Why do roses wither

There are four main reasons why roses wither. The first reason is improper watering. Lack of water will cause roses to wither, especially in places with high temperature. The second reason is that improper fertilization of roses and excessive fertilization will lead to burning seedlings and withering. The third reason is that the lack of light needs to be transferred to sunny conditions.

The cause of rose wilt 1, improper watering.

The sudden withering of roses may be due to improper watering, especially in the case of high temperature in summer. If the weather is hot, water the roses twice a day, once in the morning and once in the evening. Lack of water or improper watering time can cause roses to wither. It is not allowed to water too much, which will lead to water accumulation. It is necessary to follow the principle of seeing dry and seeing wet, with a small amount for many times.

2. Improper fertilization

Improper fertilization can also cause roses to wither, especially when fertilization is excessive. When the temperature of roses is not suitable, a large amount of fertilizer will be applied, which will lead to the failure of fertilizer absorption and accumulation in the root system. If the concentration is too high, it will affect the water absorption of plants, lead to physiological drought and even burn seedlings. At this time, fertilization should be reduced, and fertilization should be combined with watering to reduce fertilizer concentration.

3. Insufficient light

The growth of roses needs sufficient light to increase the formation of chlorophyll, ensure the intensity of photosynthesis and provide sufficient nutrients for the plants themselves. If plants will wither due to lack of nutrition in the case of long-term lack of light, move them to a place with sufficient light or light, and sing the daily light time.

4. Pest infection

Roses will wither when infected with pests and diseases. There are many reasons for diseases and insect pests. One reason is the climate, such as hot and humid weather. In the early stage, corresponding chemicals can be sprayed to control pests and diseases. Another reason is the problem of training and management. Branches overlap each other, and air tightness and light transmission can also lead to pests and diseases. It is necessary to prune the branches and leaves in time.
