Fertilising before winter dormancy

Your plants have bloomed the whole summer and thus consumed a lot of nutrients. Now it is time to fertilise your plants for the last time before the rest period as they do not absorb nutrients during this time.

Fertilisation is generally only carried out during the growth period, i.e. from February to approximately mid-August. If fertilisation is carried out for longer, the wood cannot mature by winter. The plants then sometimes form new, thin shoots, which are very sensitive. Therefore, never fertilise directly on the dry root bale.

Those looking for a suitable fertiliser can choose between mineral and organic fertilisers. In the case of mineral fertilisers, one often comes across the term complete NPK fertiliser. This stands for nitrogen (N), phosphorous (P) and potassium (K). Nitrogen is required by the plants for growth. Phosphorous strengthens the roots and ensures magnificent blossoms, leaves and fruit set. Without potassium, the supply of water to the plant is destroyed. With such complete fertilisers, deficiencies are reliably and quickly prevented.

Organic fertilisers are also long-term fertilisers. The most well-known organic fertilisers include compost and horn shavings or horn meal. Compost, for example, is suitable for supplying nutrients to many trees and shrubs. Semi-mature compost is particularly rich in nitrogen. It should only be applied on the surface, as it may otherwise damage the roots of the plants. Mature compost contains only few nutrients but improves the soil structure.
