Q.Is it Shasta Daisies or is it grass?
I planted Shasta Daisy seeds in April (in southern California). I followed the directions and eight weeks later it looks like a thick carpet of grass and nothing else. What do Shasta leaves look like? The seed company showed me a picture that looked similar to the leaves I have, but I am still worried that the previous lawn has come back to life even after we killed it off and roto-tilled the area and waited a long time before planting. Should I give up and start all over?
Without a photograph, I can't really make a judgement call on what it is that you have. Here are some links that will show you what the foliage of shasta daisies looks like so you can make a determination:
