When compost tea may fit your garden routine

  • When you want the compost-tea approach without brewing a bucket and aerating it for days
  • When beds or containers are already on a fertilizer schedule and you are adding to it, not replacing it
  • When a hose-end sprayer is how you water and the 2 teaspoon setting fits what you already do
  • When you would rather apply something with every watering than keep a separate calendar

This carries no guaranteed analysis and is not a fertilizer — it supplies no stated nitrogen, phosphorus or potassium, so keep your plants on the feed they are already on alongside it.

Frequently asked questions

How often should I use compost tea?

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.

Is this the same as brewing my own compost tea?

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.

Does compost tea replace fertilizer?

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.

How should I handle Compost Tea around children, pets, and vegetables?

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.

Can I use it on houseplants and lawns too?

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.

When will I see results?

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.
