great for bulbs

My spring bulbs are blooming better than ever. Only difference I can figure out is the worm castings I sprinkled on them last fall. I wintered my roses last fall and added worm castings. They died back to the ground but are vigorously sending up new shoots this spring. My soil testing shows no extra fertilizer needed but the worm castings made the difference. I will keep adding. them to my garden every year.

Love these worm casings

This is the best stuff! We can apply it directly on the plants without burning them up, and the plants love it! This is the second ton of worm casings for us and so glad we found Simple Grow! And we found out they're local!

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.
