Will Compost Tea Decrease Diseases

Turn Kitchen Scraps into Rich Organic Compost Tea

This topic has been evaluated extensively, in reference #3 . There are limited studies about disease reduction by compost tea, and the results are inconclusive.

The concept here is that the tea has a high concentration of microbes. When these are sprayed onto leaves they populate the surface of the leaves to such an extent that invading pathogenic microbes cant take a hold. The good tea microbes out compete the potentially bad ones.

For this to work, the sprayed on microbes would need to colonize the leaves . This requires that the new environment, ie the leaf surface, has enough food for them and the oxygen levels are right for them.

Clearly, the oxygen levels would be high and so you can expect that anaerobic microbes would die out quickly. Anaerobic tea just wont work.

The native microbes on plant surfaces are not well understood. There are anywhere from 1 to 10 million microbes on each 1 square centimeter of plant. Nobody knows what happens when more microbes are sprayed onto the leaf. I cant help wondering why the large number of naturally occurring microbes cant out compete the potentially bad ones and yet the ones sprayed on in the tea will do this??

In summary, there is little scientific evidence to support the idea that compost tea solves disease problems.

How To Use Compost Tea For Healthy Roots

Drenching with compost tea is a great way to quickly deliver organic fertilizer and beneficial organisms from compost to a plants root zone. Simply pour the tea mixture onto the soil in the area below the plants leaves . The liquid tea will carry beneficial bacteria, fungi and other microorganisms down to the area around the roots.

Once there, the bacteria will help unlock nutrients that are already in the soil but were previously in a state the plants couldnt use . The mycorrhizal fungi will create a symbiotic relationship with plant roots that will benefit both the fungus and the plant. In exchange for some of the carbon in the roots, mycorrhizae will extend further into the soil to bring back nutrients for the plant. Some estimates suggest that mycorrhizal fungi can extend a plants reach in the soil by 95%!

How To Use Compost Tea For Healthy Leaves

Did you know that bacteria and fungi live on plant leaves? The foliar bacteria and fungi that are most familiar to gardeners tend to be undesirable diseases and pathogens, like powdery mildew or leaf spot. Although a fungicide or other pesticide treatment can help clear up or stop the spread of the bad microorganisms, these treatments also kill the beneficial bacteria and fungi that live on the leaf surface.


One would think that sterile foliage would be a good thing, but it actually isnt. When leaves are covered with the sort of beneficial bacteria and fungi that are found in compost tea, theres more competition for resources and less space for undesirable microbes to take hold. Rather than treating diseases with fungicides after theyve already taken hold, consider applying compost tea to foliage preventatively at the beginning of the growing season.

Properly brewed compost tea shouldnt burn leaves. However, the ultraviolet rays in sunshine can kill the microorganisms so its best to apply before 10 am or after 3 pm during the long days of summer. A standard garden pump or backpack sprayer can be used, although a concrete sprayer will be just as effective and better able to handle the occasional solids that make it through a strainer. Its fine to dilute compost tea as long as the water used is free of chlorine . Apply liberally to the top and bottom of leaves.

It only takes about 24-36 hours to make either kind of compost tea noted above. Any longer than that and your concoction will be in danger of collecting some not-so-friendly bacteria like E. coli and salmonella. The microbes within will use up all the oxygen, which creates anaerobic conditions, and increases the likelihood that bacteria, viruses, and molds will thrive.

What Time Should Gap Compost Tea Maintain

Maintaining the 14 to 30 days gap during the use of compost tea on your plants is essential. Only if it is the growing season of the plants can you use it further. If you want to have the maximum benefits, then you should achieve thorough leaf coverage. The best time for the compost tea to apply is in the morning when the application of compost tea uses the potential of the plants and the sunlight properly.

Theres nothing as burning or making dead plants for misusing the tea. It is suggested to maintain the correct ratio to take the appropriate amount of nutrients from the compost tea. It can have good growth and development for the plants.

Recipe For Compost Tea

Gathering Brown and Green Materials

Both carbon-rich brown materials and nitrogen-rich green materials are needed to create compost. Brown materials include dry or dead leaves , wood ash, garden debris, and wood chips. Green ones are generally leaves, grass, vegetable wastes, and scraps and peels of fruits.

Mixing Brown and Green Materials

To create compost, you need to mix at least two parts brown materials with one part green materials. You need to break all these materials into small parts, then add some soil from your garden. Once you are done, start adding water to moisten the mixture.

Adding Water to the Compost

It is a good idea to add water to the compost once in a while to ensure that you are maintaining the moisture level it needs. Just make sure not to overdo it. Also remember to add kitchen waste and dry leaves once in awhile. The compost should be ready in as little as 3 months and will last as long as 1 year.

Filling the Container with Compost

Straining the Compost Mixture

How To Brew Compost Tea

At this point, youve finished the setup and only need to maintain it over the next three days. This involves stirring the mixture again at least 2 to 3 times a day. This helps loosen the organisms that are growing from the compost and float them into the water to make the tea.

Remember, every time you stir, you will need to reposition the tubes with the bubblers, as these will be dislodged with the motion. Its important that these are always at the bottom, so your tea can bubble up over time.

You also need to remember that using the compost brew is time sensitive. If you find that youre unable to finish the process on the third day, youll need to add more molasses. If you dont, the organisms you want to add to your awesome garden through the compost tea will go to sleep for lack of food. You need them awake and active if they are going to do any good.

    Compost: Yes You Can Make It Yourself

    November 5, 2019 by fifthseason

    -Sally Watkins-

    Compost is all the rage in the sustainability and permaculture communities, but what can compost do for you and your home garden, and how can you produce it on a small scale? In this blog post, we are going to discuss how to get your compost tumbler or pile to create rich, nutritious compost as efficiently as possible, and finish up with a great recipe for compost tea.

    If you have a yard with some space away from your house, the simplest way to compost is to create a basic compost heap. You empty out your food waste onto the heap, mix in a bit of surrounding soil, cover with leaves, and keep layering in this manner until you have a decent sized-pile that will break down into compost.

    We recommend eventually having two piles: One that you are actively adding to, and one that is breaking down into great stuff for your garden. Youll want to occasionally turn your resting pile so that the ingredients will mix and it will break down evenly. When you remove all the compost from the finished pile, make that into your new active pile, and let the formerly active pile rest and decompose.

    For food scraps, its easy to collect them in a countertop compost holder, and then add a few days worth of waste at a time to your tumbler or heap. Our countertop compost keepers have a built-in carbon filter, which is a lot better than the old jar I used because it would still smell sometimes.

    Why Use Compost Tea

    Brewing Compost Tea

    According to Benjamin, who also assisted in compost research studies at Oregon State University, compost tea filters down to the root system and adds to the microbial life in the soil.

    The microbes will kind of get attracted to the root zone and feed off that the roots are releasing, and then in turn they’ll break down nutrients in the soil, making them more available to feed into the roots, and also protect them frompowdery mildew, damping off, and other soil-borne diseases.

    Compost tea also helps with disease suppression when added to foliar feeding .
