    Another post on weeds…

    Torilis arvensis, Spreading Hedgeparsley Arrrrrgh!

    Judith Larner in ‘Gardening with a Wild Heart’ says “Somewhere in all this activity (of discovering CA native gardening), the gardener notices that most of the work involved is weeding. The story of gardening in California, and indeed the whole world, is the story of weeds.”

     

    Do not let weeds go to seed….   One year of seeds brings seven years of weeds!

     

    • Much of the pleasure of gardening depends on having the right tool for the job.
    • Cut the weeds off at the soil surface thereby eliminating the weed’s ability to feed its roots.
    • Cut weeds off with this tool you can simply leave them on the soil surface to dry and decompose over the course of a week or two
    • Cultivate just deeply enough to cut the weeds off below the soil surface. Do not over cultivate.
    • Less soil is disturbed, which brings fewer new weeds to the surface

    The indignity of it!-
    With everything blooming above me,
    Lilies, pale-pink cyclamen, roses,
    Whole fields lovely and inviolate,-
    Me down in the fetor of weeds,
    Crawling on all fours,
    Alive, in a slippery grave.”
    –   Theodore Roethke, Weed Puller, 1948

     

    Every way I know to control weeds

    Hand pull
    This is the actual pulling of weeds by hand.  Simple.  Primitive.  Zen.

    Sweeping
    In the Southern US, garden paths are sometimes swept clean of leaves and loose dirt. This keeps weeds from sprouting. I have tried this and it works well.

    Cultivating
    Scratching the surface to kill weeds with tools, hoes cut off roots at surface. Hoe weeds before they go to seed! This tip was given me at a garden workshop at Roger’s Gardens.

    Hoeing
    Clear an area, water it and let the weeds sprout. Hoe them away and repeat. Takes a long time, if you have it.

    Organic Mulch
    Lay down a thick layer of mulch without weed seeds in it such as straw. Mulch can be put around plants a few inches away from the stems

    Plastic mulch
    Lay down plastic and plant in cut out holes. Some problems are that plastic breaks down quickly, looks messy and blocks water.  I have seen a lot of ugly plastic.

    Plant a cover crop
    Plant a cover crop that outgrows the weeds. Unless it’s a native seed, I would never do this for fear of runaway weeds in unintended areas. Sounds expensive??

    Weed whacking
    Weed string trimmers do the job along driveways, fence lines and edges. We use it to trim dry brush and grass low enough for fire safety. Do this before the weeds go to seed. (See first quote, above)

    Flame weeding
    Uses a propane torch to kill the weeds.  We have a flamer, but I have never used it, Has anyone had a good experience with this?  My mother would pour boiling water over weeds in concrete cracks.

    Spraying with glysophate*
    Broad-spectrum systemic herbicide
    Use carefully in certain cases. I use this,…carefully, on our mile of paths.

    Drip irrigation
    For areas with long dry seasons bury your drip tape and irrigate only where needed.  Death by drought.

    Use animals
    Deer are decorative and weed out non-natives like roses.
    Sheep will eat everything they can reach.
    Goats will eat everything they can reach including Poison oak.

    Make a salad                      (Thanks to Brent of  Breathing Treatment )
    Purslane,
    Dandelions,
    Lamb’s quarters, all edible and (probably) nice with a homemade vinaigrette.

    If you have a weed that you don’t see here would you make a comment about it and I will add it to this gallery?  Thanks!  Also share if any of these methods work for you.  Everyone has a strategy, even if it is to look the other way. I once built a low fence around my veggie garden, so I wouldn’t have to see the weeds from my kitchen window.  Worked!

    Weed identification Sources

    Oregon State University
    North Willamette Research & Extension Center Main Weed page
    Oregon SU Weed Identification Guide Lots of photos, easy to ID weeds.

    University of California-Davis Main Integrated Pest Management page
    UC Davis Identification: Weed Photo Gallery includes many, but not all, weed species commonly found in California farms and landscapes.
    UC Davis  Weed identification tool—a technical key to identifying weeds, from the UC Weed Research and Information Center.

     

    *We also use glysophate responsibly on poison oak. Some don’t agree with this, but we have 7 acres to keep safe for small people and dogs…just can’t have it and the systemic action means it gets killed through the roots so we know it’s gone for good.
