Compost or Worm Castings?

To obtain a high-quality compost, the compost pile must reach a high self generated temperature for an extended length of time. The high temperature is required to kill harmful bacteria and break the organic material down to a level of basic nutrients. The beneficial bacterial will thrive to assist in this operation. Additionally, all grass seeds are killed with none in the end product.

Vermicomposting uses worms to perform the same process of eliminating bad bacteria, promoting good bacteria and breaking organic material into basic plant nutrients with the end result being a much better product called worm castings. The reason being as the worms ingest and digest their surroundings, the harmful bacteria is killed and the beneficial bacteria is enhanced by the addition of special bacteria in the intestines of the worms. Additionally, the worms cover their “poop” with a mucous layer that makes the worm castings “time release” meaning their nutrients are not released all at once. Some grass seeds may survive the process of vermicomposting and screening and be present in the end product. We try to allow ample time for the seeds to germinate prior to the last screening and packaging to eliminate any remaining seeds.

No matter how much compost or worm castings you use, your plants can never be burned as is possible with chemical fertilizers!
