Hydrangea

The name of the hydrangea comes from the name of its discoverer, the French lady Hortense Barré Lepante around the nineteenth century. The name of the plants of the genus Hydrangea of ​​the Sassifragaceae family and in particular hydrangea hortensia, native to China and Japan. Hydrangea is a plant grown almost exclusively for ornamental reasons. This plant is a shrub about one to two meters tall. The tending hydrangea looks like a very branchy shrub, with very broad and opposite leaves, oval-acute and serrated. As regards the flowers, they appear as large globose corymbs in which there are two types of flowers. The flowers that bloom in hydrangea are sterile and fertile. The two flowers are extremely distinctive. The fertile ones are, in fact, positioned in the center and are small in size and light colors and positioned in the center. The sterile ones, on the other hand, are decidedly brighter colors, decidedly larger, if compared to the fertile ones, and positioned at the edges. The sterile flowers have an exquisitely function as a banner or are used to attract insects. The sterile flowers of hydrangea can be pink, blue, or white. Hydrangea through its flowers can be a kind of thermometer for the soil. In fact, if there is a significant presence of iron salts in the earth, the pink flowers tend to change color and become bluish blue.


The climate and exposure

Basically hydrangea is a perennial shrub that lives at two speeds throughout the year. In fact, during the cold seasons, for example in winter, this plant tends to strip completely while it returns, so to speak, to life with the approach of the warm seasons, around March the new leaves begin to appear around March, and flourish again in spring. and in summer. Basically, hydrangea lives very well in open ground. If you decide to let the plant live in pots, you have to keep in mind some tips to keep the plant in good health and flowering as much as possible. To begin with, it must be borne in mind that hydrangea loves the sun but it is very important not to expose the plant to direct sunlight. The ambient temperature should never exceed eighteen degrees.


The terrain

As a rule, as regards the soil, the hydrangea does not give big headaches. As mentioned before, the hydrangea and specifically its flowers are a sort of thermometer of the balance of the soil in which they are planted. In fact, the colors of the hydrangea flowers are not random but directly depend on the morphological characteristics of the surrounding area. In fact, if the soil is acidic, the hydrangea will give its flowers a pink color while if the soil is alkaline the flowers will come out of a blue and bluish-blue color.


The watering

The watering of the hydrangea must be abundant in the period in which this plant returns to cover itself with its leaves and adorn itself with its splendid flowers. So during the period from spring to all summer you need to be very generous with watering in order to keep the substrate always sufficiently moist. We must be careful not to overdo it so as not to give rise to molds and fungi of various types. It is also advisable to spray the upper part of the plant with fairly pure water, better if the rain one.


Fertilization

For what concerns the fertilization it must be carried out during the spring and in the summer period on a weekly basis. The method of administration is liquid by adding liquid fertilizer to the irrigation water and thus watering the hydrangea.

The plants planted in the garden must be pruned towards the end of winter in areas with a harsh climate. In this way all the elements that will be pruned, therefore the branches and dried flowers

protect the new delicate branches. In hot climates, pruning can be done immediately in order to immediately release the buds from which the flowers will spring.

For hydrangeas living in apartments, pruning will be done immediately after flowering, in early autumn.


The multiplication

The multiplication occurs almost exclusively by cuttings.

The whole operation must take place at the end of flowering.

First of all it is necessary to take some branches placed at the top of the plant, preferably those on which flowers had grown, with a maximum length of about fifteen centimeters. After doing this cut the lower leaves. Then place the cuttings in a mixture of fertilizer and sand.


Hydrangea: The planting

Planting does not involve any problems. The main thing is to create an optimal environment for the plant to take root safely in the new environment.

In the hole where the plant will be inserted, it will be necessary to add organic fertilizer in order to help the plant to root.

How to adjust the color of hydrangeas

First of all, if you want to adjust the color of your hydrangeas you have to act on the ground: as we have mentioned, in fact, its acidity and therefore its ph influence the shades of the flowers. Be careful, however, because only two varieties have this characteristic: macrophylla hydrangea and serrata hydrangea. If the soil is acidic and has a ph lower than 6 your hydrangeas will be blue, while if, on the contrary, the ph is basic (higher than 6) the flowers will be pink. Now you are wondering what to do to change the color of your hydrangeas and you will be happy to know that it is quite simple.

If you grow plants in pots, just use a soil of the desired ph, while in full earth it could be a bit more complicated but still not impossible. To make the soil more acidic you can for example use the coffee grounds, but just go to any nursery to find specific products to regulate the ph of the earth.


A small branch is enough

You will need to choose a hydrangea branch devoid of flowers but quite rich in leaves. Cut the branch to obtain about 15 centimeters in length, leaving only the first 2 or 3 leaves. All the others will be eliminated. Once you have filled a pot with potting soil and a thin layer of expanded clay at the base, drill a hole in the ground. Then, insert the freshly peeled twig. In the next month, care must be taken to keep the soil moisture constant, periodically vaporizing water. The hydrangea cutting needs a place that is not too cold or exposed to direct sunlight.
