Blueberries are rarely found in private gardens, but growing them can be worthwhile. cultivated blueberries (Vaccinium corymbosum) can produce substantial yields, reaching up to four meters in height, and can supply an entire family's blueberry needs. Proper fertilization can have a supportive effect, so that many of the healthy and delicious berries can grow on the shrub in the long term.

When is the best time to fertilize blueberries? How do you fertilize and which fertilizers are suitable for blueberries? In this article, we explain how you can optimally supply the heather plant (Ericaceae) with nutrients.

The right time to fertilize the blueberries

Blueberries can be fertilized several times a year so that there are enough nutrients for the plant during the growing season. When planting, work acidic natural fertilizers (coniferous litter, pine wood) or an organic commercial fertilizer into the soil. In the following years, the first application of fertilizer is always in spring (March) to promote the growth of young shoots. During flowering and fruit formation in June, a second fertilization serves to ensure a high yield. It is best to use organic long-term fertilizers such as our Plantura Organic universal fertilizer. These provide your blueberries with nutrients over a longer period of time and are also particularly gentle on plants, soil and animals in the garden.

Summary: when to fertilize blueberries/blueberries?

  • Work in some acidic natural fertilizer when planting
  • Annual basic fertilization in spring (March)
  • Second application of fertilizer for flowering and fruit formation in June

The right fertilizer for blueberries/blueberries

Blueberries need acidic soil with a pH of 4 to 5 for healthy growth. Therefore, when choosing fertilizer, make sure not to use calcareous fertilizers, as they increase the pH value too quickly. In the following we give you an overview of which fertilizers are best suited for blueberries or blueberries.

Fertilize blueberries/blueberries organically

When growing blueberries, the use of natural fertilizers makes sense, since the shrub also has a large amount of organic material available in its natural environment. Mulching and working in needle litter, leaves, pieces of bark and lawn clippings has proven itself as an organic fertiliser, which contributes to the long-term supply of nutrients to the plant. When planting the shrub in the garden in particular, you should think about incorporating the natural material. In addition to the long-term supply and better water storage in the soil, the use of organic substances is also recommended from an ecological point of view.

Our Plantura organic universal fertilizer consists for the most part of organic, vegetable raw materials that are slowly decomposed by the microorganisms in the soil. Due to the balanced nutrient composition, this fertilizer is suitable for all plants that do not have an increased need for potassium. A high proportion of nitrogen promotes the growth and leaf formation of the berry bush at the beginning of the growing season in spring. Sufficient potassium and phosphorus also promote subsequent flower and fruit formation. To ensure that you supply your blueberries with the right amount of nutrients, we have prepared precise fertilization instructions for you below.

Organic long-term fertilization: instructions and dosage amounts for bilberries/blueberries

  1. Before planting: About 80 - 160 g/m² (6 to 13 heaped tablespoons) of our Plantura Organic universal fertilizer work into the ground
  2. Water the soil and the bush used well so that the granules can loosen
  3. Fertilize about 60-120g per plant (5-10 tablespoons) every spring (March).
  4. Small doses of fertilizer for flowering and fruit formation (June) provide optimal support for your blueberries

Fertilize blueberries/blueberries with minerals: Blaukorn and Co.

blue grain, liquid fertilizer and Co. are often used for fertilization in the garden, since the nutrients are available in their pure form and can be absorbed directly by the plant. However, if used improperly, the high concentrations of nutrient salts can quickly lead to over-fertilization of the plant. This can lead to both damage to the sensitive plant roots and leaching into the groundwater. Organic Fertilizers Although they work more slowly, they are much gentler on the environment and, if used correctly, support the development of your blueberry bush more sustainably.

Fertilize blueberries with coffee grounds

A particularly clever way to naturally fertilize blueberries is to use Coffee grounds as fertilizer. Because coffee powder also offers many advantages for use in the bed after brewing. For example, the home remedy contains many plant-important nutrients such as nitrogen, phosphorus and potassium. Organic materials also attract beneficial insects such as earthworms and promote the formation of humus in the soil. Pests, such as snails, on the other hand, are kept away. In addition, the acidic natural fertilizer ensures a low pH value in the soil and is therefore perfect for fertilizing blueberries.

Tip from the pro: Dry the coffee grounds before using them to prevent mold from forming during storage. Sprinkle small amounts of it on the soil as fertilizer and work it into the surface.

Not just fertilizing, that too Cutting the blueberry is an important part of care. You can read about what needs to be considered in our special article.
