Let’s talk price… Worm castings may cost more upfront over traditional fertilizer, but they rebuild soil health while feeding plants. Unlike fertilizers that require multiple applications per season, 1 application of worm castings may be all that is needed.
Sold by volume rather than weight - this is because moisture levels vary in worm castings. Therefore, selling by volume ensures you always receive the full amount of this living soil booster.
Premium Worm Castings - Intro Package 1/2 Gallon (Small Box)
$11.97
Worm castings are nature’s most complete soil amendment, created as worms break down organic matter into a rich, living compost. Biology in a box! Often called “black gold,” castings are packed with beneficial microbes, enzymes, and nutrients that plants can easily absorb. Unlike synthetic fertilizers that sterilize soils, worm castings are all-natural, gentle, and safe—there’s no risk of burning plants or harming the soil. They work by improving soil structure, increasing water retention, and feeding the living ecosystem beneath the surface.
Perfect for flowers, fruits, vegetables, and even houseplants, worm castings support stronger roots, healthier growth, and more vibrant blooms and harvests. They help plants build natural resistance to stress, pests, and disease while improving long-term soil health. Free from chemicals and fillers, worm castings nourish both plants and the land, restoring soil the way nature intended—slowly, sustainably, and full of life. The ½ gallon box is perfect for covering 3+ square feet of soil at a ¼ inch thick or placing ¼ cup of the soil amendment into 32 house plants.

Living Potting Soil - 50 quart bag
Our Living Soil Blend is more than a potting mix — it’s a biologically active growing medium designed to rebuild soil health from the ground up. Crafted with a balanced base of potting soil, aeration, premium worm castings, and microbially charged biochar, this blend supports thriving roots, beneficial microbes, and long-term soil structure. Instead of relying on synthetic inputs, plants grown in living soil benefit from natural nutrient cycling and improved moisture retention.
The addition of worm castings introduces beneficial microbes and humus, while biochar provides long-term habitat for soil biology and helps store nutrients plants can access over time. The result is a resilient, balanced soil environment that supports stronger plants, healthier roots, and improved water efficiency — perfect for containers, raised beds, greenhouse production, and home gardens. 50 quart bag fills three 12 inch containers.
Worm Tea - 1 gallon
Our Colorado Worm Farm Worm Tea is a biologically active liquid ‘fertilizer’ - a natural amendment - brewed from premium worm castings to deliver beneficial microbes, plant-available nutrients, and natural growth compounds directly to your soil and plants. This living compost tea helps improve soil structure, stimulate root development, enhance nutrient uptake, and support plant resilience against stress. Ideal for gardens, lawns, houseplants, raised beds, and greenhouse growing, worm tea feeds the soil food web while providing gentle, organic fertility that promotes healthier plants and more productive harvests.
Soil drench: dilute 1:5 with water. Apply directly to soil. As a Foliar (leaf) spray) dilute 1:10 with water and coat leaves (underside and topside). Shelf life after opened 2 - 4 weeks. Best used in 3-4 months unopened. Shake gently before use. Best to apply immediately.
Customer Reviews
“As a backyard gardener with a small 5×6 garden tucked beside the house, I didn’t expect huge results. But after using worm castings on my corn, peas, radishes, and tomatoes, the difference was clear. Everything grew faster, healthier, and the flavor was noticeably better.
I harvested more than I imagined from such a small space — enough to enjoy fresh and even canned much of my harvest for winter. Worm castings completely changed what my little garden could produce.”
— Elaine Tracey, Littleton“We added Harvard’s Century Plant, Blue-Beaked Yucca, and Kintzley’s Ghost to our Denver garden, but after nearly a decade of trying, even our gardener couldn’t get them to thrive. Last year we applied worm castings — maybe a little generously with two 5-gallon boxes — and the transformation was incredible.
Plants we had nearly given up on suddenly exploded with growth. They’re now thriving, full, and so large we may actually need to cut them back. Worm castings truly brought our to life.”
— Anonymous Customer, Denver“I used worm castings in my backyard flower beds and in the pots lining our front porch, adding just a few tablespoons to each at the start of the season. The results were incredible — plants grew thick, lush, and healthier than ever. By mid-June, everything looked like it normally would in late August.
The growth happened so quickly, and now I’m enjoying vibrant blooms all the way through October. Such a small addition made a huge impact — I’ll be using worm castings with all my summer flowers from now on. Customer for life.”
