One tip for you three, you should let the goat's into the garden, once you've harvested everything and are growing anymore for the year. The goat's will eat the overvgrown plants, as well as thebweeds and leave their poop behind to fertilize the soil. Also, when goat's eat they have a method of chewing that destroys the weed seeds so they don't come back. Goat's are way better than any weed killer out there.
