Thank you for visiting  BLACK DIAMOND VERMICOMPOST.  We are located just a few miles east of Paso Robles in vineyard country…the newest & hottest wine destination in the Central Coastal region of California.

The production of high quality, fresh vermicompost is our primary focus. Black Diamond Vermicompost is available for purchase right here where the worms live. Call before you come please; we do not have regular business hours. Delivery service for bulk orders is available; call for a price. There are local retail outlets as well – they are listed on the vermicompost page.

We do sell composting worms too. See the “Links” page for information on setting up worm bins at home, as well as links to some of our favorite local spots.

A popular service we offer is Compost Tea Application. This can be foliar spray, deep root application for vines, trees and shrubs, or soil drench. The popular deep root application uses specialized equipment to inject compost tea into the root zone. This process creates soil microbe resevoirs, air pathways for roots to extend and adds organic matter to the rhizosphere to feed the plant or tree. See Help trees through drought for a DIY method.

For questions or to leave comments, see our BLOG TOPICS at the left.

You will find some fascinating information about worms and scientific papers at Studies & Findings; you can order fresh aerated vermicompost tea or extract too.

Many organizations have invited us to speak. There are several educational and entertaining options! Black Diamond Presentations – print out for your speaker coordinator!

Following the latest scientific studies is high on our list…we are continually conducting our own trials as well. You too, will learn the importance of adding biologically active vermicompost to your soil. It will change the soil’s structure, plays an important role in a plant’s defense against pests and disease and increases the soil water holding capabilities. These are just a few of the qualities you will observe when Black Diamond VermiCompost is added to your soil or planting medium. Please call us at 805-674-0194. We invite you to see the vermicomposting facility and learn how our vermicompost is produced and why it continually exceeds our customer’s expectations.
