Chinampas is not truly floating. But you can absolutely have a true floating garden, as long as the water is fertile and has enough oxygen in it. Plant roots can survive in water or in water-logged conditions, dissolved oxygen is often the limiting factor.

You can have a layer of soil in your floating garden too. You can mix in amendments that will make your soil very light and fluffy. A bunch of empty bottles/jars make a pretty good floating raft that can handle some weight. May not be the best if you have concerns about microplastics in your food, but that is what they've been using here in the Mekong Delta.
