What are you using as mulch?
We buy hay by the big round bale from a local farmer. Since we mulch over 5 or 6 layers of newspapers and cardboard boxes (from cereal, pasta, etc) we don’t worry if we’re spreading weed seeds in the garden. They just get covered over again next year. We also use raked leaves and grass clippings from our yard. We usually try to sweep the leaves off the neighbors yards too. On the beds that are in the ‘yard’ and part of the ‘landscaping’ we use regular old pinestraw over cardboard boxes.
