Compost Seeds

I have a compost bin. Actually, I have four of them. Because I’m all about being eco-friendly, I use compost to enrich the soil. About two years ago, I read an article that stated: “Most home compost bins do not get hot enough to kill weed seeds.”

Well, that explained a LOT! For a number of years, I was inadvertently putting weed seeds back into my garden all the time. I now understood why I never seemed to get a handle on the weeds—and why they started showing up in places they’d never been before. I had been blaming the birds—but all this time, it was my ignorance about weed-seed-free composting!

These days, I only compost leaves, coffee grounds, and vegetable and fruit scraps. Except now I’ve discovered a new, painful truth. Watermelon rinds attract bees. Bees will attack if disturbed while they are enjoying the watermelon rinds.

I learn something new every day … most often the hard way.

  • I was just thinking about this very thing today. My small, neglected vegetable bed is absolutely chock full of weeds and I realized that they had probably come from the “compost” I had used from our compost bin in the spring. And now, thanks to this article, I know now to rectify the problem 🙂
