Weeds and Compost
Weeds also make a great addition to your compost pile. Some weeds have deep roots that go way down into the earth. That means they can pull up minerals that cannot be reached by many vegetable plants. When you throw the weeds into your compost pile, the nutrients end up in the compost and then become available to your plants when you use the finished compost.
