Why does a rose curl leaves and dry
Content:
The rose can be called one of the most beautiful flower cultures. Thanks to the variety of varieties, it has become very popular among flower growers. But not always when growing rose bushes everything goes smoothly. Often, flower growers are faced with such a problem as leaf curling.
Garden roses have leaves curling inward - is this normal or not?
Normally, a healthy rose flower has an elastic leaf plate, there should be no stains or rust on it. If the leaves are curled, then something is happening to the bush. In cultivation, mistakes were made that led to this result. As soon as the first twisted leaves appeared on the bushes, you need to immediately understand why this happened and how to solve the problem.

Causes of leaf curling
If twisted leaves appear on the rose bush, then the care of the flower is incorrect. It is necessary to find and eliminate the cause as soon as possible before the plant dies.
Why do the leaves of a rose curl? This can be due to a lack of moisture and high temperatures. When growing roses in the garden, it should be borne in mind that the plant, unlike most other crops, loves coolness. But too low temperatures also negatively affect the growth of the flower. Sudden changes in temperature and cold drafts often cause the sheet plate to twist inward.
Another factor contributing to leaf deformation is improper watering. Flowers should not be watered with ice water. It is also not recommended to irrigate the soil during the day when solar activity is high. Because of this, burns appear on the foliage.
Roses are very demanding on lighting. Plants hardly tolerate prolonged darkening, but they also grow poorly in the open sun. It is best to choose such a site in the garden so that the bushes are in partial shade. Prolonged exposure to bright sun leads to the appearance of spots, diseases and deciduous mass.
Another reason why the leaves of a rose curl are viral diseases. You can immediately notice that a flower is affected by any disease. Leaves can curl outward, wither and fall off. As a rule, diseases develop very quickly and, if measures are not taken in a timely manner, the bush may die. Most often, the culture is sick with powdery mildew, rust and gray mold. The danger of viral diseases is that they are problematic and difficult to cure.
A common reason why rose leaves curl is the appearance of pests. Most often, insects destroy young juicy leaves.

The lack of fertilizers in the soil also negatively affects the growth and development of flower crops. The first sign of a lack of potassium in the soil is foliage curling into a tube.
Ways to eliminate leaf curling
Before deciding what to do if a rose has curled leaves, you need to find out the reason. First of all, rose bushes need to be properly cared for and all violations eliminated.
Crop care rules:
- If the flower is grown at home, it is imperative to fill up the drainage when planting in a pot.
- Watering should be regular, but it is important not to overflow the soil and prevent it from overdrying.
- Fertilization is required several times a month.
- The soil should be weeded regularly and weeds should be pulled out.
- In order for water to evaporate from the soil more slowly, it must be mulched.
- It is good if the watering is drip.
- It is not recommended to plant bushes too close to each other.
- You can not plant seedlings under the spreading crown of trees. They will experience not only a lack of sunlight, but also nutrients.
The most difficult thing is to organize the correct fertilization. Not only a deficiency, but an excess of nutrients negatively affects both the leaves and the buds.
Fertilizers are applied to the soil only during the active growing season. This should be done after the bush wakes up from hibernation and buds begin to appear on it. In the first half of the summer season, when the flower is actively growing deciduous mass, fertilizers with a high nitrogen content are applied to the soil.
As soon as buds begin to form, nitrogen is no longer added. Instead, the plant should be fertilized with phosphorus and potassium. These substances have a positive effect on flowering. Also, flowers can be sprinkled with wood ash and watered with manure diluted in water.
Another reason due to which the leaf plates can dry is the thickening of the plantings. The bush does not have enough space, so the leaves begin to dry out. To prevent this, you need to pick off small buds and small twigs to thin out the plantings.

Disease and pest control
The most dangerous are pests and diseases. Insects can twist foliage, sucking out all the juices from it. Diseases are difficult to fight.
What you need to do to get rid of pests:
- If pests appear on the leaves, you need to immediately treat the bushes with insecticides or acaricidal preparations. Acaricidal substances are used to combat spider mites, insecticides help from all other insects. For example, "Aktellik" or "Fitoverm".
- If there are not very many pests, you can use folk remedies. For example, a decoction of wormwood or an infusion of onion peel.
- Soap solution can help with aphids. Dissolve laundry soap in warm water and add some wood ash. Mix thoroughly and treat the bushes with a solution.
It is more difficult to fight diseases. Some do not respond to treatment at all.
How to treat diseases:
- With powdery mildew, all damaged parts of the bush must be cut off. The bush itself is processed with copper sulfate, Bordeaux liquid or wood ash infusion.
- If yellow spots appear on the leaf plates, it is most likely a viral disease. It is impossible to cure it. In this case, the bush will have to be dug up and thrown away. The place where he grew up must be watered with a solution of potassium permanganate.
