    Call your local pool builder. It is used as the base for all vinyl liner inground pools before the liner goes in. Be sure to specify the stuff that isn’t premixed with portland cement unless you also want to dump a whole lot of calcium in your soil. Probably not a bad deal so long as you get it into the soil before adding water and don’t have too high a mix concentration. 4 cu ft bags purchased in 2013 cost me $14/bag.

    Green Island Distributors, Inc. in Riverhead, NY (east end of Long Island) are selling 4 cu ft bags of vermiculite for $22 / bag. I bought four bags yesterday.

    On the Western Slope of CO, it’s impossible to find large bags of vermiculite. Yes, Murdochs and Home Depot have them, but the bags are small. I found larger bags (4 cu ft) here:
    I ordered 2 bags. Be prepared… the shipping was almost as much as the cost of one bag, but that’s still cheaper than the same amount at any local retailer.

    In Western NY, you can buy coarse vermiculite at BFG Garden Supply in Lancaster, NY. (1500 Commerce Pkway) $32.70 for 4 cubic foot.

    Home Depot now carries 2 cu ft bags of horticultural vermiculite (medium grade). Check out the on-line website. My local Home Depot stores now have it in stock. If your local Home Depot store does not have it on hand, I think you can order it through the on-line store and have it shipped for free to your local Home Depot store.

    Course is better, regular is fine.

    I just contacted (1/19/11) Fifth Season Gardening in Greensboro, NC and they quoted me as follows: “4 cu ft. bags for $17.95, 20 Qt. bags for $8.95, and 8 Qt. bags for $4.95. We also carry coarse vermiculite in 4 cu ft. bags for $24.95”.

    My question is this: Do I buy coarse or regular?

  9. Emily says:

    And even with shipping the price is good compared to locally. Seems the price on vermiculite is going up and up.

  10. Sam says:

    You can get 4 ft. cu. bags of vermiculite for $22 online from greenhousemegastore.com
    and they will ship anywhere in the US!

    I’ve never seen pumice, I’ll have to check it out. The vermiculite reminds me of puffed rice, so that’s the texture you want to aim for.

  12. Will Glennon says:

    Vermiculite is getting way too expensive if you have a large garden. One alternative that I think might be better is pumice. It is light absorbs water and drains well and is a lot less expensive.

    Just called Farmer-D organics in Atlanta Georgia and they seem to have the stuff. About $20 for a 4 cu foot bag.
