Our Compost Tea is a ready-to-pour liquid made from earthworm castings compost tea, with citric acid to hold the pH steady. It is not an NPK fertilizer and carries no guaranteed analysis. Mix 1 to 2 teaspoons per gallon and water your garden evenly, on its own schedule or alongside your usual feed.
Compost tea is traditionally brewed at home — compost, water, a bucket and a day or two of aeration — and the brewing is the part most people give up on. This is the same input in a bottle you can pour, made from earthworm castings tea rather than brewed on your patio.
How do you use liquid compost tea? Mix 1 to 2 teaspoons per gallon and water it evenly over the soil. It can go on once a week, or with every watering, right through the year. On a hose-end sprayer, use the 2 teaspoon setting.
What it is not is a fertilizer. There is no guaranteed analysis on this product and no NPK figure — no nitrogen, phosphorus or potassium number — so it does not take the place of whatever you feed your plants with. Treat it as an addition to a feeding routine rather than a substitute for one.
Why growers choose it: Earthworm castings compost tea already in liquid form, at a simple 1 to 2 teaspoon rate, with no brewing and no equipment.

Compost Tea is a biological input rather than a fertilizer, so it doesn’t follow a seasonal feeding schedule. Mix 1 to 2 teaspoons per gallon of water and water your garden evenly, either once a week or with every watering, all year round. A hose-end sprayer set to the 2-teaspoon setting covers beds and lawns quickly. The easiest habit is simply adding it to the can whenever you water; it can go in every time.
Same idea, without the equipment or the 24 to 48 hour wait. Home brewing steeps castings or compost in aerated water to extract microbes and humates. Compost Tea arrives with that work already done: earthworm castings brewed into liquid and stabilized with citric acid so the pH holds in the bottle, ready to pour. If you enjoy brewing, the two work well together; many gardeners keep the bottle for regular waterings and brew batches for big spring applications.
No. Compost Tea carries beneficial bacteria and humates, but only the light nutrient load that worm castings naturally hold. A hungry tomato or a depleted bed still needs nitrogen, phosphorus and potassium from a fertilizer or compost. What the tea does is help that feeding count: the humates help roots absorb minerals and help soil hold nutrients rather than letting them wash through. Use the two together, and each does its own job.
Compost Tea contains earthworm castings tea and citric acid. Follow the directions for your plants, store the product out of reach of children and pets, and rinse your skin after splashes. When using it in an edible garden, follow the application instructions and wash harvested produce before eating.
Yes to both, at the same 1 to 2 teaspoons per gallon. Compost Tea works for every pot in the house; just water normally with the mix. For lawns, a hose-end sprayer on the 2-teaspoon setting is the practical route. The bacteria and humates help thatch break down and improve how the turf uses whatever lawn feeding you already do, so it fits alongside a regular lawn fertilizer rather than replacing it.
Gradually and cumulatively; that’s the nature of a biological input. Used with regular waterings, expect the indirect signs first over 3 to 6 weeks: soil that wets more evenly, plants responding better to their normal feeding, steadier color. The larger payoff builds over a season as soil biology establishes. For a faster, more visible push, pair Compost Tea with an NPK fertilizer; the tea helps roots take up what the fertilizer supplies.
