Is it possible, with good result, to save potting soil, add fertilizer to overwinter and reuse the next Spring. I would incorporate some mulch materials to like leaves, eggshells and coffee grounds,.

    I have reuse potting soil. Add the organics but not the fertilizer.

    I save my potting soil and in the spring I sift through it with my hands and remove any old roots. I don't do anything after my plants die, I just leave it in the pots. When I am ready to reuse I add some fresh soil and mix it well and plant. I then place a little fresh soil around the top of plant.

      Thanks, Millie...wasn’t sure if the soil would get tired and hate to keep paying for something that is t really needed!

    I have used the same potting soil in containers for 20 years or more. Nothing added until after replanted with flowers. Just a spray of miracle grow. They are gorgeous every year.

      Thank you...I love Miracle Grow too but thought maybe the soil would need refreshing...my plants have been blooming fine but was afraid one year I’d be disappointed. Your track record is encouraging.

    Karen, Your soil will do great with the additions you are talking about. I never throw my soil out either

      Thanks.......I wonder sometimes if I’m being too scrupulous in trying to conserve the soil but I’d rather try to invigorate what I have instead of buying more each year.

    I wouldn't. Soil carries bacteria that may multiply....I would start fresh.

    I always reuse mine too, or empty it into my raised bed and have never had a problem with disease :)

    I have reused potting soil with great success and didn't do much, except clean out old roots.
