Using SCOBY’s to balance garden pH


Anyone who makes a fair amount of kombucha will know what it is like to have a SCOBY surplus! My SCOBY hotel has no vacancy and I can’t give them away fast enough. Maybe I should sell them! Well, I decided to explore my options. I can’t throw them away because I grew them, they are like my little SCOBY babies.

One day while reading about pH balancing the soil in my garden I thought, maybe my SCOBY’s could help with that! Now, my tomatoes are happy….and I didn’t have to waste any of my precious kombucha spawn.

Here is a chart that shows plants affinity for acid or alkaline.

SCOBY’s are acidic so I decided to put them around my tomato plants. Also, those were the biggest plants in my garden at the time of my little experiment.


Here’s how I did it:

Cut your SCOBY into smallish pieces using a kitchen shear or a large knife


Place the SCOBY pieces around the base of the plant


Cover with dirt


Watch them grow!!!

    I would love to read a follow up on this. Did it seem to help or hinder the tomato plant any? Our extras go the chickens. They go crazy for the scobys.

    It looks like you simply set them around the base of the plant. Then, we see nothing around the base of the plant in the next pic. Or, at least I don’t.

    Did you dig them into the dirt a bit or what?

    I also am doing an experiment. After cleaning my garden this fall, I blended some SCOBYs with water, then diluted about 4C water to 1 C blended mix) (original mix was about 4:1 also) Then I watered all the parts of the garden that were empty. Hopefully that will help the soil to balance over winter. Then, In the spring, I will make the same mixture and water with it around the base of my perennials. I did use a similar mix in the garden this summer on already growing plants. I had the best garden ever! Ex. I usually get about 1 1/2 peppers per plant. This year I got at least 6. Yippee! I often have extra SCOBYs also. I just keep a closed bottle in the frig with a bit a boucha liquid. It keeps a long time. I've kept them about 3 months and they're fine.


  1. […] *Note from Kate: I would personally use my dehydrator to make these because there is a door that covers them and no pests can get in. HERE is the dehydrator that I use and love, love, LOVE. But, if you do not have a dehydrator, you can use the oven as well. Want to read about another trick to use up extra SCOBY’s? I use them in my garden! […]
