The nutrients in the herbal infusion are absorbed by the plants particularly actively during the flowering and fruiting period. I will tell you simply and clearly what recommendations the technical science candidate Anatoly Aleksandrovich Veselov gives on this topic.
In order not to use chemical fertilizers on my site, which are quite expensive, and also to avoid using manure, which is not cheap either, I prefer to use natural fertilizers. For example, compost is a great option, but we usually use it when preparing flower beds or apply it directly when planting. But when plants start to turn yellow or fall over, herbal teas come to the rescue. This is a truly economical and effective method.
I tried infusing several herbs, but after a week the infusion began to emit such a strong and unpleasant smell that its use to water plants became undesirable. It was also unclear how much and when it is best to use it.
However, after studying scientific papers, I found answers to my questions. The books describe in detail recommendations for the proper preparation of herbal teas, which herbs to choose, how long the solution should be infused, and how to dilute it properly.
It turned out that not all herbs are suitable for infusion. For example, horsetail, banana, nettle, sorrel, and burdock are excellent. It is important to remove the roots and flowers, chop the grass and place it in a container filling it to two-thirds.
After seven days, the fermentation process begins and an unpleasant smell appears, which after 10 days becomes similar to the smell of manure. After this period, the cap must be put back on a mesh so that the infusion can “breathe”, and after a couple of days it can be used.
