We live in San Diego, CA, and our lawn is yellowish depsite a lot of water. Recently, we added a load of Scott's TurfBuilder with an empahsis on the "green" portion.
Nothing much seems to be happening. We suspect our soil may not be that good.
Would it be a good idea to dump a load of gypsum directly onto the lawn to break up the clay beneath?
We appreciate all ideas on the least invasive way to improve the soil below our lawn? We have about 5000 sqft of lawn.
