ok, this is probably an easy one for you but i've never heard of it. i planted some seeds and covered with soil. two small areas. one area came up sparse and a couple weeks later some of it appeared to die. the second area is about 3-4' away and came up incredibly thick (kind of freaky looking). same seeds. same soil on top. the blades in the first area that look dead have this brown spot about half way up the blade. green on bottom, dead in middle, green on top. wilted over. what is this?? any cure? i'm thinkin' this is a one way ticket to starting over. thanks for any replys.
