What are the best rocks for a rock garden in Florida Sandy dirt

Have you tried to speak to your local nursery about the best rocks to use? I know that sounds crazy but they may be able to give you some tips about which may be the best and also give you some tips on how to lay it out so you don't get overwhelmed on the project. Also try some ground cover with the rock garden and the nursery people may be able to give you some tips on that along with the soil. Where I lived in Maryland we had sandy soil too and had some decent luck with phlox as a ground cover. I wish you the best of luck with your rock garden!

Call People Junction. They will ha've everything you need. They are in Sanford FL

Correction: pepple junction

Used to be back in the 60s they use old coral rock..... https://carrollsbuildingmaterials.com/landscape-products/natural-stone-boulders/coral-rock-keystone/coral-rock-marine-limestone/

If you get homesick for the mountains, use river rock. Since you are putting in rocks, you can use buckets of salt water to kill the weeds, too. You can grow almost anything in containers. ☺️

Oh, I thought maybe it was pebble junction. lol

Leave the plants in their pots and not directly planted in the soil.
