My front yard is sloped and full of dandelion weeds to the point that almost three-fourths of the yard is gone. What steps should I take in order to get my grass back. Since Zoysia grass seed is hard to find and expensive, is there a different grass seed I could use or stick with Zoysia. I live in Columbia, South Carolina, where the summers are really hot.

I can provide pictures of my lawn if need be.

Thanks for any help you can offer me.
