    Looking to buy Pumice (Central Coast, CA)

    I'm looking to buy some pumice locally for relatively cheap. I live between San Luis Obispo and Santa Barbra, California, and have had no luck at local nurseries, stores (like Home Depot, Lowes, and Farm Supply), or bulk garden/stone suppliers. The cheapest pumice I have found is "E.B.Stone...

    Please advise on pumice

    I am in the market for a big bag (1000L) of pumice but I dont know what type is best I also dont know if azalea roots can penetrate pumice like Kanuma, in which case I could pick the larger grain.

    Where do you find your soil?

At first I bought those expensive “bonsai soil” packs, but the more trees I get or make the more I look for cheaper options. I‘ve...

    Perlite as Pumice in a bonsai mix

    As it is almost impossible to buy pumice in Brazil, my question is: Can Pumice be switched by Perlite in a bonsai mix? Regardless of color and lightness of the Perlite, of course.

    Collected Mugo Pines. Help!

    So I just got two mugo pines from free Craigslist (like 5 mins ago). I know it’s the wrong time of year to be doing anything in the way of collecting/planting/potting, but the guy wanted them gone ASAP. It also happens to be 100 degrees in Michigan today (great lol). My question is, to keep...

    Preparing for repotting season

    I finally found some time to head to the gravel yard a couple hours away and get a have a yard of lava cinders and a half of yard of pumice. I combine this with diatomaceous earth (Napa oil dry) and some potting soil/ compost/bark mulch and it works good for 100"+ of rain a year. I still have...
