Wood ash is a natural fertilizer, and there is no need to prove its beneficial properties to anyone.
When burning vegetation and firewood, ash remains, which contains potassium and other substances useful for plants. But we must not forget that ash is also a soil deoxidizer.
Anastasia Kovrizhnykh, an expert of the online publication BelNovosti, a scientist, agronomist and landscape designer, told which beds should not be sprinkled with this fertilizer.
Benefits of Ash
Ash contains calcium, potassium and phosphorus, which are useful for fruit plants, as well as magnesium and a number of other microelements.
At the same time, ash is often used to combat insect pests.
It improves the composition of the soil and helps fight pathogens.
Thanks to its disinfectant properties, ash can be used to treat plant cuts.
Harm of ash
Ash can interfere with plants that prefer to grow in acidic soil.
Therefore, this fertilizer is not applied to blueberries and sorrel, but from ornamental crops, to azaleas and hydrangeas.
It is also important to remember that ash obtained from burning grass and leaves, as well as bark and branches, is more beneficial for plants.
And wood ash contains significantly less potassium than is necessary for many fruit crops.
