A while back, the general consensus was that compost tea had zero shelf life. In other words, you made up your batch and were forced to use it immediately. This is the case still if you don’t aerate it.
To improve absorption and get the very best results out of your tea, apply it when the soil and plants are moist. And if you really want to ensure that those beneficial organisms that have been cultivated in your compost remain active, the best time of day is either in the earlier hours of the morning or close to dusk when there are dewy conditions.
Another common question about compost tea is “Can I use it on my lawns?” The answer is yes.
Adding a compost tea into soil prior to planting grass seeds makes for a good foundation for a healthier lawn. You’ll find that the grass will grow quicker, be greener, and less prone to weeds, which is always an added bonus.
Making compost tea is relatively straightforward. The most important thing you need to remember is to use well-aged compost. Why is this imperative? Unfinished compost can sometimes contain harmful pathogens that can cause more harm than good to your plants and vegetables.
Does Compost Tea completely replace other fertilizers? - It depends what you add to the tea while it's 'cooking'. Different stages of the plant's life need different nutrients.
