How To Make Compost Tea, A Superfood For Your Garden
‘Compost tea’ is a brewed drink for your plants that’s packed with nutrients and living organisms to help your garden thrive. But this isn’t your average fertilizer, compost tea works differently, as it feeds the soil first and not just the plants. It’s easy to make, and once you start using it, you’ll wonder how your garden managed without it. Here’s how to get started with compost tea, and what makes it worth the effort.
What Compost Tea Really Is
Compost tea, thankfully, isn’t a complicated concoction. There are only two ingredients, clean water and finished compost. The water pulls out the nutrients and beneficial microbes in the compost, then you spread that rich mixture over your soil or spray it on your plants. Think of it as brewing live bacteria, fungi, and nutrients, everything your soil needs to stay active and alive. It’s not the same as dumping compost straight into the ground. This is faster and more targeted, giving your plants a dose of exactly what they need, exactly where they need it.
Choosing the Right Compost
Don’t just grab any pile of compost, though. The quality of it does matters It needs to be “finished,” meaning completely broken down. Only go for compost that’s dark, crumbly, and earthy smelling. If you’ve made your own, that’s even better since you’ll know what’s in it. Store-bought compost is fine too, but try to find one that’s organic and not sterilized. The goal is to get as many living organisms as possible into the tea, and that only happens with active, finished compost that’s been well-cared for.
Brewing It The Right Way
There are two ways to make compost tea, simple soaking or aerated brewing. For a basic version, toss a few shovelfuls of compost into a bucket, add water, stir once or twice a day, and let it steep for a couple of days. If you want to go further, use an aquarium pump to keep oxygen moving through the mix, that helps beneficial microbes multiply faster. Either way, strain it before you use it. You want a dark, earthy liquid, not sludge. It’s that liquid gold your garden will love.
How (and When) To Use It
You can pour compost tea directly into the soil around your plants or spray it onto leaves as a foliar feed. Early morning or evening is best, especially if you’re spraying. Avoid doing it during full sun or right before rain. Aim to use it within a few hours of brewing, since after that, the microbes start to die off. For best results, apply every couple of weeks during the growing season.
What Compost Tea Doesn’t Do
Compost tea isn’t a miracle. It won’t fix poor soil overnight or bring a dying plant back to life. What it does is support healthy growth and help plants resist disease, but it only works if your soil is already somewhat healthy to begin with. Think of it as part of a bigger picture. Compost tea works best alongside mulch, compost, and proper watering. The goal with compost tea is long-term soil health, which will sustain a stronger garden.
