Needing to fill as well as feed. What compost/topsoil ratio?
Hi, I don't want to go overboard with the compost, but my lawn (seed was started on tilled topsoil fall of 2008) needs some filling. The builder's sub did a horrible job of evening out the lawn. There are hills and valleys. Also, we have come across large rocks that were on the lawn's surface. When we removed these, we're left with craters.
1. Should I fill the craters with straight topsoil?
2. Eventually, we need to add about 4" of material to 50% of the lawn. (We're not going to do that this season.) Should that be 50/50 compost/topsoil?
Note (in case this changes the answer to question #2): We have drainage problems. They've been slightly improved with the new grading (the basement of previous house, which was knocked down, flooded constantly). Now we have several large puddles throughout the lawn when it rains.
I had a great time searching through old posts.
