The asbestos concerns stem from one single deposit found in Montana. That mine was closed in 1990, so there are no concerns when it comes to the vermiculite you use today. We want to clarify that the vermiculite sold in stores today is safe to use in your garden!

Yes! Other than potatoes and carrots (we build the soil up for those), you can grow almost any vegetable in 6” of Mel’s Mix. If you have a deeper bed, we recommend filling the base of the bed with clean builders’ sand, add a layer of weed cloth or cardboard, then add your 6” of Mel’s Mix. You don’t need any more as it will be wasteful.
