Systemic resistance begins when part of a plant is attacked by a disease or infection. The salicylic acid (and other biochemical) is then produced by the plant in order to create resistance to the spread of this infection, activating some genes.
In principle, salicylic acid activates the plant’s immune system. Unfortunately, in many cases, the plant is unable to produce sufficient salicylic acid to prevent the spread of the whole plant infection, and the resistance may diminish and cause disease.
Aspirin should only be planted in gardens, only once every 15 days. It has no nourishing qualities but indirectly contributes to the development of plants. It strengthens the immune system of plants. It supports both the photosynthesis phenomenon very well.
When applied, you will see faster, healthier development, reduced parasites and resistance to diseases. As is known, salicylic acid is present in willow branches.
You will do the same thing with willow willow. However, salicylic acid ratios in willow trees are not known exactly. Still, the best seems to be the aspirin obtained from the willows.
