•For your garden soil, 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, you should mix 10–50% rice hulls into the potting soil.
•Rice hulls can be used as a mulch for your bedding, similar to how you would 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.
