Hydrangeas: rich flowering balcony plants that enchant
The hydrangea is a perennial flowering plant that also thrives in the tub. With its large umbels, it gives the patio a romantic touch throughout the summer. In particular, the delightful new breeds with their colorful flowers are suitable for balcony greenery.
The right location
Hydrangeas are not sunbathers and prefer shady locations. Ideal is an east, west or even north balcony. On a south-facing balcony, you should give the hydrangea a serene location or shade the plant during the hot midday hours.
The hydrangea is very thirsty
The Greek plant name "Hydrangea" means translated "water-pulling" and stands for the great thirst of hydrangea. It feels extremely well in permanently moist soils, but at the same time it is sensitive to overgrowth. This can already prevent you from planting:
Water moderately but regularly
The hydrangea also reacts very sensitively to dryness. On hot summer days, it is recommended to water the flowering plant in the morning and in the evening as the substrate in the tub can only store a limited amount of water. Pour away excess liquid in the coaster after a quarter of an hour so the roots are not permanently in the water.
Do not forget to fertilize
In order for the hydrangea in the pot to grow new flower umbels throughout the summer, it needs regular fertilizer supplies. Preferably use hydrangea fertilizer whose nutrient composition is optimally adapted to the requirements of the plant or, alternatively, a rhododendron or azalea fertilizer.
Blue hydrangeas have special requirements
If you maintain a blue hydrangea, it is also necessary to add commercially available hydrangea blue to the irrigation water twice a year. These hydrangeas should also be watered from time to time with vinegar water, which should have a pH of about 4.0 to 4.5. This acidifies the soil in a natural way so that the plant can absorb the potassium alum in that medium. You can measure the pH of the water and the substrate yourself with test sticks, which you can get from the garden shop.
Tips & Tricks
Although hydrangeas are relatively resistant to diseases and pests, occasionally spider mites or aphids nest in the potted plants. Therefore, regularly examine the hydrangea for infestations. Detected early, the pests can be successfully controlled by natural means.
