The main types of microbes in worm tea are bacteria, fungi, protozoa and beneficial nematodes (not all nematodes are bad!) The problems of the tea going anaerobic isn’t as high, but then again the liquid isn’t as beneficial for plants. Worm leachate does not have the high population of microbes. The brewing process also needs a lot of care and attention where a constant flow of oxygen is necessary to ensure the tea comes out high in quality. Therefore the tea needs to be used within 8 hours of brewing. Once there is no oxygen in the tea these good microbes will die, and the bad microbes will start to develop really quickly causing your tea to become useless. The downside to this is that the tea can go anaerobic (no oxygen) really quickly. The high population of microbes comes at a price though. Therefore diseases are less likely to grow. The high population of good microbes will give them an extra edge against the bad microbes in competition for food resources in the soil and on the leaf of plants. This high population of microbes in the tea serves a great purpose in rejuvenating the soil it is applied on and helps create a ‘barrier’ against bad microbes. molasses) it will feed the good microbes and the population will grow exponentially. The purpose of this process is to encourage the good microbes in the tea to grow.īy brewing the compost with nutrients and a food source (i.e. What is officially classified as ‘Worm Tea’ or ‘Compost Tea’, is when wormcast or compost is placed in a permeable bag and then brewed with water, oxygen and probably some nutrients.
I will be talking more about worm leachate in the next question.
“Could you please tell me the correct dilution of water to earthworm tea? Which plants benefit the very most by being given it? How often should you give them the diluted tea to get a flourishing garden?” ~ Faye GarnerĪs I have mentioned a few times in previous newsletters, there is a difference between worm tea and worm leachate.
