Is compost tea estimable for plants ? Should I make it for my garden ? countenance ’s look at what is sleep with about compost tea and what — if any — value it has for improving ground and feeding plants .
This topic is part of an on-going series where we reckon at common garden advice to learn whether there is science to back it up . SeePopular Garden Myths We ’ve All Fallen Forto learn more .
Compost Tea For Plants
When you first hear about compost teatime , the idea seems ordered .
Take some compost — the same compost we utilise to enrich our garden soil — leave it in a bucket of water , come after one DIY method or another , and eventually you ’ll have a instinctive , limpid provender quick for your plants .
Seems logical , right ?
And by having the nutrient in melted form , you ’d seize it attain works theme faster , delivering the nutritional benefits sooner .
Some even claim it ’s more nutritionally heavy than regular compost .
But is this true and does it really work ?
Let ’s see what is recognize about compost tea leaf and why it ’s not what it seems .

The Problem With Studying Compost Tea
The biggest challenge with compost tea and trying to research its effectiveness is that compost tea is not one uniform thing . In other word of honor , no two homemade compost tea brews will be the same .
It ’s not likeEpsom saltwhere your Epsom Strategic Arms Limitation Talks is the same as mine and both of ours are the same as anyone else ’s in the world . We may have different impurity , but for all of us the actual Epsom Strategic Arms Limitation Talks is the heptahydrate form of magnesium sulfate . And because it ’s constant , we can try out it .
construct compost tea leaf is like make homemade soup with whatever you have on hand . Each is different and unacceptable to compare .
No such circumstances with compost tea leaf . It bug out withcompostand your compost is not the same as mine . And the compost you made this twelvemonth is different than the compost you made last year . It ’s blend to vary by what you add to the mountain , as well as oxygen levels , temperature , humidity , and other factors .
On top of that , there are so many different methods for making compost tea . It may be as simple as locate some shovelfuls of compost in netting and let it sit and turn in a bucketful of water for a few workweek . Or , it may involve aeration with pumps and hose to “ oxygenise ” the brew . Or some other combination of steps .
And with so many variables , there is no standard compost tea to quiz .
But so what ?
If the thought is to turn compost into melted feed for plant life , does it matter that the composition varies each time ? Are n’t the plant still get under one’s skin superfluous goodness ?
And does n’t this provender works more efficiently than regular compost ?
Not that we screw of .
Most of the benefits that are claim for compost tea can be achieved by just using compost .
Here ’s why .
By Diluting Compost You Get Low Nutrient Levels
There is no question that there are nutrients in compost including H2O - soluble nutrients that can easily make their way into a compost tea .
But the punchline is , it ’s not a very high tightness of food , no matter how it ’s made .
Compost is still the grunge amendment of alternative for those of us who want to ameliorate our grease on an ongoing basis without relying on syntheticfertilizers , but the fact is , no matter how it ’s made , those nourishing degree are low .
Turning compost into compost tea does n’t change the values . It just becomes a low assiduity of nutrients in liquid form .
But wo n’t the teatime deliver what food there are to the soil faster ?
Not really . From what we eff , it ’s not much unlike than tot up compost to your dirt and watering it .
I have several garden friends who swear by compost tea — and who does n’t rely on our own experience oranecdotal evidenceto lead some of our garden decisions ?
But , after earn how scant the food would be — which is something science has reassert — it makes me question if it ’s their paying attention handwriting - watering that is really help oneself rather than any substantial eating hold up on .
Just recollect about how much compost would go into a batch of compost Camellia sinensis . How much nutritionary value could we really look from a shovelful of compost ?
There could also be somemicrobial activity , either beneficial or pathogenic , but it will disagree with each batch and you ’d have no way of measuring it at place .

If Compost is Available, Use It
Dr. Elaine Ingham , one of the best - known proponents of compost Camellia sinensis over the past twenty days , says this in hermanual on aerated compost tea :
How do we get “ the full diversity of bacteria , fungus , protozoa , nematodes ” and so on in our soil?It ’s call “ compost ” , she write . “ Or compost tea , if the author of compost is distant , and transportation cost are too high . ”
In other words , just recur to using compost tea if for some reasonableness you’re able to not get at regular compost for your garden but do have compost tea available .
There is fiddling note value in compost tea leaf if you already have goodish grease and regularly hold compost .
Ingham has say in interviews that she sees compost tea as being great for helping plow hapless grease into something good for you — maybe for the first year or two if you have poor filth , but even she has said that there may be little value in it if you already have healthy dirt and regularly give compost.[8 , 9 ]

Future Studies
Increasing Microorganisms
We know the alimentation levels in both compost and compost tea are low but what about the microorganisms ? Maybe there is something useful there ?
While some microorganisms are pathogenic ( harmful ) , great deal of others help plants in many different shipway let in disease bar .
Some study are look at manifold the number of microorganism in compost tea using sugars or other foods as accelerants .
There is also experimentation with unlike recipes and method acting to see which brings the high concentration of the micro-organism you desire and fewer of the ones you do n’t .
There wo n’t ever be a cosmopolitan teatime , though , because what is suitable varies by works and place .
But perhaps there will be some micro-organism - specific compost teas in our future .

Foliar Spray
One potential advantage compost tea has is that it can be used as a foliar atomiser and apply directly onto leaves and other shoots of plants which you could not do with compost .
There have really been many study where compost teas have been prove to be in effect in struggle particular diseases in some industrial plant and even in improving growth .
But there have also been many tests where there were no improvements at all and some where the compost tea even made things worse .
This is n’t surprising given the variability of compost tea .
We should also mention that none of the studies have been done in gardens . Many are done in labs or other environments in limited content , using agrarian inputs like creature manures , making it quite a leap to go for the findings to our own gardens .

Summary
As it is today , we ca n’t see any intellect to expend compost tea as an ongoing , general treatment for plants .
There ’s certainly some aspects worth further cogitation , but nothing to preach for compost tea use until more research is done . We may finally find specific applications require specific brews , not the random mix we ’ve prepared at plate . If you have compost , just employ compost , and save yourself some work .
If , however , by using compost tea it generate you to more attentively hired man - water your outdoor plants — and they call for it — by all means , go for it .
Unless you ’ve concocted some funky brew , it ’s all the same to the soil .
