1. Do I need to aerate the lawn or can I just spread topdressing?
2. Should I mow first? How high should the lawn be?
3. How thick is recommended?
4. I heard that you can have a problem with weeds after topdressing. Should I put down some pre Emergent after topdressing?

Thanks

1. Definitely aerate. I've seen dramatic results between aeration and no aeration with topdressing.

2. Scalp the turf as low as possible, preferably 1" or less.

3. I generally topdress with compost between 1/4" and 1/2", depending on condition of existing turf. No more than 1/2" for sure.

4. I've never had a problem with weeds, but I always do topdressings in the fall. I also inject seed into the compost while I do the topdressing.
