It's a BIG mistake to put rocks down in landscaping. The desert look belongs in Arizona, not FL. Rocks will increase your ambient temperatures (do we need that?) and I guarantee you, it will not keep weeds out. Weeding is much more difficult around rocks (if you want to remove weed roots). If anything, use pine bark instead. It's a good idea to put an under layer of weed cloth, but you really don't need to remove the pine straw. It will disintegrate eventually. Just put the weed cloth over it, then the pine bark. Lots cheaper solution and environmentally sound. And consult with a master gardener about landscaping with FL friendly plants. You can do a Zoom consultation.
