Lack of nutrients can be the reason why the hydrangea does not grow
The hydrangea is not growing - what could be the reason?
The Hydrangea is one of the robust garden plants that require little care and yet flourish and thrive well. If the hydrangea does not grow or hardly flowers, care is usually the cause. We explain what you need to look out for.
The right substrate
In normal garden soil, the hydrangea does not thrive very well. Place the flowering plant in rhododendron soil, which has the optimal structure for hydrangea. This soil keeps the moisture well, but does not tend to wet by compaction.
Moderately but regularly fertilize
The Hydrangea is one of the plants that have very special requirements for nutrient supply. Hydrangea needs plenty of nitrogen and potassium to flower well. The fertilizer should also contain sufficient minerals such as iron, sulfur, manganese and zinc. The phosphorus content of the fertilizer must not be too high at the same time.
Therefore, many common plant fertilizers are completely unsuitable. Preferably use hydrangea fertilizer, which is available from well-stocked garden retailers. Alternatively, you can fertilize the hydrangea with azalea or rhododendron fertilizer.
Overgrown perennials
Hydrangeas are often on the market with abundant Blütenflor in the trade. When the umbels bloom, sometimes the hydrangea does not produce new flowers and hardly grows in the first year. Fertilize the Hydrangea regularly as indicated on the fertilizer's packaging, it has gathered enough force at the latest in the second year and drives out vigorously.
Lack of winter protection
Although the hydrangea is relatively winter hardy, the plant takes damage in very cold and harsh winters. In one year with low minus temperatures, the leaves often form much later and the flower buds formed in the previous year could be frozen.
Therefore, ensure sufficient winter protection already in autumn:
Tips & Tricks
Hydrangeas that do not grow well were often planted late in the year. The hydrangea should have spent some time in the ground before the first frosts, so you have enough roots formed and well grown.
