What makes Ash useless and even harmful fertilizer? I advise everyone to read it, do not make my mistakes
Recently, it seems that almost all gardeners and gardeners use ash! So much is said and written about it - environmentally friendly, cheap, universal for many cultivated plants! But not everything is so simple with ash. From my own experience, I was convinced that she is capable of not only helping, but also harming on the site!
Many people value ash for its high potassium and calcium content. But in principle, during periods when plants require these elements, you can use other fertilizers, because ash is absorbed very slowly.
That is, in fact, adding only it and hoping that the strawberries will ripen sweet, and the spinach - savory, is simply useless.
Several times I have come across recommendations that ash can reduce soil acidity. But the fact that the soil becomes not only more alkaline, but also much poorer in nitrogen content is usually not mentioned!
And if something is planted in such a place, then the plants at the beginning of the growing cycle will not have the main substance for the growth of green mass and the development of the root system.
Introducing nitrogen as a separate fertilizer is again pointless. Because the ash will not allow it to be fully assimilated.
Ash cannot be added to soil mixtures for germinating seeds for seedlings - as a result of complex chemical reactions, ash is thus affects the seeds of most garden crops, including bell peppers and eggplants, which greatly decreases in them germination.
Ash, by the way, is very harmful to crops that prefer acidic soils. These include:
• roses, nasturtiums, chrysanthemums, ferns;
• blueberries, raspberries;
· Beets, cabbage, carrots, eggplants, melons and all legumes.
I lost the green peas precisely because of the ash!
Another bad advice is to dust the cuts with ashes after pruning plants, for example, strawberry bushes, peonies at the end of summer.
Indeed - ash, with such contact with plant tissues, enhances the processes in which chlorophyll is involved, accelerates the regeneration of damage. But at the same time - it very weakly protects plants from fungal diseases.
If you hope that in a cold and damp spring, ash will protect the young roots of seedlings from rot, then you can completely destroy it - because ash will only cause them to burn.
Perhaps someone uses ash in a way that doesn’t harm. But personally, I think it's better to give it up!
