Insect frass is insect poop (like guano or castings). But unlike bats or birds, insect frass actually comes from plants. In all natural ecosystems, insects feed on and digest vegetation and give it right back to the soil in the form of nature’s perfect plant food, insect frass!
Plants benefit insects – insects benefit plants!
Insect frass naturally contains all the macro- and micro-nutrients plants require, including silica. It stimulates a plant’s auto-immune system and protects it from pests and pathogens, such as botrytis, root rot, and stem rot. Insect frass is NOT a pesticide. Insect frass is NOT a fungicide. Insect frass will NOT put insects into your garden. Give your plants all the benefits of insect frass, without the bugs!
Insect frass has a 2-2-2 NPK–and it’s vegan!
For pre-mixing: 1 cup per cubic foot of soil, which will last through the next three weeks. Beginning the fourth week, top dress every seven days.
For top dressing: Sprinkle over root zone, then water in thoroughly.
For transplanting: Add a pinch of frass and mycorrhizae.
For hydroponics: Top-dress any grow media (Rockwool, Coco, Hydroton). Add 2 cups per 30 gallons of water (strain for drip systems). Add directly to reservoir for ebb and flow or flood-to-drain systems.
For root drench: 1 Tbsp to 1/2 cup frass per gallon of water.
For foliar feeding: 1 Tbsp per gallon of water; shake well, strain, and apply.
For tea mixes: 1 cup per 5 gallons of water.
To kill fungus gnats: Lightly sprinkle frass over the entire root zone, AND make a solution of 1/2 cup frass per gallon water, shake and let sit for 30 minutes, strain, and apply as a root drench.
