•For the garden–spread about a two" layer across the surface when you fertilize in the spring, and mix it into the top 6–12" of soil.
•For potted plants–mix 10–50% rice hulls into your potting soil.
•You can also use rice hulls as a mulch, just like you’d use straw.
•Rice hulls are extremely lightweight, so they’re especially ideal for rooftop gardening or other gardens that require an amendment to make your soil lighter.
