If, on the other hand, you are more of a friend of solid blueberry fertilizers, then we recommend this product. This mineral fertilizer granulate is an NPK fertilizer that is optimally tailored to blueberries, but which only gradually releases its nutrients to the plant. Therefore, fertilizing twice a year - once at the beginning of budding in spring and again after harvesting - is completely sufficient.

Purchase Criteria

fertilizer type

Organic Fertilizer: Organic fertilizers are made from natural raw materials that naturally decompose slowly, allowing the nutrients to be released to the plants gradually rather than all at once. As a result, over-fertilization is hardly possible, and these fertilizers protect the environment and the groundwater.

mineral fertilizer: Mineral fertilizers are synthetic, i.e. artificially produced, fertilizers based on various salts. Their nutrient composition is usually optimized in the laboratory. Since these agents are immediately available to the plants and they are also highly dosed, over-fertilization is quickly possible if the wrong dosage is used.

Organic mineral fertilizer: If you want a fertilizer that both provides nutrients immediately and releases them gradually over a period of time, organo-mineral blends are the right choice.

dosage form

liquid fertilizer: Liquid fertilizers are concentrates that are diluted with the irrigation water and applied. That is why liquid fertilizers are usually available in small bottles of 500, 750 or 1000 milliliters, with one liter of concentrate being sufficient for approx. 100 liters of ready-mixed fertiliser. Liquid blueberry fertilizers are particularly suitable for plants cultivated in tubs, as these have to be watered and fertilized more often anyway and the roots can absorb the valuable nutrients immediately.

solid fertilizer: Solid fertilizers in powder or granular form are usually not dissolved in water, but applied to the soil directly in the root area and lightly worked in. The freshly fertilized plant should then be watered vigorously so that the granules dissolve and the nutrients reach the plants. These fertilizers are particularly good for blueberries that have been planted out.

ingredients

Even if you opt for an organic fertilizer or a mixed form, it is worth taking a closer look at the list of ingredients. Slaughterhouse waste (which incidentally also includes horn shavings (€32.93)) as well as waste and leftovers from the food and animal feed industry are often processed into fertilizers. There is basically nothing wrong with that, after all, these organic substances are fed back into the natural cycle, but some users may be bothered by this.

nutrient content

When looking at the nutrient composition of the blueberry fertilizer, make sure that the proportion of nitrogen is slightly higher than that of phosphorus and potassium, the other two main nutrients. In addition, all minerals and trace elements should be present. However, caution is advised with lime: As ericaceous plants, blueberries are very sensitive to lime, which is why you should never water the shrubs with tap water or other calcareous water.

Frequency of use / duration of effect

Long-term fertilizers are particularly practical, as they provide the plants with sufficient nutrients for three or even six months. Otherwise, you should fertilize potted blueberries about every two weeks during the growing season and must not forget this: A lack of nutrients leads to a rather meager harvest.

frequently asked Questions

Do blueberries absolutely need a special fertilizer?

For blueberries you can use a normal berry fertilizer (€3.94), which has a slightly higher nitrogen content. These fertilizers are optimally tailored to the needs of berry bushes, which ultimately include blueberries. Alternatively, you can also use horn shavings or a special blueberry fertilizer. Although this is not absolutely necessary, it makes sense if you have to supply many blueberry bushes with it.

Can I also fertilize my blueberries with rhododendron fertilizer?

Rhododendrons, azaleas and blueberries are among the plants that need acidic soil to thrive. They also have very similar demands on their nutrient supply, which is why you can easily supply blueberries with rhododendron fertilizer. Incidentally, currants, cranberries and cranberries also need the same location and care, which is why these species are good plant neighbors.

Which home remedies are suitable for fertilizing blueberries?

Coffee grounds are very suitable for fertilizing blueberries, as they contain many valuable minerals and trace elements. Coffee grounds also acidify the soil, which blueberries are known to love. However, coffee grounds alone are not sufficient as fertilizer, which is why you should always add horn shavings and coniferous compost - or even blueberry fertilizer. Never use fresh coffee grounds, only dry them - otherwise they can become mouldy.

Can I fertilize blueberries with compost?

Blueberries and other ericaceous plants should never be fertilized with compost or stable manure, as these have too high a pH value. It is therefore better to omit these species from the annual compost distribution or to use special, acidic coniferous compost.

What else should you consider when caring for blueberries?

In addition to nitrogen-rich fertilization in spring and further adjusted fertilization over the course of the year, it is important to water blueberries regularly and regularly. The bushes should not stand on dry soil, as they will only develop a few small berries. Mulching the soil is also important, if possible with pine litter or pine mulch.

How much does blueberry fertilizer cost?

Compared to other types of fertilizer, special blueberry fertilizer is quite expensive. For one liter of liquid concentrate or three kilograms of solid fertilizer you have to budget between approx. 15 and 20 euros. Rhododendron fertilizer is also similarly expensive. On the other hand, berry fertilizers and natural fertilizers such as horn shavings are much cheaper. However, when using blueberry fertilizer, you ensure that the shrubs are optimally supplied.

horn shavings

our recommendation
Dehner organic horn shavings with long-term effect, for balcony and garden plants, 2.5 kg, for approx. 25 sqm
8.49 EUR To the product

Blueberries have a high nitrogen requirement, which is why you should supply the shrubs with a nitrogen-rich fertilizer when planting and once a year at the beginning of spring. Horn shavings or horn meal are very suitable for this. This is a natural fertilizer that is naturally rich in nitrogen.

Moorbed soil / soil for blueberries

our recommendation
Jasker's Earth for Blueberries | Potting soil for berries | for healthy and tasty fruits | (blueberry earth, 20 L)
16.99 EUR To the product

As typical forest dwellers, blueberries prefer a shady location and acidic potting soil. Humus-rich garden soil with a neutral to alkaline pH value is not suitable for the popular berry bushes, which is why you should put them in bog bed soil or rhododendron soil. Special potting soil for blueberries also creates optimal growth conditions and thus a rich harvest.
