Yes, I can see that now that you mentioned the San Mateo golf course.
I am planning to use a product called "Profile Clay Soil Conditioner," by
a company called Schultz.
It claims to be "ceramic granules made from 100% natural minerals," and
lists as Ingredients "100% Arcillite."
Sand is a known quantity to me, but I was thinking of trying something more
''modern.'' if it is acceptable.
I worked sand in to my garden plot some years ago, and, of course, my
compost every year, so it is really wonderful--but the lawn is another matter.
If I could break it up I could make pottery from the clay, it is so bad.
The onliest thing thriving is weeds, weeds, weeds, and my bad back
precludes much digging and spearing.
I live two blocks from the Potomac River and don't want anything going
into the river from me--but I would like more grass in my lawn, and less
crabgreass, chickweed, poke weed, plantain, clover, and whatever.
My neighbor and I are hiring the plug aerator and a guy to do the work on
our lawns and we are splitting the costs.
Following other advice on this group, I plant to put some of my composted
material, and indeed some of my wonderful garden soil on part of the lawn to
reintroduce lots of good micros.
I expect this to be a several year project.
This land was once an orchard owned by Geo Washington. I sure do pity the
poor suffering souls who had to grow anything for him in this stuff.
