Do You Sell “Living Soil” Products?

“Is Sunshine Advanced Mix #4 considered a living soil? If not, do you sell a living soil product?” Question from Glenn of Leland, Illinois

Answer: “Living Soils” are considered soils that contain microorganisms that naturally break down organic matter and help support plants. They contain beneficial mycorrhizae as well as other supportive microorganisms from earthworm castings and compost. We have several Black Gold soils and Sunshine soils (our sister brand) that contain living elements, which benefit plants and soil quality. These include:

Products with Earthworm Castings

Black Gold Earthworm Castings: Castings are the waste products of earthworms, and they are rich in beneficial microorganisms. So, all of our products that contain them are living soils.

Black Gold® Natural & Organic Potting Mix: This fertile potting mix contains earthworm castings as well as natural compost and is OMRI Listed for organic gardening.

Black Gold® Waterhold Cocoblend Potting Mix: Formulated to hold water well while also draining well, this coconut-coir-cased blend contains earthworm castings.

Black Gold® Moisture Supreme Container Mix: Holds water well, contains earthworm castings, and contains a controlled-release fertilizer that lasts for up to 6 months.

Black Gold® African Violet Potting Mix and Black Gold® Cactus Mix: Both drain well for specialty potted plants and contains castings.

Products with Mycorrhizae

Black Gold Natural & Organic Ultra Coir: This product contains our proprietary blend of endomycorrhizae, so it is alive and kicking with soil beneficials.

Sunshine® Mix #4 with Mycorrhizae: Drains exceptionally well and contains our proprietary blend of endomycorrhizae.

We hope that this helps you choose the best mixes for your growing needs. If you want a mix with endomycorrhizae and the added boost of castings, then we suggest you purchase some BG Castings to add to the mix.

Happy growing!
