Dried rabbit manure. Very little hay, if any in these bags of bunny marbles. Each bag weighs 20-25 pounds. Call or text for more information. With spring just around the corner, planting season arrives. Rabbit manure builds soil structure by adding humus and attracting earthworms. It is a cool manure that doesn’t need to be aged before adding to the garden. Excellent choice for mulching garden beds and shrubs in spring & fall. Just mix some “bunny marbles” into your soil and watch them work their magic!
