Reasons why the climbing rose does not bloom and how to help the plant
Climbing roses are flowering shrubs that adorn the landscape of summer cottages and gardens. Graceful plants climb the sheer walls and fill the garden with harmony and beauty. But caring for finicky flowers is not easy. The complex of plant care includes regular pruning, feeding, spraying the bushes from pests. But even if all the rules are followed, difficulties can arise. Why aren't your favorite climbing roses blooming? Consider the reasons and ways to help the plant.
Why don't climbing roses bloom?
There are many reasons for the lack of flowering in climbing roses. Sometimes the problem can be complex. The bush does not bloom or will drop the collected buds if the planting site is poorly chosen, and there is no comprehensive plant care. When choosing a variety of fragrant beauties, attention is paid to the regions and climatic conditions in which it is recommended to grow this or that species.
Important! In the first year after planting a young seedling in a permanent place, climbing roses do not bloom.
But from the second year after planting, roses should reward gardeners with the first buds. If this does not happen, it is necessary to find out the reason for the lack of flowering.
Bad landing
The choice of a planting site for climbing roses must be taken responsibly. When planting roses, pay attention to the quality of the soil and the amount of sunlight. Partial shade is the best place for curly beauties.
If you plant roses without shading, they will fade. The lack of sunlight in the required amount stimulates climbing beauties not to pick up buds and "go" into the foliage, the stems of plants are stretched.
It is undesirable to plant roses in lowlands and in wetlands. Stagnation of moisture at the roots adversely affects flowering, fungal diseases arise, the roots quickly rot.
Climbing rose bush needs a lot of nutrients, do not plant plants too close to trees and other ornamental shrubs.
Climbing beauties need supports, which are used as sheer walls, partitions, nets, arches and other devices. They are convinced that the support will reach 1.5-2 meters in height, it is precisely this size that an adult bush of climbing roses reaches.
Wild growth
All kinds of curly beauties need sanitary and molding pruning. In climbing varieties, wild growth should be cut regularly. With excessive thickening of the bush, the flowers gradually become smaller, the number of buds sharply decreases. The rose becomes a rose hip and eventually stops blooming.
Diseases and pests of climbing roses
Bushes are susceptible to attack by insect pests, which gladly settle on the leaves and flowers of plants, feed on juices and take away the vitality of the shrubs. Usually, the gardener faces this problem in the second year after planting the plant.
The greatest harm to climbing plantings can be caused by spider mites, aphids, leaf rollers and other parasites. You can fight insects with folk remedies or carry out chemical treatments. In the spring, after the sprouts awaken, the bushes are sprayed with Bordeaux liquid. The procedure is repeated during each wave of a set of buds.
It is recommended to plant companion plants next to climbing shrubs with a pungent pungent odor that repels pests. For example, marigolds, tobacco, coriander, peppermint, basil, calendula, geranium.
Outbreaks of fungal diseases overtake roses in rainy years and in places with high humidity. Climbing roses are especially susceptible to powdery mildew and bacterial cancer. One of the signs of the onset of the disease is the fall and deformation of the buds and the complete absence of flowering.
To avoid unpleasant diseases, climbing shrubs are fed with complex mineral fertilizers. Particular attention is paid to potash feeding and humus application.
Fertilization problems
An excess of applied nitrogenous fertilizers is the likely reason for the absence of buds on the climbing beauty. When applying dressings, it is important to observe the measure. Without the necessary amount of nitrogen, the plant turns yellow and throws off the foliage, and with its excess, the bush begins to "fatten", forms many young shoots and foliage, but does not pick up buds.
It is recommended to feed roses with mullein no more than 1-2 times per season. From mineral fertilizers, superphosphate or nitrate is used.
The plants overwintered badly
Often varieties of climbing beauties freeze out during severe frosts in winter. Shoots and root system suffer.
In the spring, the bush gives weak buds and is sick in the first half of summer, does not bloom.
Preparing a plant for winter frosts consists of a set of measures:
- Prune young shoots according to the recommendations for the variety.
- Spud the bush.
- Close the rhizome with humus and last year's foliage.
- Long shoots can be dug into the ground.
- Cover the plants with spruce branches, sawdust or agrofibre.
Even winter-hardy varieties may not withstand prolonged frosts in our country. In the spring, dried branches that have not survived the winter are cut out, and dead bushes are dug up.
Unsuitable variety
When buying young seedlings, make sure that the variety is zoned for growing in your area. For areas with a temperate continental climate, it is recommended to give preference to winter-hardy varieties of climbing beauties.
In the area of the Moscow region, the Urals, the Volga region, the Leningrad region, it is recommended to grow:
- Golden Gate;
- Super Excelsa;
- Snow Goose;
- Santana;
In addition, they pay attention to the recommendations of breeders on the amount of required sunny color and the composition of the soil for the selected variety.
Incorrect cropping
The bushes of climbing beauties need systemic care and regular pruning. In order for the bush to receive sunlight evenly, the branches thickening the middle of the bush are removed. But it is necessary to cut off last year's shoots with caution, without cutting off parts of the cuttings where there are buds.
Rules for pruning climbing bushes of climbing roses:
- Be sure to find out how to cut exactly the variety that the gardener planted on the site.
- Thick woody shoots are cut with a hacksaw or a sharp secateurs are used.
- Shoots are cut at an angle.
- To stimulate flowering, spring anti-aging pruning is carried out.
After pruning, the shrubs are fed and loosened.Slices with a large diameter are recommended to be treated with disinfectants or covered with garden varnish or clay.
Aging
The lifespan of a climbing rose bush is on average 7 years, from the 5th year of life the number of buds begins to decline sharply. But there are long-lived varieties. The old bush is dug up, divided, if possible.
Most often, climbing roses are propagated by cuttings. Therefore, in order to preserve the variety you like, cuttings from your favorite plant are made and harvested.
How to help the plant?
To help the rose bloom, determine the cause that influenced the decrease in flowering. Do not forget that thorny beauties are demanding on the fertility of the soil, the presence of sunlight.
Rejuvenating pruning stimulates shrubs to grow buds, even if the plantings are old. In the spring, during the budding period, the bushes are necessarily sprayed with insecticides and fungicides. They do not start the plants, young shoots thickening the bush are removed in time.
The modern floriculture industry offers an extensive selection of complex, balanced rose dressings and growth and flowering stimulants.
Preventive actions
Any problem is easier to prevent than to get negative consequences. The garden will be filled with the fragrance of climbing roses if the following rules are followed:
- Spring anti-aging pruning.
- Preventive spraying of bushes with fungicides.
- Compliance with the intervals between the bushes when planting.
- Competent agricultural technology.
- The rose variety must be adapted to the growing region.
- Do not plant roses in the shade of other plants and buildings.
- Stagnation of moisture at the roots of the plant is unacceptable; drainage from expanded clay is installed at the bottom of the planting pit.
- Shrubs are covered with additional devices for the winter, even if the variety is winter-hardy.
- Provide the plant with rational watering and complex fertilizing.
With systematic care of a flower, a correctly chosen planting site, adherence to agricultural technology, the garden will be filled with the fragrance of fragrant beauties. Climbing roses are a noble decoration of a summer cottage.
