I use Hi-Yield Weed & Feed. This product combines a granular weed killer and fertilizer. It kills weeds while providing enough nutrients for Zoysia grass. The fertilizer has enough nitrogen and potassium for Zoysia lawn. I just started gardening this spring, and I learned about this fertilizer from an
explained video on one gardener's blog. I don't have much experience, so I do a lot of reading and watching on this topics. The weeds have decreased, the grass is growing great, I think this is a really good remedy.
