Hedges need nutrients
Hedges form extensive roots in order to draw as many nutrients as possible from the soil. The addition of fertilizer supports the growth of young plants.

The salts contained therein remove fluid from the roots, so that the plants dry out and die.

These nutrients are important
The shrubs need carbon dioxide to develop glucose during photosynthesis. Nitrogen is important in the formation of proteins. The plants use this nutrient to produce chlorophyll. Phosphorus is essential for healthy plant growth. As a structural element, it ensures energy transfer together with other substances.
Potassium protects the organism from external influences. It makes the plant resilient and reduces disease. In addition to these nutrients, the roots need oxygen and a number of trace elements. With the water, the nutrients are transported in the pathways of the plants and brought to the respective places.
Time for fertilizing
Fertilize your hedges during the growing season between March and August when the plant needs nutrients to grow. The ideal time is when the plants sprout. You should refrain from fertilizing in autumn. The late availability of nutrients causes the hedge to sprout again. The wood does not mature completely. It stays soft and is therefore prone to frost.
Organic fertilizer
Compost is suitable as an organic fertilizer, Horn meal or Horn shavings(€ 32.93 at Amazon *) and organic Complete fertilizer from the trade. Compost improves the soil as it has a positive effect on the air and water balance and on its structure. Not every plant can tolerate compost fertilization, as this slightly increases the pH of the soil. You shouldn't fertilize rhododendrons with compost.
Horn meal and horn shavings are of animal origin. Horn meal is finer than horn shavings and develops its effect faster. This fertilization mainly supplies the hedges with nitrogen and phosphate. Since the products only decompose slowly in the soil, a long-term supply of nutrients is guaranteed. Fertilize your hedges in autumn so that the substances in the soil can dissolve.
Organic complete fertilizers have these advantages:
- long-term and sustainable effect
- tailored to individual needs of different types
- ideal combination of organic substances
Mineral fertilizers
Blue corn is a mineral fertilizer that is rich in nitrate, phosphate and potassium. While original compositions were not very environmentally friendly, new formulations are characterized by a lower impact on the environment. Magnesium sulfate is also known under the term Epsom salt. It is suitable as a root fertilizer and, if there are deficiencies in the leaves, also as a foliar fertilizer. Potassium fertilizer are mainly used for ornamental trees. Evergreen plants benefit from potash fertilization before winter, which acts as a natural frost protection.
