Q.Making “light” Dirt Heavier
For the sake of water conservation, we have let our lawn die. As it is dying out, and drying out. I’m finding the dirt underneath is very soft and light. Enough so as to blow in the wind. Everyone says the only solution is mulch or woodchips over it. I would like to find something I can mix in with the top soil to make it “heavier”. I am thinking maybe sand. Regular construction sand. But I can’t find any information. Do you have a recommendation for something that might serve the purpose? PS:This service you offer is amazing! I thank you!

You can always mix in bagged garden soil or topsoil. The sand would be OK if you get builder's sand and not fine sand. But it might filter down and leave the light soil to still blow away. If you think you might plant grass again eventually you could topdress with manure. Here are some ideas:
