just take advice, people aren' t always right - and every plot/property is different.

Good luck,

Take some pictures (before and afters are great - we all learn)

- let us know how you make out
