How experienced gardeners acidify soil for blueberries: vinegar and citric acid are not an option
As you know, when growing blueberries, the pH of the soil is of decisive importance - the plant prefers to grow in an acidic substrate.
As the expert of the online publication BelNovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh explained, the optimal pH values for this crop are 3.5-4 units, possibly 4.5.
If the pH of the substrate exceeds 5.5-6 units, then you will have to get acquainted with chlorosis on blueberries.
Of course, it is impossible to talk about a decent harvest of berries in this situation.
To acidify the substrate in which blueberries grow, gardeners use a variety of means.
Sometimes citric acid and vinegar are used, but it must be admitted that these products are rather weak acids, which is why they are simply not capable of acidifying the substrate sufficiently.
If you are faced with a similar problem, try using colloidal sulfur to solve it.
If we are talking about young bushes, then 50-70 g will be needed, those plants that are 2-3 years old need 100-150 g, and for bushes that have crossed the three-year mark, 200 g of sulfur per square meter is required.
Fertilizer should be applied once a year - this amount should be enough for the entire season.
