In the flower shops you can buy charming miniature roses of any color. As a rule, the splendor of the bushes is achieved by planting several plants in one pot at once. Unfortunately, the houses of roses can quickly lose their attractiveness: shoots wither, leaves turn yellow, buds crumble.

What caused premature wilting and why do the leaves fall off the roses? Manufacturers plant plants in small pots filled with a mixture of special soil and fertilizers. Already in the store, the roots begin to suffer from a lack of space, the earth clod quickly dries up, the supply of nutrients runs low. This can lead to a strong oppression of the bush, and even to their death.

The main reason why the leaves fall off the rose is a sharp change in lighting and temperature conditions. The plant is stressed, it needs to get used to the new conditions of detention. Roses love direct sunlight, coolness and fresh air. If they get it, they can grow and develop in their new home.

Another reason is the drying of the land. The flower should be well watered. As soon as the shop rose blossoms, it needs to be transplanted into a more spacious pot in good nutrient soil. To maintain moisture, spray the plant with sedimented water. They do not like roses and overflow. They need good drainage, there should be no stagnation of water at the roots.

Often the spider's mite attacked the house flowers, the room rose also suffers from it .

Garden roses

For the successful cultivation of healthy shrubs, pleasing with prolonged flowering, one must plant flowers on sunny areas with good air circulation. The reasons why the leaves fall off the roses in the open ground, there may be many: errors in care, infectious diseases, invasion of pests.

Pests

Garden roses have many enemies among insects. In dry weather, a rose cicada and a spider mite can attack the leaves . They feed on the juice from the lower surface of the leaves, causing them to dry out. Very quickly settled throughout the rosary, so at the first signs of the appearance of insects, you need to start spraying with plant infusions or insecticides.

The rose sawfly is another parasite, from which the rose suffers. The leaves turn yellow and fall, the young shoots die because of the strokes that the insects' false larvae gnaw through the stems. Affected areas must be cut and burned.

Application of fertilizers

Roses need a lot of minerals and trace elements. Lack of nutrients can lead to the development of diseases.

1. Chlorosis : occurs with a deficiency of magnesium. It affects first the old leaves, then the young ones. The edges remain green, and between the veins appear yellow and red dead spots. Then the leaves fall off. To eliminate chlorosis plants must be supplemented with magnesium sulfate.
2. Lack of nitrogen . The leaves become light green or yellow, their growth slows down or stops. Usually the problem occurs in early summer. To correct the situation, it is necessary to introduce nitrogen fertilizers.
3. Iron deficiency . The young leaves turn yellow, but the veins remain green. Often occurs on zemesified soils. To make up for the missing element, it is necessary to treat plants with iron sulfate solution or to make complex fertilizer.
4. Lack of manganese is similar, but it affects the old leaves first. Potassium permanganate or manganese sulphate must be added to the plant.

Infections

The most common infectious disease is black spotting. Markings appear both on leaves and petioles. Around them yellow areas are formed. They expand, as a result of which the entire leaf turns yellow and falls off. Spreads in heated damp weather. Weakened, bare plants do not tolerate winter well, therefore, it is necessary to fight infection.

Affected leaves and plant debris should be scrapped and burned, and the plants treated with fungicides.
