How to best encourage native grasses to establish?
We moved into a rental home with St Augustine surrounding the home in the back, and the rest of the yard overrun with invasive weeds (thick, brambly, horrible weeds).
Took us three months to pull out the weeds, then we put down native grass seed (buffalo grass, curly mesquite, and blue gramma). The grass is slowly establishing, and growing with it are a bunch of sunflowers and some hairy vetch-which we're leaving alone to help naturally build up the soil & beneficial insect population. I'm wondering if there is something (other than compost) than I can use on the yard to help encourage grass growth. I know traditional fertilizers will kill the native grass, and our compost bin can only make enough to cover a small part of the yard.
We're hosting a reception in our yard in September, and it would be great if we could get the grass to fill in by then.
