Can You Reuse Microgreen Soil? (The Perfect Solution)



After cutting your tray of greens, you will have a tray of soil with many fibrous roots and stems. The microgreens will not sprout again since you chopped them below the cotyledons. Plus, you probably spent good money or lots of time getting high-quality soil.

So, you may be wondering, can you reuse microgreen soil? The short answer is yes, you can reuse the soil, but only if it’s processed correctly through composting or worm bins.

Composting Microgreen Soil

Making your own compost might be intimidating, given the variety of composting methods today. Given how busy we are, it could feel like just one more thing to do.

Keys to a Good Composting

- Moisture (Same as a  Damp Sponge): The key here  is for the pile to feel moist, not wet. Saturated soil reduces the amount of air available to the microbes. - Air (Oxygen Is Key):  The bacteria in your compost pile use oxygen while they break down the materials in a compost pile.

Carbon vs. Nitrogen Ratio of Compost

A balanced compost pile comprises two types of “food,” carbonaceous and nitrogenous. The ratio in your pile is the key when using these two meals. You will always want to aim for thirty parts carbon to one part nitrogen, which is significantly more carbon than nitrogen.

Let Worms Process the Microgreen Soil

Worms eat a significant portion of the organic matter that has decomposed in good soil on a farm or garden. A worm’s existence consists of eating and passing waste.
