Good afternoon, my reader. Climbing roses are a great choice for those looking for vertical landscaping. Their long shoots easily stretch upwards along the supports and bloom at a height, pleasing the eye from afar. However, it happens that sometimes these plants suddenly show stubbornness and refuse to bloom. What's the matter? Typically, one of seven factors is to blame. Let's take a look at them all.

1. Incorrectly selected soil
Climbing roses, like other types of these flowers, like the soil to be loose, well aerated, but also rich in nutrients. If they refuse to bloom, they are most likely lacking nutrition. To remedy the situation, you need to apply fertilizers as follows:
- In the first year of planting, fertilizers are not needed. However, you can add a little organic matter in the form of an infusion of mullein or bird droppings - no more than 3-5 liters under the root of the bush.
- In the spring, when the rose is freed from the covering material and pruned, nitrogen fertilizers are applied - 25-30 g of nitrate per square meter of soil. After 10-14 days, feeding is repeated.
- When buds begin to form, the rose is fertilized with nitrogen-based complex compounds. It is best to use specialized fertilizers such as "Kemira-Lux", but you can also work with Azofos.
- Before flowering, they are fed again with organic matter - infusions of mullein or droppings in the same amount as when planting.
- After the first flowering has passed, they fertilize with complex fertilizers, but very little nitrogen is needed here. It is better to do without it during this period.
- Finally, after the rose has completely bloomed, it is fed with superphosphate. The dosage is about 30 g per square meter of soil.
As for the looseness of the soil, before planting it is dug at least 70 cm deep in two steps (the upper layer is removed, the lower layer is loosened, then it is poured back and the removed upper layer is loosened). Also in the summer it is worth weeding the bush from time to time and loosen the soil around the roots.
2. Dichki
Growth often comes from the roots of a rose - small shoots stretching upward. If there is too much of it, then it will drown out the rose itself. The shoots are cut at the root immediately after emergence. It is still not needed for anything: only a rosehip will grow from the roots of a rose.
3. Bust with nitrogen
Nitrogen compounds are needed for the growth of green mass, but if there is too much nitrogen in the ground, the rose will begin to grow vigorously shoots and leaves, forgetting about flower buds. Therefore, you should be careful with organic matter and saltpeter. Better to add more potassium and phosphorus.
4. Diseases and pests
Climbing roses are susceptible to diseases such as powdery mildew or bark cancer. In addition, aphids, leafworms and other pests attack them. To avoid problems with this, treat the rose from the fungus with Bordeaux liquid or a solution of copper sulfate (1%, the treatment is carried out on dormant buds). To avoid bark cancer, use prevention:
- feed potassium and phosphorus in September;
- cover the rose securely for the winter, avoiding frost damage;
- cut off diseased shoots;
- protect the covered rose from dampness during the thaw.
As for pests, insecticides will help from them.
5. Landing error
If the rose does not bloom, the location of the flower bed may be to blame. Like all roses, climbing species do not tolerate shading, love airing, but do not tolerate northern winds and drafts. To remedy the situation, transplant the rose before it's too late.
6. Bad wintering
In order for the rose to be healthy, it must be protected from frost. But at the same time, between the shelter and the rose, there should be a layer of air that protects not only from temperature, but also from dampness. During the thaw, the plants need to be ventilated, and before wintering, the rose should be allowed to retire: with the end of flowering - no nitrogen fertilizers (potassium and phosphorus is possible), the soil is not loosened, watered slightly less. Any root growth and damaged shoots must be cut out before wintering.
7. Pruning errors
When caring for a climbing rose, you need to cut out root wilds and old shoots, but you should not get carried away. If you cut too many young shoots, the plant will drop everything.
strength to restore the crown, and not to bloom.
In short, follow the rules for growing roses - and you will not have any problems with their flowering!
