need help fix brown spot and other problem
My lawn was replaced as new in 03/2013. I dont remember what kind of grass (which i ordered from homedepot). Someone can tell me what is of grass from picture. I will upload other close up photo. In May, i spread mix of fertilizer and week killer. Until June, i found many brown spots.
Other problem: Until July, i found a different kind of grass growing taller than my new grass. From the picture, you can see brighter green color which is a different kind of grass growing faster than my new grass. I dont know if these are old grass. Should i kill them or just leave?
I will upload a detail picture later today.
