I found great composite wood look heavy duty snap together raised beds at sam's club very reasonable, but now have to fill them with soil. Square foot gardening book recommends 1/3 coarse vermiculite, 1/3 peat moss and 1/3 compost - I'm worried this will dry out very quickly in our Florida sun and am tempted to use at least a good percentage of Miracle grow garden soil Does anyone have experience with quot;Mel's mixquot; soil and can you tell me if it dries out rapidly? Our prime gardening season (fall) is coming up and I plan to be ready with my new raised beds! The beds will be in mostly sun and placed directly on the ground.
Home Depot, Lowe's and your local nursery should sell bags of Vermiculite.
I think that most garden stores sell it already mixed into potting soil, so that is the way most people buy it.
Here in So cal all our Lowes and local plant nurseries sell it. Try calling them ahead before making a trip all the way out to you local nursery. That way you wont waste a trip driving out there only to be disappointed.
