Choosing the type of kitchen waste for liquid fertilizer

Choose only wastes like vegetable peels, damaged fruits, left-out leafy vegetables that can decompose easily. Do not add animal product wastes as this can invite maggots and smell very bad. You need to keep in mind that your waste should be decomposable in water after you keep it for one to two weeks.

Loosely close the bucket with a cover and keep it outside where sunlight falls. It may take more than a week to get the liquid fertilizer from the waste. When the microorganisms in the bucket start decomposing the waste you may get bad smells from it. You can use a face mask to deal with the bad smell of the waste.

Collecting the liquid fertilizer for use

You can collect the liquid fertilizer after a week, that is the perfect time to collect as kitchen waste contains different compost with different composting life. If you live in a hot place where the temperature is high, the process may be quicker. It is advisable to stir the waste on an alternative day to help the decomposing process faster. Collect the liquid waste which is dark in color using a mesh after a few days. You will need to add about ten times of water to the final collected amount of the liquid waste. This will dilute the alcoholic content of the waste if any built up during the process. This liquid is rich in many nutrients.

Use this liquid fertilizer to your indoor plants, outdoor plants, kitchen garden once a week to see a good result.

    • Did you dilute the liquid before applying? You need to add about ten times of water to the final collected amount of the liquid waste. This will dilute the acidity of the liquid fertilizer.
