Mealworm Frass is a powerful soil amendment from The Soil Makers designed to strengthen plants, boost natural defenses, and foster a thriving soil ecosystem. Derived from Mealworms, this amendment enriches soil with enzymes and chitin that trigger plant immune responses, support robust growth, and help suppress common soil pests.

What it does for your garden

• Activates plant defenses through chitin recognition, helping plants respond as if under insect attack while building stronger cell walls and biomass.
• Supports a vibrant soil biology by nourishing beneficial microbes and enhancing nutrient cycling for steady growth.
• Helps reduce populations of root-feeding nematodes and aids in managing fungal diseases for healthier roots.
• Acts as a natural bloom stimulant, promoting vigorous overall vitality in container plants, beds, and indoor gardens.

How it works, simply put

• Chitin from the frass signals plants to bolster their immune systems and build resilience against pests and diseases.
• Soil biology benefits from the organic matter and minerals in the frass, creating a more active, balanced microbiome.
• Improved root health and biomass support more efficient nutrient uptake and stronger top growth over time.

Usage guidelines (per the line between soil health and growth)

• New or existing soil: incorporate 3/4 to 1 cup of Mealworm Frass per gallon of potting soil.
• Established plants: spread 2 tablespoons around the base before watering for ongoing nourishment.
• Root drench: use 1/2 cup per gallon of water every 3–4 weeks to maintain root health.
• Compost tea (soil microbial boost): mix 10 tablespoons Frass with 1 cup worm castings in 5 gallons dechlorinated water; aerate 24 hours before use.
• Foliar spray: dissolve 1–2 tablespoons in 1 gallon of water, strain, and mist leaves; apply about 30 minutes before lights or in cool, early morning hours for maximum uptake.

Ideal for gardeners who want healthier soil biology and stronger plants—whether in pots, raised beds, or traditional garden plots. It’s a natural choice for indoor green thumbs and outdoor growers aiming to suppress soil pests like fungal gnats while fostering robust growth.
