Blueberries need few nutrients, but cannot do without fertilization. Lawn clippings or needle litter, for example, are suitable natural fertilizers. Vinegar is not a fertilizer in the true sense, but is used to improve the soil or substrate.
Is vinegar a good fertilizer for blueberries?
Since acetic acid increases the acidity in the soil or substrate, vinegar as a fertilizer can promote thedevelopment of blueberry bushes. However, caution is advised when using it, as too high an acid concentration can harm the plants, especially in the bed.
Can I fertilize planted blueberries with vinegar?
You can fertilize planted blueberries withVinegarHowever, thismay only be used very diluted (300 ml to four liters of water) to improve the soil because acetic acid increases the acidity of the soil. If too much of the good thing gets into the soil, it not only harms the blueberry, but also neighboring plants, as the acid spreads uncontrollably. That's why you should plant the blueberry bush in special soil for ericaceous plants or rhododendron soil and avoid fertilizing with vinegar.
When and how do I fertilize blueberries in the pot with vinegar?
Blueberries in potscan tolerate vinegar in diluted formto improve the substrate, i.e. increase the acidity. However, to prevent the soil from becoming too acidic, you should check the pH value in advance. Blueberry bushes prefer a slightly acidic environment, which corresponds to a pH value between 4.0 and 5.0 (depending on the variety of cultivated blueberry). For a good mixing ratio, add half a teaspoon of vinegar to one liter of water.
Which vinegar is suitable as a fertilizer for blueberries?
If vinegar is used as a fertilizer for the blueberry bush, its acidity should be between five and ten percent. Table vinegar or apple cider vinegar for household use, for example, has this strength. Vinegar essence is not suitable for fertilizing as it is far too acidic.
