Clover can do a pretty god job of choking out weeds but you have to mow it a few times to get there. I can tell you by looking at my lawn that you don't need to till to grow clover lol.
I tried it without much success. The soil here isn't that good but a trip with the tractor tiller with some lime and fertilizer and it works pretty well. I do plant mixed birdseed right from Walmart with good success every year.
Well I spent yesterday covering an acre with waste hay and manure mixture it's about 8 inches deep. So I guess we will find out in the spring if it was a good call or not, it should have about 5 months to break down, from what I am reading you should be able to trans plant from containers directly into the hay.
I put the white clover in an area that had better soil as I pushed the brush back there. The only clear areas I had to start with were log yards where the soil had been scraped down to the marl.
I've had some success seeding my trails and small plots with this method. I mix red and white clover with some oats. Put it down. Put down lime and fert. Spray existing vegitation with gly. Wait a week. Then mow the slightly dead vegetation. It creates a layer of thatch that helps hold moisture for the seeds.
The oats grow first and fast. Clover, especially white, is slow to grow the first year. Year 2 it really takes off.
Mow the plot before any weeds or grasses put out a seed head. 2 to 3 times a year depending on rain.
