We are often asked, almost daily in fact, if you can reuse microgreen soil once the greens have been harvested.My old blanket answer was "No". However, we recently ran a test to see if it is possible to grow a decent tray of microgreens in reused soil.We expected some ugly trays of microgreens.But boy, were we shocked!It turns old that in some cases clipping down the old crop and planting on top of the stubble will work.The question, however, is should you reuse microgreen soil. Is there too big a risk of disease?We still recommend not reusing microgreen soil. Regardless of what our testing shows.But check out the results and make your own decision.
