Correct topsoil?

Post by Camman595 »

I am in the midst of a front/side yard reno. The side of the house needs quite a bit of topsoil to get the grading right. In some places, I need to add 8-10" of topsoil. The places around me sell topsoil and a topsoil/compost 50/50 blend.

Would using the blend be beneficial for lawn use? Would the compost decompose and then 50% of my soil be "lost" over the years? I am going to put a lot of effort into this reno, I don't want to be making corrections later on due to choosing the wrong product now. Any suggestions are welcome.

The compost will decompose over time and the final grade will drop. With 50% compost, you will lose ~50%. If you can custom blend the soil, then 5-10% compost is what I would ask for. If you can't, then you want to try and match soil composition (i.e. sand/silt/clay percentages) to the current soil.
