Mulch keeps the soil around the roots of the hydrangea moist, keeps out weeds and provides the plant with nutrients
Hydrangea mulching promotes healthy growth
The hydrangea prefers acidic soils, which is why it is often recommended to incorporate deciduous or needle compost regularly into the soil. In addition, you can mulch the soil around the hydrangea to keep the soil weed-free. What further benefits regular mulching has and why only high-quality bark mulch should be used are explained below.
What is bark mulch?
Bark mulch is shredded tree bark and no further additives are added. However, there is no uniform legal regulation, so that bark mulch must not consist of one hundred percent bark. In particular, very inexpensive bark mulch by-products such as twigs, shavings and plant waste can be mixed. Since cadmium is released to the substrate during the decomposition of the material, experts now advise against the use of uncertified bark mulch.
Mild environmentally friendly
As an alternative, these materials are suitable for mulching the hydrangea:
Many of these products are used in the care of your own garden and are thus available at low cost.
How is mulched?
The higher the layer thickness, the longer the positive properties of the mulching will last. The minimum is a layer of five centimeters. We recommend that you do not save on the mulch material and apply a layer about ten centimeters thick evenly around the hydrangeas.
The effect of mulching
If the layer thickness is sufficient, the soil mulch keeps the soil around the hydrangeas free of weeds. This effect can be attributed to the substances released to the subsoil as well as the reduced air supply.
At the same time, the floor mulch provides protection against evaporation and moisture is better retained in the subsurface. The Hydrangea, which is very sensitive to drought, therefore thrives especially well. In winter, the ground mulch acts as a warming blanket and protects the hydrangea from frost.
Microorganisms and insects settle under the mulch cover and ensure a natural improvement of the soil quality.
Tips & Tricks
Compost contains a lot of nutrients. It is therefore not suitable for mulching hydrangeas. Always mix compost with other mulch materials and only dispense this valuable fertilizer.
