Brief description of the genus
Hydrangea - flowering plant related to the family Hortensia, genus consists of approximately 70-80 species.The greatest variety of species grows in East Asia.
Features of the autumn planting
All species of this genus are frost-resistant and shade-tolerant, only they do not tolerate direct sunlight. The site should be slightly shaded, and solar lighting is desirable only in the morning. When choosing a place to plant, it is worth considering that the flowering is fully enjoyable and the plant can fully grow.
Type of soil for growing
The soil in which the plant will be planted should be: loose, moderate humidity and good permeability of water and air. Of great importance is the acidity of the soil, because hydrangea prefers an acidic environment, and in neutral or alkaline, it will suffer from iron deficiency.
The timing of planting plays a big role in the successful cultivation of a crop. In areas with warm climatic conditions, hydrangea is planted in the first half of autumn. It is best to plant in September, so that the plant had time to get stronger and take root before the frost. For starters, it is best to purchase 4-5-year-old seedlings for planting, they are strong and quickly take root.
Having determined the place for disembarkation, you need to prepare a landing pit. Planting hydrangeas in the fall in open ground is made in a hole, a depth of half a meter and a diameter of 40-50 centimeters.If the soil is poor, then it is better to make the pit deeper. When planting a hedge observe the distance between the bushes up to 1.5 meters. The pit should be almost to the top filled with soil mixture (leaf soil, humus, sand and peat in the ratio 2: 2: 1: 1). For 10 kg of humus add 60 g of superphosphate and 20 g of sulfuric potassium and urea.
How to care for hydrangea in the fall
Caring for hydrangea garden in the fall is the same as in the spring and summer periods. The plant needs soil loosening, watering, pruning and protection from pests.Although the bloom is already passing, but fertilizing must be carried out necessarily, because the shrub must gain strength before wintering.
The plant is moisture-loving, therefore, requires a regime of watering. In the dry season, water 2 times a week, and in the rainy one once a week. The main thing - to prevent stagnant moisture, so as not to harm the root system. The plant should be watered with settled water. Under an adult shrub an average of 40-50 liters of water is poured at a time. As a preventive measure, vinegar or citric acid is sometimes added to the water for irrigation.
In early September, the last fertilizing of the hydrangea for the current year takes place. The composition of autumn fertilizers includes a phosphorus-potassium complex. Nitrogen supplements in this period are not needed.
Autumn treatment for diseases and pests
Autumn processing is more preventive than curative and is carried out with the aim of eliminating diseases and pests that could settle in the soil or bark for wintering. A popular and effective drug is Abiga-Pic or 1% Bordeaux liquid. Such events are held after leaf fall.
Time for cutting hydrangea for specialists is a controversial issue, some advise it to be held only in the spring before bud break, while others advise, on the contrary, it is advised in the fall. The advantage of the autumn pruning is that the vital activity of the plant subsides and there is no risk that it will expire with juice. Depending on the type of hydrangea, this event is divided into two types:
- The first group includes: representatives of large-leaved hydrangea, serrated, barbed, lianovid, oak-leaved, petiolate, Sargenty. Their pruning is sanitary and cosmetic value. Remove dry, broken and diseased branches, as well as old inflorescences. This type of processing is due to the fact that in these representatives the flowers are formed on old shoots that were formed earlier;
- The second type is hydrangea, in which the flowering appears on the young shoots of this year. Therefore, autumn pruning of paniculate and tree hydrangea is required. Tree hydrangea is pruned from the age of four. Pruning hydrangea pruning is carried out like a tree, only old and diseased shoots that grow from one point are cut off.
How to transplant hydrangea in autumn
Large-leaved varieties in the fall are not advised to replant, they are difficult to adapt. Trees and paniculate hydrangea species transplant well in the autumn.
When to replant a plant
For transplanting hydrangea in the fall, the plant must be prepared from the spring. To do this, at a depth and width of up to 30 cm, dig a trench around the perimeter of the tree trunk and fill it with compost. With regular watering, the plant will put the newly formed roots directly into the compost. Transplantation is carried out in the same time as the landing, and this is the beginning of autumn.
