Planting blueberries in the garden is becoming increasingly popular because the blue berries are one of the superfoods. The berry bushes do not require any special care, but are picky when it comes to soil. Not every primary rock soil is suitable for blueberries.
Can blueberries tolerate primary rock flour?
Primitive rock flour is a soil improver that should be used on blueberries under certain conditions. Strongly alkaline soils can be acidified with granite or bas alt flour so that the blueberry plants feel comfortable.
What is primary rock flour?
Primitive rock flour is not a fertilizer in the true sense, but rather a soil improver. But since it consists of crushed stones, it also contains minerals that plants need for their growth.
Which primary rock flour can you use for blueberries?
Basically, the blueberry only tolerates rock dust, which acidifies the soil. Rock dust, which is used for soil acidification, for example, is harmful to cultivated blueberries.
How do I recognize primary rock flour that is suitable for blueberries?
When buying primary rock powder, pay attention to the manufacturer's information. You can find this on the packaging or in the form of a technical data sheet. As a rule, the manufacturers expressly point out that the primary rock flour is not suitable for blueberries. If it is not suitable for azaleas and rhododendrons, it should not be used for blueberries either. Another feature is the pH value, which must be well below 8.5 so that the rock powder does not contain too much lime.
Tip
Fertilize blueberries
Horn meal, needle litter or dried coffee grounds can be used to fertilize blueberries. Conventional compost is not tolerated by the berries.
