Worm Tea, also known as Worm Juice or Worm Wee. No matter what you call it, it is the liquid that leaches out of your worm farm or worm castings that are added to water. (Remember to always use rain water and if you are using town water, let it sit overnight to allow the chlorine to evaporate.)
The microbiology of fresh worm castings and worm tea create amazing results when used on plants and soil. These beneficial microorganisms ward off fungi and disease by adding vitality to the leaves and roots. It also provides you with a chemical free product which is more effective than any other product you find in the store.
Worm tea can be diluted and sprayed all over your plants and food crops. I have used it on Lillipillys to eliminate sooty mould and it even help the plant fight off Lace Lerps which have just dried up and fallen off. Pretty soon the Lillipilly which was on a serious decline was flourishing with new growth.
Worm Tea is a great addition to an irrigation system using sprinklers or drip irrigation providing the solids are filtered out. It is also used by farmers on orchards with boom sprayers, a welcome relief from chemical fertilizers which require chemical safety procedures and PPE.
Or you could add it straight to your water tank in your backyard and then use your pump and garden hose to spread the goodness to your plants that way!
Hope I have given you some ideas to build on! :-)
