Hydrangea Roots - the lifeline of hydrangea
With its deep root, the hydrangea anchors firmly in the soil and absorbs not only water but also trace elements. If the roots take care of decay or are damaged too much by careless transplanting, the root system can no longer fulfill its important task.
The composition of the hydrangea root
The hydrangea is one of the flat-rooters, that is, the root of the hydrangea does not reach very far into the ground. A peculiarity of the hydrangea root is its hard Mittelstrunk, which can often be cut with propagation by division only with a saw. Around it, the hydrangea forms many fine root branches, which are responsible for the supply of the plant. When transferring the plant make sure to damage the fine root system as little as possible to ensure a good growth of the plant.
Waterlogging, the enemy of the root
If your hydrangea withers, but you water it enough, waterlogging could have damaged the roots. Root rot is caused by a fungus whose growth is promoted by too much moisture. The root system dies. Above ground, you recognize the infestation on yellow-colored, limp or dried leaves. The plant takes care and forms only weak shoots and hardly flowers.
Prevent root rot
If the deeper soil layers of your garden are heavily compressed, excess rain and irrigation water can not seep into it and accumulate. The hydrangea is permanently in the water and threatens root rot.
The remedy is provided by a drainage layer of coarse sand or gravel, which is introduced into the planting hole before the hydrangea is inserted. Since the hydrangea has very specific requirements for the substrate, you should then fill the plant hole with special hydrangea or rhododendron soil. Do not mix this substrate with sand or gravel as often recommended. It then no longer stores enough moisture, which is important for the good health of hydrangea.
Hardy roots raise climbing hydrangeas
Some hydrangeas are harbor root climbers. They form sticking roots with which they can anchor themselves on facades or trees. If you take a closer look at a branch of the climbing hydrangea, you can see that the plant only forms these roots on the side away from the light. In contact with the earth, for example, when a vine falls down and rests on the ground for a long time, the adherent roots often turn to ground roots.
Tips
Adipose roots can only be formed by young shoots. Already woody branches no longer develop any sticky roots. Therefore, it is important to support large climbing hydrangeas with a scaffold.
