This is my third year in attempting to get a nice patch of wild flowers going and each has met with miserable failure.
First year I simply mowed the grass to the lowest level, sowed the seeds and raked them in. Very few of the seeds took and they were largely overrun by the other grass and vegetation.
Next year I tried a minimal tilling. Breaking the soil roughly and followed the same process, with the same results.
Last year I completely tilled a spot, breaking up the soil nicely and tilling under all the existing vegetation. Then sowed the seeds...and got the same results.
I have even tried growing some in potting soil and transplanting them. I got some decent flowers the first year, but no reseeding the next year.
I was under the impression, mistakenly apparently, that wild prairy flowers were a hardy bunch that grew like weeds...but I can't get them to grow. I want to get a half acre to acre plot going so I can't be singularly replanting the flowers every year. Anyone have any suggestions on a better, more successful approach to this?
FWIW I did the same thing with clover and had decent success. The Dutch clover is all over the place and the crimson clover grew well for a couple years. Yellow clover didn't do that well though.
