In 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 at once in one pot. Unfortunately, at home roses can quickly lose their attractiveness: shoots wither, foliage turns yellow, buds crumble.
What causes premature wilting and why do the leaves of a rose fall? Producers 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, an earthen lump quickly dries up, the supply of nutrients runs low. This can lead to severe oppression of the bushes, 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 under stress, 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 overdrying of the earth. The flower should be well watered. As soon as the store rose fades, it needs to be transplanted into a more spacious pot in good nutritious soil. To maintain moisture, it is necessary to spray the plant with stagnant water. They do not like roses and overflow. They need good drainage, there should be no stagnation of water at the roots.
Often, spider mite attacks home flowers; the indoor rose also suffers from it . The leaves fall, a white coating appears on their underside, small, barely distinguishable parasites crawl along the plant. The flower and the earth in the pot must be treated with special preparations, and try to provide him with sufficient humidity and an influx of fresh air.
Garden roses
For the successful cultivation of healthy bushes, pleasing prolonged flowering, it is necessary to plant flowers in sunny areas with good air circulation. There can be many reasons why the leaves of a rose fall in the open ground: errors in care, infectious diseases, and pests.
Pests
Garden roses have many enemies among insects. In dry weather, rosan cicada and spider mite can attack the leaves . They feed on the juice from the bottom of the leaves, causing them to dry out. They spread very quickly throughout the rosary, therefore, at the first signs of the appearance of insects, it is necessary to start spraying with plant infusions or insecticides.
The rodent sawfly is another parasite from which the rose suffers. The leaves turn yellow and fall, young shoots die due to passages that gnaw through the caterpillars of this insect inside the stems. Affected areas must be cut and burned.
Fertilizer application
Roses need a lot of minerals and trace elements. Lack of nutrients can lead to the development of diseases.
- Chlorosis : occurs with magnesium deficiency. It affects first the old leaves, then the young. The edges remain green, and between the veins yellow and red dead spots appear. Then the leaves fall off. To eliminate chlorosis, plants need to be fed with magnesium sulfate.
- Lack of nitrogen . Leaves turn light green or yellow; their growth slows down or stops. Usually the problem occurs in the early summer. To correct the situation, you need to make nitrogen fertilizers.
- Iron deficiency . The surface of young leaves turns yellow, but the veins remain green. Often occurs on well-known soils. To make up for the missing element, it is necessary to treat the plants with a solution of iron sulfate or to introduce complex fertilizer.
- Lack of manganese appears similarly, but first affects the old leaves. It is necessary to add potassium permanganate or manganese sulfate under the plant .
Infections
The most common infectious disease is black spotting. Marks appear on both leaves and petioles. Around them yellow areas form. They grow, as a result of which the entire leaf turns yellow and falls off. Distributed by spores in warm, humid weather. Weakened, bare plants do not tolerate winter well, therefore, infection must be controlled.
The affected leaves and plant debris must be scooped up and burned, and the plants treated with fungicides.
