Even if hornbeams are very robust, they are happy about fertilization from time to time. We show what you should consider when fertilizing hornbeam hedges.

hornbeams (Carpinus betulus) have trunks and leaves like beeches and also look like them – almost. Because hornbeams are actually not beeches at all. They belong to the birch family (Betulaceae) and because of their similarity are only erroneously referred to as beeches (Fagus) designated. As native plants, hornbeams are optimally adapted to our Central European climate. This simplifies maintenance immensely. In nature, the trees prefer particularly nutrient-rich soils. A good prerequisite for a healthy hornbeam hedge is deep garden soil. If you do not have these, you should enrich the soil with mature compost or a primarily organic long-term fertilizer before planting.

Fertilizing a hornbeam hedge: the right time

Hornbeams actually only need fertilizer when they are young, or when they show symptoms of deficiency and growth disorders. Initial fertilization before planting is highly recommended. In principle, however, fertilization should only be carried out in spring, shortly after new growth. Fertilizing later in the year can result in frost damage the following winter.

What should you fertilize hornbeam hedges with?

Hornbeams are considered to be extremely robust. The fertilization is accordingly rather economical. As a rule, it is sufficient to fertilize only younger plants. With older copies this is usually superfluous. With their heart-shaped root system, the plants can penetrate deep into the soil and collect nutrients. A wide variety of local people will help you with this mycorrhizal fungiwith which they live in symbiosis.

The best fertilizer for hornbeam hedges are their own leaves. They have very easily decomposable leaves, which turn into excellent hummus. So just leave the leaves under the plants for the sake of the hedge. As a result, you get good humus with valuable nutrients, improved soil fertility and comfortable conditions for mycorrhizal fungi. If the soil is not very good or your plants show signs of deficiency such as sallow leaves, you can supplement with various mainly organic fertilizers.

Fertilize hornbeam hedges primarily organically: application recommendation

Organic fertilizers not only bring nutrients to the soil, but also promote soil fertility and soil activity. However, you don't have to overdo it. It is enough if you add a portion of ready-made compost or organic fertilizer with long-term organic effects like ours in the spring Plantura organic universal fertilizer administer.

Fertilize hornbeam hedges with minerals

Mineral fertilization is not recommended for hornbeams. The plants are among the less demanding plants that can get along with little. Too much fertilizer causes more damage than a lack. Therefore, to be on the safe side, use primarily organic fertilizers to avoid over-fertilization. Mineral fertilizers are available to plants more quickly, making over-fertilization more likely. If you still want to use a mineral fertilizer, then you should opt for a depot fertilizer.

Fertilize hornbeam hedges with home remedies

Fertilizing hedges with home remedies is rather time-consuming, since home remedies are usually used on a smaller scale. So stick to organic materials like compost or manure in smaller amounts. But the best fertilizer is the plants' own leaves. It contains what is needed for the formation of new leaves.
