The Frame It All Worm Box is an essential component to every raised garden, to add to the quality of the soil and in doing so provide for sturdier and healthier veggies, fruits and flowers. Locate it in the soil in the deepest of your raised garden beds. The easy to assemble, affordably-priced, Worm Box - Limited tools required, has multiple entrances in every surface to encourage worms to take up residence. Add chopped up leaves, grass clippings, torn up wet newspaper and mealtime scraps to create your own compost. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. Their digestive system concentrates the organic and mineral constituents in the food they eat, so their casts are richer in available nutrients than the soil around them. Nitrogen in the casts is readily available to plants. Worm bodies decompose rapidly, further contributing to the nitrogen content of soil. Worms often leave their nutrient-rich casts in their tunnels, providing a favorable environment for plant root growth. The tunnels also allow roots to penetrate deeper into the soil, where they can reach extra moisture and nutrients. Earthworm tunneling can help incorporate nutrients and fertilizer into the soil. Soils with earthworms drain up to 10 times faster than soils without earthworms. Their tunnels also act, under the influence of rain, irrigation and gravity, as passageways for nutrients and other material. Color: BLACK. Material: Plastic.
