When do hydrangeas bloom?

The hydrangea bears the botanical name Hydrangea and, depending on the variety, grows either upright or as a climbing plant. As a deciduous flowering shrub, the plant transforms every garden into a romantic sea of ​​flowers during its flowering period. Since the hydrangea also grows under shady site conditions, dark corners of the garden can also be beautifully designed. The beginning and duration of the flowering period also depend on the variety.

beginning of flowering

If hydrangeas feel comfortable in their location, then the first flowers appear very early. Some varieties flower as early as spring, while others only start flowering in summer. In addition, the beginning of the flowering period depends on care and site conditions. The condition of the soil, the weather, the incidence of light and the fertilizer also play an important role in flowering. If these factors are not optimal for the hydrangea, then it can happen that the flowering period is delayed. In addition, the pruning of the hydrangea in the previous year must not be too severe. Since the plant is already preparing its flower buds for the next year after flowering, they must remain on the bush. Therefore, only the completely dried inflorescences and branches should be cut out.

duration of the flowering period

Hydrangeas bloom long and abundantly, so the shrubs transform the garden into a colorful floral paradise. Just like the beginning of the flowering period, the end depends on many aspects. The better the site conditions and care, the longer the flowering period. In order for hydrangeas to thrive and bloom for a long time, it is important to ensure that there is always an adequate water supply. If the hydrangea is already dropping its leaves and flowers at midday on hot summer days, the plants urgently need additional watering units. Otherwise, flowering may come to an end prematurely. In addition, hydrangeas are heavy feeders and have a high nutrient requirement. Therefore, the plant is dependent on frequent and plentiful fertilizers in order to develop its beautiful flowers for a long time.

• All varieties bloom throughout the summer
• Many varieties bloom into autumn
• In general, the flowering period for hydrangeas lasts until September
• Late-flowering varieties even flower until October
• Exotic varieties usually only flower in the summer months
• Optimal care promotes flowering

• Use special hydrangea fertilizer
• Alternatively, fertilizers for rhododendrons are possible
• Only fertilize hydrangeas until the end of July

inflorescences

Hydrangeas are available in a wide range of flower colors in specialist shops. It can also happen that the flowers change color. A change in the pH value in the soil, which can occur depending on the year, is often responsible for this. Brightly flowering hydrangea varieties first form green buds and then take on the actual color of the flowers. When they fade, the inflorescences turn green again. Darker flowers, on the other hand, often turn brown-red when they fade. New breeds and hybrids surprise with unusual flower colors, some of which fade to a red hue in autumn. Flowering hydrangeas are already on sale in early spring, these specimens are propelled into greenhouses. Since the hydrangea is sensitive to frost, early planting outdoors does not do well for the plant. For this reason, hydrangeas in full bloom at the beginning of spring are better kept in the conservatory.
