Best for everything growing.

I purchased the worm castings for my outdoor vegetable garden. Works wonders. My wife sprinkled a bit in n indoor vine and two weeks later the vine produced the coolest little white flowers. It had never bloomed.
Special care, gets special results. Jim

Love This Stuff!

I tried worm castings for the first time this year and was so pleased that it was organic and I didn't have to worry about burning my plants by over-fertilizing! It's really helped my transplants and I will definitely be ordering more to use throughout the growing season!

Safe & Organic Soil Builder

Benefits of Using Simple Grow Worm Castings

Provide plants with the nutrients they need to grow strong and healthy with 100% earthworm castings.

According to the USDA Natural Resources Conservation Service, worms digest the plant material they ingest and concentrate the nutrients in their castings. Their castings are extremely rich in phosphorus, nitrogen, potassium, and magnesium.

They also contain live organisms, like actinomycetes, fungi, pseudomonads, beneficial bacteria, yeasts, plant growth regulators, molds, and trace elements. All these elements work together to create a favorable environment for plants and stimulate their growth.

Our worm casting Soil Builder is safe to use in any quantity. Your children or pets can safely play in the garden, and you can safely store it your garage, basement, or garden shed, without worrying about unpleasant smells or pest invasions.

You will find numerous ads for soil enhancers based on worm castings for sale. Many of them refer to soil with impurities, chemicals, or other ingredients not suitable for growing your precious plants. We sell 100% organic, pure earthworm castings, perfect for organic farming and gardening, and for use in decorative areas, like gardens, lawns, and greenhouses as well.

Our prices are already unbeatable, but due to the purity of our Simple Grow Soil Builder, a small quantity is enough to enhance the soil and let you obtain amazing results. To convince yourself, you can begin by ordering our worm castings 12 lb bag. Spread it on the soil in your garden and compare the plants growing in that corner with the rest of your garden. The results will speak for themselves.
