Vermiculture or worm farming is very important in natural gardening. This natural fertilizer produced by worms contains three times as many nutrients as the soil itself, and comes with a team of helpful microbes to keep your plants healthy and green, retain nutrients longer, and to fortify the soil they reside in. Plants enriched with vermicompost typically yield spectacular improvements. Vermicompost tea has been shown to cause a 173.5% increase in plant growth by mass over plants grown without castings. These results were seen with only 10% addition of castings to produce these results.
