It has been proven that ash can be useful for some plants. After all, wood ash contains up to 75% calcium, 13% potassium, 7% phosphorus.
In addition, it contains zinc, sulfur, manganese and other microelements that are “favorite” for many representatives of the flora.
But you shouldn’t consider ash a universal fertilizer, since there are still some plants that don’t like it.
Since it reacts with alkali, it cannot be used to feed crops that prefer acidic soil.
These include lingonberries, cranberries, blueberries, viburnum, hydrangea, forget-me-nots, honeysuckle, many conifers, as well as a number of other plants.
But for vegetable crops, ash will be an excellent fertilizer, especially for cucumbers, cabbage, pumpkin, beans, peas and others.
By the way, ash can be added to these plants either in dry form or as part of an aqueous solution.
In dry form there should be about 100-200 grams of ash per square meter.
As for the solution, it consists of ash (glass), 9% vinegar (glass) and 10 liters of water.
This “treat” will especially appeal to tomatoes, which often suffer from blossom-end rot due to a calcium deficiency.
