I have been spending a lot of time in the yard trying to gauge what my problems are with it. Basically, I have a lot of dead, dry grass matting down the healthy grass in my yard, killing it off and creating a lot of brown patches. I thought to help break this layer up I would aerate this weekend, but the more I research on this site, the more I think a power rake may be the better option. to give you an idea, in 2 minutes of light raking with a leaf rake I pulled up a wheelbarrow worth of dead grass. My yard is about an acre and a half, so no matter what I do it will be a day's worth of work. Was I right that aeration would break this up and benefor the grass or should I go with the rake that will pull up this dead stuff but may cause more harm to the turf? Any help is appreciated. I hope to get this done this weekend!
