Our Sustainable Approach

We think that healthy soil is the foundation for healthy plants.  Our circular approach transforms mealworm frass into useful plant nutrition, reducing waste while returning valuable organic matter to the soil.

Frasstgrow can be mixed into potting soil or applied as a top dressing. Simply scoop, sprinkle, mix lightly into the topsoil and water your plant.

Made for Indian Home Gardens

    "My apartment courtyard rose bushes was completely mealybug ridden every monsoon. After blending 100g frass into the high clay soil, the leaves returned so thick that bugs literally don't settle. Stunning."

    "बहुत अच्छा organic frass fertilizer है। मैंने इसे अपने indoor plants और flowering plants में इस्तेमाल किया। मिट्टी पहले से ज्यादा healthy लग रही है और पौधों की growth भी बेहतर दिख रही है। इसका smell भी बहुत ज्यादा नहीं है, इसलिए घर के पौधों के लिए भी अच्छा है। Natural और easy-to-use fertilizer है।"
