Grass
 

I had a lawn full of weeds last summer, I've been afraid to put down regular fertilizer because of our dog. Before we had a dog, my grass looked great, but can't get rid of the dog now.
My question is...
1. since it's a mild winter up here in Mass. is there steps I can take to start my way to a nice summer grass now??
2. Also, I have a lot of valleys or low spots in my grass, can I just loam and seed on top of the existing grass to even the grass.??
3. Also, have spots where water collects, and thus have moss, should I just lime the heck out of those areas???
Thanks

May want to look this site over for some good advice.

Moss can be caused from to much fertilizer, and trees need thining.

You can just seed over it ( its called over/inter seeding) but depending on the size of the area I would rip it up and reseed it if it's small. No need to do things now unless you put an application of organic fertilizer on it.