So that you do not interfere with the branches of the plant, they should be tied with twine or rope. Hydrangea should dig around on the outer edge, try not to damage the young roots. Then transfer to a new landing site (the landing pit must be prepared in advance). Preparation of the pit and care of the plant in the autumn period are described above. To get the plant settled better and faster, spend rejuvenating pruning. If you conduct a transplant with the aim of growing a hedge, then make sure that the distance between the bushes was at least one meter, and preferably 1.5 m.
Main breeding methods
The main and most accessible breeding methods for each gardener are: dividing a bush, cuttings and breeding root shoots.
This method is convenient to use when transplanting bushes. Thus multiply almost all types of hydrangeas, except paniculate. Dig a plant and remove it from the ground so that each separated bush has healthy shoots and roots. During this manipulation should be very careful not to damage the rhizomes. In case of minor damage to the indigenous areas, it is worth smearing them with crushed coal, and then land them in prepared pits.
Most often produced in spring or summer from lateral annual shoots, but there is also winter grafting, which they begin to carry out already in mid-autumn. In October, dig up a hydrangea bush, transplant it into a pot and transfer it to the basement. Preparation of a mixture of land is the same as when landing in open ground. In January, the pot needs to be moved to a cool, lighted place, after a few weeks at 10 ° C the cuttings begin to grow.In February, it is necessary to cut green cuttings with 2 internodes from the mother plant. Above the leaves above and below them leave 1 cm.
In order not to be confused and not to plant the stalk upside down, make the lower cut straight and the upper slant. Bottom leaves must be removed completely, and the upper cut in half. Process the upper cut Zelenko, and the lower soak in the growth stimulator. For the prevention of root rot in a pot to a depth of one centimeter, place the Glyocladin tablet. Cut the cuttings to the top leaves in a pot of nutrient soil. Such cuttings grow quickly and form a good root system. In the spring they need gradual acclimatization, and then they can be planted.
Reproduction root shoots
Propagating the bush overgrown, you need to be very careful and attentive. It is necessary to carefully remove the top layer of soil and separate shoots shoots so as not to harm the roots of the uterine bush. After that, the shoots are planted for rearing (1-2 years), and then it is necessary to make their landing on a permanent place.
Preparing for the winter
Even winter-hardy types of hydrangea at a young age. badly tolerate hard frosts and need shelter. Hydrangea requires high-quality care in the fall and preparation for the winter period already from September. All leaves except the uppermost leaves are removed from the bush, which accelerates the ripening and growth of young shoots. Then feed the plant with fertilizers consisting of phosphorus and potassium.
In regions with warm climatic conditions, the hilling of a bush will be sufficient, and in areas with low precipitation, but with severe frosts, it will be necessary to organize the shelter of the plant. Bushes of small sizes are usually covered with peat and wrapped with foil. High bushes can be tied with a rope and laid neatly, so as not to damage, on the boards, laid out beforehand on the ground. In order for the boards to not move from the spot, nail them with long nails to the ground. Pour the shrub covered with sawdust or spruce, and cover the top with lutrasil or spanbond.
For areas with temperatures down to -40 ° C such shelter options: pristvolny circle you need to warm lapniknik, branches from the center to the side pull to the ground and secure them with braces, throw the center of the bush with peat, and branches with spruce branches. Put a lutrasil on top of a spruce branch and squeeze it on the sides with stones so that it will not be blown off in a strong wind. This shelter is labor-intensive, but is of very high quality.
It is impossible to bend a lignified hydrangea without damage, so it should be wrapped with lutrasil and fixed with scotch tape or twine. Place a metal grid around the plant, which should be 15 cm above the bush. Between the grid and the bush, scribble dry foliage and wrap this construction with roofing paper or foil. Winter hardiness of hydrangea increases with age and after a few years it may not need shelter at all.
Hortensia is a beautiful flower that pleases with its bloom for a long period. The plant charms not only with gorgeous buds, but also with unusual bark and originality of foliage. If you decide to plant a bush in the fall, then in spring you can expect flowering. Hydrangea in the fall needs care and preparation for long frosts, because its development depends on the quality of the autumn events, growth and bloom next year.
