Spread 1″ to 3″ on loosened Super Doo and spade in. After rains, scratch into the soil again. For mulching add 3″ and till into soil. For potting, use 2/3 soil to 1/3 Super Doo.

How to Use Super Doo

Mulch: Spread 3 inches of Super Doo around plants, trees, shrubs to retain moisture, suppress weeds, and keep your soil cool during summer months. Adding a thick layer of Super Doo in the fall helps protect your plants during the winter.

Soil Amendment/Fertilizer: Super Doo contains the vitamins your plants need to thrive. Loosen soil around annuals/perennials, add 1-2 inches of Super Doo, and till into the soil with a small spade or with your hands. For best results: after the first rainfall, till the soil again, being sure to mix Super Doo into the earth around your plants. Rather than rototilling your vegetable garden every year, use Super Doo to supplement lost nutrients and augment the growing season.

Potting Soil: Keep your indoor and outdoor potted plants healthy and happy all year round. Super Doo provides nutrients to your plants and allows the soil to drain well. For best results, use 2/3 soil to 1/3 Super Doo.
