Worms eat organic waste and turn it into liquid fertiliser and worm castings (the organic material that has been digested by the worms). Both of these products can be used on your garden and on your pot plants to keep them thriving.
You can use worm liquid to replace fertiliser. The liquid needs to be diluted until it is the colour of weak tea. This mixture won’t burn your plants. You could bottle your excess liquid and give it as a gift with instructions on how to use it.
Composting is another great way to reduce organic waste and improve soils.
