Preferred newsprint for your garden will have used nontoxic soy-based ink.
Layering yesterday’s news onto your garden is a great way to recycle newspaper in the garden while building wonderful soil. Simply take a section of the paper running at least 8-10 pages thick, and apply it to either a new or existing bed. Be sure to overlap these sections in order to help prevent any future weeds. Wet the paper to help hold it in place, and then add a 2-4 inch deep cover of quality mulch, such as Black Gold’s Garden Compost Blend or Natural & Organic Soil Builder.
