Garden Gold (1 kg bag)

Mealworm frass to fertilize your plants and garden

NZ$10.00

The "poo" that comes from my organic mealworms is called "frass".  It is an incredible plant fertilizer - hence it's name of "Garden Gold".

Mealworm frass enriches gardens by acting as a nutrient-rich, organic fertilizer and a plant-strengthening bio-stimulant, improving soil fertility, water retention, and plant resilience against pests and diseases, especially through its unique chitin content. It can be applied as a topdressing, mixed into soil or potting mixes, brewed into a liquid compost tea for foliar feeding, or added to hydroponic systems.  

How to Use Mealworm Frass in Your Garden

  • Soil Building & Potting Mixes: 

    Mix 5–10 tablespoons of frass per 10 liters of soil. 

  • Topdressing: 

    Apply 3–6 tablespoons per plant or approximately 0.5–1 liter per 10 m² every 2–3 weeks during the plant's active growth period. Water thoroughly after application. 

  • Compost Teas: 

    Add 1–2 tablespoons of frass per liter of water to create a compost tea. Brew for 12–24 hours, then use as a root drench or foliar spray. 

  • Foliar Spray: 

    Steep frass in water (about 1 tablespoon per liter) for 30 minutes, strain it thoroughly, and spray it on the leaves during early morning or evening. 

  • Hydroponics: 

    Incorporate frass into hydroponic systems as a top-dress at 5 tablespoons per plant or add 1 tablespoon per liter of reservoir water after straining.
