Care hydrangeas


Hydrangea care


The hydrangea is a plant of Asian origin, which is chosen for its long-lasting flowering and for the beauty of its flowers. Depending on the species and the ph of the soil used during cultivation, it is possible to have white, lavender or pink flowers. This type of plant does not require particularly complex treatments, so it is also chosen by the less experienced. For a correct care of the hydrangeas, a constant and abundant watering must be provided, particularly in summer when the plant reaches its maximum flowering and the outside temperature is high. The soil should be changed a couple of times a year, especially in autumn, when the specimen begins its vegetative cycle. The earth is good to be slightly acidic, spreading mature manure. A good cure for hydrangeas is the pine bark added to the bottom of the pot. This keeps the soil always fresh and helps the acidification of the earth with its natural decomposition. Hydrangeas do not fear diseases, but are often attacked by parasites such as cochineal. The treatments in this case concern insecticides that can be purchased in specialized shops.

Pruning hydrangeas



To have care of hydrangeas it means performing the right pruning, which allows the correct development of the plant. This is done once a year, in March, when the plant is in full growth. During the winter some inflorescences are left to protect the gems, but in March they can be eliminated having finished their task. The dry and older branches must also be removed, recognizable by the cracks in the bark. If the winter was particularly harsh, and the branches at the base of the plant suffered frost, they are pruned to allow for summer flowering. In fact, hydrangeas do not die in winter, thanks to their ability to withstand even the lowest temperatures. In the case of shrubby hydrangeas, even less demanding, pruning should be done in spring instead of in autumn, and the watering can be more rare given that they also endure periods of drought well. With a lighter pruning, there will be more and larger flowers. The quercifolia hydrangea needs only a pruning in spring while the climbing hydrangea is not pruned except to eliminate the dry parts.

Grow hydrangeas



Hydrangeas require two main things for their cultivation: acid soil and abundant watering. Whether grown in pots or in the garden, exposure to sunlight is unimportant as hydrangeas grow well even in shady environments. They are plants that resist cold temperatures and this allows their cultivation both in mountain areas and in more temperate climates. Naturally their flowering takes place in summer when the milder climate allows the opening of the buds. For their correct growth, water stagnation must be avoided. This is why the soil must be slightly sandy, so that there is a drainage element that avoids water deposits. Furthermore the soil must be fertilized at least twice a year to maintain a certain acidity. If grown in pots, better with holes at the base, it is good to add gravel or clay to its bottom, so that the water flows properly. Once the first seedlings are ticked, they should be watered abundantly and regularly, especially in summer, when the flowering takes place, and the soil is completely dry.

Care hydrangeas: Variety of hydrangeas



There are many varieties of hydrangeas that can be planted. The hydrangea macrophylla is the most common hydrangea, which must be grown both in pots and in the garden. Its flowers vary from pink to blue depending on the acidity of the soil. It is possible in fact to change the color of the flowers by changing their pH during the autumn, when the plant begins a new vegetative cycle. The hydrangea macrophylla normalis has flowers of a more open shape. It is mainly suitable for woodland environments, therefore it is suitable for garden cultivation. Also here the flowers vary from pink to blue. Hydrangea quercifoglia instead, is so called because the leaves resemble the bark of an oak. This particular variety can be grown in pots or in the garden and prefers sandy soils. Its flowers are white, while the leaves take on a particular shade of red-orange in autumn. Hydrangea arborescens instead it is preferable to make it grow in the garden due to its size, supporting it with sticks to help its development. Finally the hydrangea panicula is the only variety of hydrangea that can be grown in the form of a small tree with white flowers.
