Potted hydrangea

Potted hydrangea care

To take care of a beautiful specimen of potted hydrangea, you must strictly follow some instructions. First of all, the plant should be watered very often, especially in summer and even more so if you live in an area with a particularly hot climate in the summer months. It will also be necessary to regulate with the rains: if from June onwards it never rains, then the hydrangea will need several liters of water a day; if it rains, the doses must be reduced. Water stagnations, however, are to be absolutely avoided, just as sunny locations are to be avoided. The hydrangea must be in a semi-shaded place, otherwise the direct rays of the sun could cause its leaves to dry out in a short time. However, especially during the flowering period, it would be advisable for the plant to receive some sun:

The cultivation of a potted hydrangea must be based on a fundamental factor: this species is acidophilic, therefore it will need a particular soil. Acidophilic plants prefer acidic soils, but hydrangea actually adapts to other types of soil as well. However, the ph level of the substrate determines the color of the flowers: generally, with a ph 4.5 or 5 you will have the proverbial blue flowers, while with a ph of 6 or 6.5 you will get other colors, such as pink or red. Growing it in pots, it is possible to determine the color of the flowers of our hydrangea very easily, just compose a more or less acid substrate and that’s it. Much will also depend on the water we use for irrigation, because if it is calcareous the acidity level will drop. If, on the other hand, we do not intend to administer ph products to our plant, then the conformity of the soil will naturally determine the color of the flowers. In spring it is however good to give our specimen a slow release fertilizer that can provide it with the nutrients necessary for flowering.

Potted hydrangea pruning and diseases

To keep a potted hydrangea healthy for a long time, it will need to be periodically pruned. This operation must be performed carefully and will mostly serve to give a shape to the crown, to ensure that it does not overflow from the container. Pruning must be carried out in spring and consists in eliminating the old and damaged branches, while the young ones, born in the year just passed, must not be touched at all. Older plants, on the other hand, need to be pruned much more, as this will encourage them to produce new green shoots. In general, hydrangea is a fairly hardy plant and is rarely attacked by pests. The only serious problem it could have is chlorosis, which is a decay of the plant that leads to yellowing of the leaves.

Hydrangea in vase origins and curiosities

The hydrangea that we grow in pots today is actually a plant with ancient origins. Its botanical name is Hydrangea, a term that refers to the hard capsules that contain the seeds, similar to containers in which rainwater was once collected. In Europe, the cultivation of this plant really spread only from the nineteenth century, that is when the beautiful Chinese and Japanese varieties arrived here, which in fact replaced the American ones, the only ones known until then in the old continent. In the East, as well as to adorn gardens, hydrangea is also used for other purposes: the Japanese, for example, use the stems of some varieties to produce objects such as sticks, pipes, handles and handles; with the leaves of the variety called serrata, on the other hand, a herbal tea is prepared, called celestial tea by the Orientals. The name is not a coincidence: with this infusion, in fact, the statue of Buddha was washed during some rituals.
