Plants Grow Faster
Worm castings are chemical-free, contain no artificial pesticides, and can be used to grow organic produce.
No Heavy Metals
One of the big problems that many gardeners and farmers are dealing with is high concentrations of heavy metals in the soil and in fertilizers. Worms actually have the ability to absorb heavy metals like copper, lead, and cadmium from soil. This means that by the time they produce castings, they're heavy metal free. This reduces the likelihood that metals will make it into food sources grown in worm castings.
Will Not Burn Plants
Studies have showed that crops grown in worm castings produce 25% more yield on average. That's a lot of extra crops!
