Do not use rocks--they don't stop weeds and make weeding harder. Lay down weed blocking cloth (available at garden stores), set in your plants and use pine bark or straw around them. Nothing really stops weeds, but you can delay their appearance. Absolutely do not use Roundup (glyphosate). They are terrible for bees and the environment in general (and for yourself). We must all do our share to not harm the environment. If you prefer to spray, get some 30% home & garden vinegar, which you can buy online or order from Home Depot and pick up in a few days. An argument against rocks in the landscape: you are in Florida. We have green year-round. Why adopt the desert look? Rocks increase ambient temperatures and don't really block weeds.
