    Potting mix

    Hi All,

    I have a significant number of bare-root shrubs being shipped to me this week.

    The pots are ready, but I need a large quantity of potting mix.

    There is a mulch yard local to me that grinds pine, poplar, and hardwood bark to a fine consistency, and sells it by the tractor scoop to the local growers. The yard owner tells me that the growers mix it with builders sand and sometimes perlite.

    I do have a compact tractor with a front-end-bucket, so I can haul-in the ground mulch and sand, mixing the products with the bucket, on the ground.

    Do you have any suggestions on how I should proceed, maybe on the correct sand to mulch ratio, and any other amendments I might add.

    potting mix

    gg-I hope someone else is more familiar with this type of barkmix. The hardwoods in there might make quite a difference.

    I have used fir/hemlock bark, 1/2in. minus, for years with great success. Using this uncomposted bark, I add probably 25% composted steer manure, plus a dusting of dolomite/gypsum, and that works great.

    I have not seen sand used in potting mixes here, as the weight and sogginess it adds are undesirable. The Ag Dept here cautions to never add more than 10% sand to a mix, it will decrease the drainage. Perlite works better, but is too expensive for regular potting mixes.

    I mix by laying down a layer of both materials in the rough proportion I like, dusting on the limes, then running the rototiller back and forth until it is well mixed.

    As I say, your mix of barks might work quite different than mine. Still couldn't see using sand in it, unless you needed the weight for stability of the pot/plant in wind...

    Welcome to Landspro, gardengym!

    I visited your website, and it is quite nice. I love that dark red daylily!

    Thank you for adding a link to the Landspro Forums!!!

    Regarding your question.... I think the answer depends on what it is you are trying to grow and how coarse your builder's sand is. Ours tends to be very fine, and I would think that you would want to use a more coarse grade of sand.

    I found an article that may help. It includes numerous "recipes" for potting mixes...

    Thanks Ann B.

    The link is exactly what I need.

    Seems like experimentation is called for.
