        First the Drainage Myth problem…

        drainage myth

        Soil in a plant pot or container has a saturation zone at the bottom where the water is held in the soil matrix above a transition layer.  If you add gravel then the saturation zone moves up and you have less growing room for plant roots to expand.  You’ve just put your plant in a smaller pot.

        Next Soil pH Testing – Here’s a link with details on testing garden soil, and there’s a video showing soil collection.  There is also a Soil Test Interpretation Guide If you want to collect soil samples for testing you can get them to me before April 1 and I will run the assays at OSU Extension – $2 per test or 3 tests for $6 for Garden Club Members.

        The best place for detailed soil analysis is here:  https://www.simplysoiltesting.com/ They deal well with garden samples as opposed to agricultural stuff.

        Next seeds from the yellow bins:

        Golden Clematis (Clematis tangutica)
        https://landscapeplants.oregonstate.edu/plants/clematis-tangutica

        Coyote Brush (or bush) (Baccharis pilularis)  https://landscapeplants.oregonstate.edu/plants/baccharis-pilularis

        Money plant (or Honesty or silver dollar plant) (Lunaria biennis)
        https://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=278072

        This turns out to be moderately invasive in the PNW as a forest understory plant.  If you want to grow it for dried arrangements, cut the drying stems before they become brittle and collect the seeds in a paper bag.  You can use the dried stems for arranging and keep the seeds out of general circulation.

          Great info….thx. I didn’t know about the gravel-in-pots thing.
