Natural fertilizer from mealworms

100% mealworm frass, dry and ready to use with minimal odor and no burn. Spread it over larger areas or mix with water for indoor and outdoor use.

Key things we want you to know

  • Mix rate: under 1% by volume when pre-mixing into growing media.
  • Apply: by spreader, top dress or mixed with water.

Benefits & Features

  • Plant Support: Supports plant growth under stress.
  • Beneficial Microbes: Contains beneficial microbes for plant growth and production.
  • Clean Profile: No nitrates, heavy metals, methane or nitrous-oxide emissions.
  • Neutral pH: No burn.
  • Easy to Apply: Dry powder, no odor, and water-soluble for hydroponics and fertigation.
  • Contains Chitin.
  • Not a Pesticide or Fungicide: It will not bring new insects into your garden.

Application & Mixing

These are recommendations. Your requirements may differ depending on your specific use and environment.

For best results, pre-mix into a growing media or soil when planting. If plants are already started, mix frass with water and apply as a root drench. Frass can also be applied as a top dressing, in hydroponic systems, as a foliar spray and in transplanting holes.

Application Rates (suggestions only)

  • Transplanting: Add a pinch of frass under the roots.
  • Pre-mix: Add 1 cup per cubic foot (or 7 gallons) of planting media before planting, less than 1% by volume. Beginning in week 2, top dress or use compost tea every 2 weeks.
  • Hydroponics: Add 2 cups per 30 gallons of water (strain for drip systems). Top dress any grow media (coco, clay pellets, etc.). Add directly to the reservoir for ebb and flow or flood-to-drain systems.
  • Top dress: Sprinkle over the root zone and water in immediately. 1 pound per 20 sq ft, or 1 tablespoon per plant, every 2 weeks.
  • Foliar feed: Add 4 teaspoons per gallon of water (1 teaspoon per quart). Shake, let sit for 30 minutes, strain and apply.
  • Compost tea: Add 2 cups per 15 gallons of tea (2 tablespoons per gallon) to achieve a fungal-dominant tea. Apply as a root drench.
