WORMGOLD®, High quality worm castings for improved plant health and growth.

It has been known for more than 100 years that plants can show improved growth when worm castings are applied. Flowers grow bigger and brighter colors, vegetables grow larger and are better tasting. With worm castings orchards produce more fruit and nuts with better taste, and vineyards produce more fruit and higher quality wine. These effects of worm castings have been well documented in the published literature and Wormgold® is dedicated with this website of providing you all the information & research for applied vermiculture.
