With errors in care and the wrong choice of a place for growing roses, flowering and bud formation problems often arise, which is why it is very important to follow the correct agricultural practices when cultivating this popular ornamental plant at all stages of vegetation.
There are several reasons that negatively affect the absence of rose buds, but almost all of them are associated with the lack of competent care for decorative culture:
Quite often, the absence of buds is the result of improper preparation of the rose bush for winter cold, which provokes the formation of only green mass next year. Also, it will not be possible to achieve flowering if the place of grafting when planting a rose is left on the surface. In that case, the formation of buds on the dogrose or the complete absence of flowering is often observed.
However, the main cause of lack of flowering problems is most often due to incorrect pruning. The pruning rules are as follows:
Important to remember, that one of the main ways to stimulate the formation of buds is the timely removal of all faded flowers.
The most common cause of normal formation and subsequent non-opening of buds is the cultivation of rose bushes in the shade, as a result of which the decorative culture lacks sunlight and the flowering process is greatly inhibited. In this case, during a visual inspection, all buds have absolutely normal development, and the flower does not bloom, and petals become brown. It is also very difficult to open the buds of large-flowered and fine-petal varieties of roses with prolonged wet and cloudy weather.
If the rose bushes receive a sufficient amount of sunlight and are provided with the right care measures, but the buds fade or fall, then you should check the aerial part of the decorative culture for tiny, bright green, quickly moving insect pests - leaflet.
The vital activity of this plant parasite negatively affects not only the buds, but also the young foliage, which is covered with small brownish-cotton spots and is deformed. As a rule, the treatment of garden roses and soil in trunk circles with the drug Fenitrotion allows you to get rid of such a problem as soon as possible. The buds of a rose also fall off when a decorative culture is damaged by some pathogens.
Currently, it is possible to independently identify and begin the most effective treatment of several damaging factors that provoke lack of flowering or defective blooming garden roses:
Thus, in addition to diseases and pests, the main adverse factors causing problems with budding and flowering of garden roses are poor weather conditions, increased humidity or dryness for a long time, inadequate lighting and ventilation of flower beds, and mechanical damage to peduncles.
Most diseases of rose bushes are quite difficult to treat, therefore, it is most advisable to correctly and timely carry out all preventive measures, aimed at reducing the damage to rose bushes by diseases and damage by plant parasites:
Also, in addition to the prevention of diseases and pests, it is very important to ensure that the decorative culture has proper placement on the site and competent care at all stages of the growing season, including the implementation of activities such as watering, top dressing, timely pruning and bush formation, as well as weeding and loosening of soil in near-stem circles .
