A blossoming rose can become a real decoration of a suburban area. However, decorative culture is, unfortunately, rather capricious. Care for roses in the garden must be done correctly. Sometimes gardeners with such plants have all sorts of difficulties. For example, in some cases, buds may not bloom on rose bushes. The reasons for this unpleasant phenomenon are different.
Why don't roses bloom
The main reasons for the death of the buds of this culture before blooming are:
- wrong care;
- diseases;
- insect attack.
People who grow almost any variety of roses on their plot may face the problem of lack of flowering. But some varieties of this plant are still considered resistant to the death of buds.
Early flowering
Very often, the death of the buds of this ornamental culture occurs precisely for this reason. In gardens and parks, roses usually bloom in mid-June. Appearing at the beginning of this month and even more so at the endMay buds must be removed. In spring, the weather outside in central Russia, the Urals and Siberia is quite cool. And the roses themselves during this period may not be strong enough after the winter cold. Accordingly, the plant will simply not have enough strength to bloom.
Why Roses Don't Bloom: Rotting
Another reason for the death of rose buds before flowering is poor ventilation of the crown. The bushes of this ornamental culture should not be too thick. Otherwise, the moisture balance in the crown of the rose will be disturbed. As a result, some parts of the plant will begin to rot. And first of all, this will, of course, affect the delicate and fragile rosebuds.
In order for the bushes to subsequently bloom profusely and for a long time, in the spring they must be checked and, if necessary, cut. Following this procedure, you should remove:
- frozen ends of shoots;
- frozen shoots.
You also need to check the bushes for the presence of incorrectly growing branches left over from autumn (for example, directed inside the crown).
Why do rose buds dry without blooming: burns
This is another reason why flowers may not open. The buds of this culture usually get burnt after "blind" rains. In this case, drops of water remain on the tender, developing rose petals, acting like lenses in the sun. Particularly susceptible to burns are varieties with flowers of considerable diameter with a large amount ofpetals. In this case, both the buds themselves and already blossoming roses can dry up and fall off in plants.
To avoid such a problem, in hot weather, the branches of bushes with a large number of buds should be hidden in the very thick of the crown - under the foliage. If there is a possibility of "blind" rain, you can even pull a temporary awning made of waterproof material over the plant.
And of course, you can water roses, including by sprinkling, only in cloudy weather, in the morning before sunrise or in the evening after sunset.
What diseases can interfere with flowering
Improper care causes the death of rose buds quite often. Fixing the problem and achieving abundant flowering in this case is usually quite easy. The situation is slightly different when the problem is caused by some disease. In this case, in order to achieve flowering roses, the gardener will have to work hard.
If the rosebuds do not bloom and dry, the garden owner, among other things, should check the bushes for symptoms of diseases such as:
- grey rot;
- powdery mildew.
Bray mold is the most common cause of non-blooming. In this case, rosebuds and pedicels are covered with a coating of the corresponding color. Further, these parts of the plant begin to dry out and die. Gray plaque with this disease can also form on other parts of the plant. But most of all in this caseit is the buds that suffer.
When powdery mildew, a white coating appears on roses. It can cover both the stems of the plant, and its leaves and flowers. In this case, rose buds do not open and flowering does not occur.
Gray rot: how to fight
If the dropping of buds is caused by just such a fungus, the rose needs to be treated using some kind of biofungicide. It could be, for example:
- "Phytodoctor".
- Planris.
- Fitosporin.
- "Trichophyte".
If the rot hit the plant very badly, more serious means will most likely have to be used for spraying. It can be, for example, Switch, Teldor, Fundazol.
From folk remedies to combat gray rot, a milk-water solution (1/10) and a decoction of ash (300 g per 10 l) are often used. The same compositions can also be used to prevent infection of roses with gray rot. In addition, in the spring, to prevent infection with a fungus, the bushes of this ornamental crop can be sprayed with Bordeaux liquid 5%.
Prophylactic treatment of roses from gray rot should be done without fail. The disease is really very serious and dangerous. When infected with gray rot, roses can “burn out” in just a couple of weeks.
Powdery mildew control
In this case, fungicides are usually also used for treatment. It can be, for example, "Ordan", "Oxyhom", "Pure Flower". From folk remedies for powdery mildew of roses is goodiodine (10 ml per 10 l of water) and potassium permanganate (2.5 g per 10 l) help.
Can be used for treatment in this case and milk solution. But it is recommended to breed it with powdery mildew in a proportion of ½. For every 10 liters of such a product, it is worth adding 10 more drops of iodine.
Such folk remedies, as well as Bordeaux mixture, can also be used to prevent the development of powdery mildew on plants. When carrying out preventive measures using such solutions, blooming roses are likely to delight the owners of the site throughout the summer.
Disease resistant varieties
Both gray rot and powdery mildew can negate a gardener's best efforts to grow roses. It is quite difficult to fight these diseases even with the use of modern fungicides. Fungal infections develop in roses, usually in wet weather. Therefore, summer residents from humid regions should purchase plant varieties resistant to such diseases.
Powdery mildew, for example, very rarely affects such varieties of roses as:
- Halle.
- Crocus Rose.
- Glory Day.
- Hot chocolate.
Roses with dense buds almost never get sick with gray rot. For example, people who grow the following varieties are unlikely to encounter such a disease:
- Fortune.
- Pastillon.
- Eliza.
Also resistant tothis contagion varieties are Jasmine and Larisa.
Death of buds due to insects
The attack of various kinds of pests is also often the answer to the question of why rose buds do not bloom. Such a problem can be caused, for example, when infected:
- aphids;
- thrips.
Aphids, if you do not take measures to destroy them, can stick around rose bushes very densely. As a result, the plants will begin to bend the shoots, and the buds will stop opening. Of course, roses will not bloom in this case.
When infected with thrips, dark spots appear on the buds of plants. The same formations can be seen on partially or fully blossomed roses. Looking into the middle of the flower, in this case, you can find the actual insects themselves. Thrips have an elongated body shape, and the color is dark. The formed buds, when infected by these insects, are deformed and die.
How to deal with aphids and thrips
Destroy insects on roses, usually using insecticides. It is believed that aphids can help well, for example:
- Spark.
- "Children".
- Aktara.
- Fitoverm.
From thrips on roses gardeners most often use:
- "Aktofit".
- Fitoverm.
- Akarin.
From folk remedies to combat aphids and thrips, summer residents most often use garlic broth. For hispreparations, 3-4 carefully chopped cloves of a burning vegetable are placed in 0.5 liters of boiling water and the remedy is infused for 5 hours. Roses are treated with this solution by spraying.
Indoor varieties
Roses are planted by lovers of ornamental crops, of course, not only in gardens and yards, but simply on windowsills. Such varieties are usually small in size. Problems with flowering in indoor roses occur as often as in outdoor ones. To deal with the death of buds in this case, respectively, follows the same methods. That is, use fungicides or insecticides for this purpose. The only thing is that indoor roses are usually not sprayed during processing. Leaves, buds, shoots and flowers are smeared with prepared solutions using a brush.
