Pike, I've never tried that product, but I've planted similar mixes. Results may be different for you, but it seems the brassicas will crowd the clover to the point it never has a chance to grow. I planted at the end of July and that may have caused the problem. It might be best to grow brassicas alone too, just my opinion. I read a couple years ago that a veryreputable seed company(Barenbrug) produces that mix(Ultra Forage)and they also produce a lot of Ag seeds, so they might have it figured out. But if you want to put together a mix and possibly save a few bucks we could do that too. I'm a tight wad except when it comes to minerals[8D] What ever you decide let us know how it goes and Good Luck!!!
