Rose is very popular and favored by everyone. In the process of breeding, the leaves of desert rose usually turn yellow. Many friends don't know why the leaves of desert rose turn yellow. Xiaobian sums up some of them according to his own experience. Here's how to introduce them to you.
Rose leaves yellow rose leaves yellow reason analysis and treatment methods: 1, environmental change causes rose leaves yellow: bought soon, in the adaptation period, a small amount of yellow leaves is normal and common.
Solution: there is no need to worry about this situation. We can take measures to reduce the degree of environmental change and wait for it to adapt.
2. Excessive watering results in yellowing of rose leaves (yellowing): the leaves are dark yellow and lusterless, the old leaves have no obvious change, the branches are small, yellow and green, and the new shoots shrink not long, indicating excessive watering.
Solution: it is more resistant to drought, each watering amount should not be too much, if more water, it is easy to cause root rot, resulting in yellow leaves.
3. Long term drought causes yellow and curly leaves of rose.
Solution: pay attention to the sufficient and thorough watering.
4. Exposure to the sun causes the rose leaves to turn yellow (scorch yellow): direct sunlight can easily cause the withering of the leaf tip and leaf edge, and yellow spots appear in the Chaoyang part of the leaves.
Solution: the sun is too shady, but also remember not to be exposed to the sun, the leaves are easy to yellow, and affect flowering.
5. The air drying causes the rose leaf to turn yellow: the flower soil is too dry, if the soil in the basin has not been watered for a long time, it can also cause the leaf surface to turn yellow.
Solution: place it in a cool room, avoid direct sunlight, and pay attention to watering.
6. The lack of sunlight leads to the yellowing of rose leaves (lack of light yellow): if the leaves are exposed to shade for a long time, they can not get enough sunlight to form chlorophyll, and the whole leaves turn yellow and then fall off.
Solution: if the light is not enough, there will be yellow leaves. If it is serious, the whole plant will rot and die. You can move the plant to a place with enough light, but remember not to expose it to the sun.
7. Too high temperature leads to yellow rose leaves: leaves curl yellow, the whole plant wilt.
The solution: put the plants in the shade.
8. Too low temperature leads to yellow rose leaves: when the temperature is low, the winter will be in a dormant period, that is, the leaves turn yellow and lose leaves, or even fall into bare stems.
Solution: solution: can be appropriate insulation, temperature should not be less than 8 degrees.
9. Excessive fertilization leads to yellowing of rose leaves (yellowing): excessive fertilization leads to yellowing and withering of old leaf tips.
Solution: suspend fertilization, and add topdressing according to the growth situation when a large number of new buds appear in spring.
10. The long-term lack of fertilizer led to the yellowing of rose leaves (lack of fertilizer yellow): the new roots turned yellow, the leaves became light green, and then gradually turned yellow and dry.
The solution: appropriate fertilization, not more fertilization.
11. Rotten roots lead to yellow rose leaves: the flowerpot is airtight, and the big root is small, so as to avoid the long-term moisture of the pot soil, causing root rot.
Solution: it is necessary to replace the flowerpot with air permeability and place the plant in a dry place.
12. Diseases and insect pests lead to yellow leaves of roses: leaf spot and root rot damage, leaf spot can cause a large number of leaves to fall off when it is serious, and there are earthworms or golden needle insects (red spider, beetle) and other pests in the basin soil, and the symptoms of yellow leaves will also appear.
Solution: go to the flower market to buy carbendazim or tobramycin, which are commonly used drugs, and then spray them in water according to the proportion.
Fresh rose maintenance experience: finally, we need to pay special attention to: whether it is in the adaptation period or dormancy period, we should control watering and suspend fertilization. When a large number of new buds appear in spring, top dressing should be added according to the growth situation. In winter, it can be placed in a sunny place and keep the basin soil dry. The minimum temperature should not be lower than 8 ℃. In other seasons, it can be placed in the sunshine area, not in the dark, otherwise, even if watering and fertilization are normal, the yellow leaves will fall off due to the lack of light.
