Q.compost addition to lawn
Debating about use of Soilbuilder or mushroom compost to mix in with existing soil. Want to seed again after I tilled and removed an old lawn. But worried about two things: Salinity content of the mushroom compost mentioned here and the nitrogen content of either option. I plan on using centipede grass seed to start my lawn and understand its sensitive to high nitrogen fertilizers?
I would start with a soil test. This will help you determine the best amendments if any needed to get your soil ready for the new grass.
