Soil Boost FAQs

What is vermicompost?

Vermicompost is essentially worm waste. In typical vermicompost bins, worms feast on food waste and turn it into “casts” or worm manure. The benefit? Passing through the worm’s gut helps deactivate any harmful bacteria for your garden.

What are the benefits of vermicompost?

Vermicomposting helps keep food waste out of landfills. In landfills, food breaks down without air and produces methane gas, which is very harmful to our environment. By using worms to break down food waste in a compost bin with air, vermicomposting reduces landfill waste and cuts down on harmful gas emissions.

How do I use it with other Sunday products?

Let Soil Boost to completely dry before applying other products. Apply Soil Boost a few hours to days before using other Sunday products like liquid garden or lawn fertilizers. This allows for better nutrient absorption of both products!

For best results, use Soil Boost in combination with Sunday fertilizer, weed control and garden soil. This will help you fertilize plants properly, reduce weeds, and introduce nutrients back to your soil.

​​How and where do I store products?
