What Is A Compost Tea?

Garden compost materials are naturally brewed into compost tea to provide liquid fertilizer for plants.   

By brewing compost, beneficial microorganisms, particulates of organic matter, and soluble chemicals are transferred into a filtered liquid form, which can then be sprayed onto leaves and soil to provide a range of benefits to plants.

Biologically-based methods for managing pests, diseases, and plant fertility are increasingly recognized by both conventional and organic growers.

Garden compost is a wonderful product for organic gardeners. It’s not uncommon for them to take it to the next level and make compost tea from that lovely compost. It is sometimes referred to as yogurt for the garden.

There are several reasons why it is so good:

  • Enhancing the nutritional value of vegetables and improving their taste,
  • Producing natural antibiotics against plant pathogens in order to aid plants in fighting foliage diseases,
  • Determining which chemicals are most effective at deterring pests,
  • The plants are able to access more nutrients
  • In order to protect the plants, various contaminants need to be broken down.
  • Choosing beneficial bacteria, fungi, protozoa, and nematodes to outcompete pathogenic bacteria,
  • Bringing nutrient cycles back into balance after harm done by insecticides, herbicides, and chemical fertilizers.

Types Of Compost Tea

It is possible to make compost tea in two different ways. There are two types of oxygen: nonoxygenated and oxygenated.

Non-Oxygenated Compost Tea

In the non-oxygenated version, only compost and water are needed. You will also need an old sock or stocking, along with a bucket or drum.

The steps are as follows:

  • Let the drum sit for about 24 hours after filling it with water. Rainwater does not need to be sat.
  • Put high quality compost in the old socks or stockings.
  • In the drum of water, suspend the sock for about a week
  • Every day or two, stir the bucket well
  • Use cheesecloth or similar to filter the final result if you plan on spraying it.
  • Plants and soil around them should be treated with this product.

Using this quick and dirty method, making compost tea couldn’t be easier.

Oxygenated Compost Tea

If you want to get more advanced after brewing the simple version of the tea and are satisfied with the results, you can make oxygenated compost tea – a bubbling brew of goodness with all kinds of interesting ingredients. As a result, the recipes can become quite complex at this point.

There are many ingredients you can use to make oxygenated compost tea, including worm castings, alfalfa, fish emulsion, seaweed powder, corn meal, nettles, green sand, comfry, rock dust, and much more.

Compost tea that includes manure should not be used as a foliar spray on leaves you intend to eat.
