yoderjack,
That imperialistic BOB blue coated clover....... IS that durana with a smurfberry paint job?
I've had good eperiences using medium red clover as a nurse crop with white perennials. IF You mow a few times a year, the red just about never makes year 3. IF you mow to make it retty, or calm down competitve weeds or grains, you definitely need to frost seed. Easy to do, but just about necesary to maintain a clover plot for numerous years.
As far as the BOB goes, I'm operating at scale and don't use BOB seed any more because of the huge cost it would be. All seed needs to have a seed tag that shows what is in the bag, even BOB seed. That is how you would tell what variety it is.
I've had poor success using Medium Red with perennial clover like Durana. Medium Red is a short-lived perennial. My results when mixing it with Durana is that I get patches of Medium red in the Durana. As the Medium Red dies out, it is filled by summer weeds rather than the durana filling it in. I don't mix them any more.
I NEVER frost seed to establish perennial clover. It makes much more sense to fall plant and use a WR nurse crop. Much of the clover will germinate in the fall but not grow much. This gives it a much bigger jump on competition than frost seeding. I do use frost seeding to overseed an existing clover plot if it has bare patches, but never to establish perennial clover.
As for mowing, I only mow to release clover in the spring following planting. It is keeping the WR alive, but allowing light in for the clover to establish. Once established, I become very weed tolerant. My clover plots start out very clean with this practice, but once established, I become very weed tolerant. In a 2 year old plot you would not even know there was clover in it during the summer looking from a distance. Many of those weeds are good deer food and don't bother deer use at all. They shade the clover from the hot summer sun as well. Come fall, when the cool evening and more reliable rain favor the clover, I mow once right before the season. What looked like a weed field becomes almost pure clover as the clover bounces back. I do no other maintenance or herbicides. Each year, the proportion of weeds increases a bit and after 7 to 10 years the field needs rotated. I do no other maintenance.
I've I'm too lazy to rotate when I should, I can get a few more years out of a field by bushogging it flat to suppress the clover or by hitting it with 1 qt/ac gly to top kill it and then drilling GHR and WR into it.
Thanks,
Jack
