    There is a fairly large area of my garden where it is very difficult to control weed germination year after year. Although all the perennial weeds are gone, it is a big challenge for me to remove thousands of annual weeds before they set seed. (So much water flows through this corner of the garden in the fall and winter that a cover of mulch would get washed away.)

    I think I will try solarization on at least a section and see if it helps reduce the number that germinate. I'd remove all the existing weeds first so the soil would be bare. I've read this article (and others) but wonder if any of you have had a positive experience with solarization. Soil Solarization for Gardens & Landscapes Management Guidelines--UC IPM

    The biggest obstacle this year may be the lack of sunshine - quite a contrast to 2021.
