Rose is very popular with flower friends, and many friends around them have it. In spring, everyone will ask: how are your rose flowers blooming? Now that it's summer, you don't have to meet and ask: how is your rose? Are the leaves yellow? Rose is a famous medicine jar, especially in summer, when the climate is uncertain and bacteria are abundant, it is the season with the most yellow leaves.

There are many reasons for the yellow leaves of the rose, and if many flower lovers deal with the cause without knowing the cause, it is easy to cause secondary damage to the rose and accelerate the death of the rose. Today, the little assistant will come to analyze all kinds of yellow rose, how to prevent and prescribe the right medicine.

1. Hot yellow. The main characteristics of hot yellow are that there is no obvious change in the old leaves, the new leaves become dark yellow and no luster, the branches are small and yellow-green, and the new shoots are not long. If the hot yellow is serious, the root of the rose is rotten and the whole plant is yellow.

The main causes of hot yellow are: if the flowerpot is relatively small and thin, it is most vulnerable to injury in summer; direct exposure of rose plants at noon in summer will also be caused; and it will be cloudy and sunny in summer, and it will rain for a while. It's easy to cause a lot of root death.

How to prevent and cure: if it is hot yellow, immediately move the rose potted plants to a shady place, cut off the yellow leaves, more than 5 leaves, and then use rooting powder to irrigate roots and spray leaves for treatment.

2. Hungry yellow. Hungry yellow is caused by insufficient fertilization or too long interval between fertilizations. the main feature is that the new leaves are yellow first and the old leaves look normal. If it can not be fertilized in time, it will also cause yellow leaves and even death of the whole plant.

Rose is fattening, especially in the growing period or early flowering period, it must be given enough nutrients to blossom. Rose fertilizer can choose a special nutrient solution for rose, which is rich in nitrogen, phosphorus and potassium, which can effectively prevent yellow leaves.

3. Dry yellow. The main characteristics of dry yellow are that the edges of the leaves are yellowing and dry, the old leaves are the first to be hurt, and the new leaves can grow normally. If there is a lack of water for a long time, the whole plant will be yellow and die.

This symptom usually occurs only after a week of severe water shortage, which should be watered immediately after discovery, and then moved to the semi-overcast ventilated place. Don't fertilize the rose at this time, it will accelerate the death rate of the rose.

4. Fat yellow. The main feature of fat yellow is that the new leaves are relatively thick and shiny, the leaf surface is uneven, and the top of the rose will be dry brown. The whole piece of the old leaf is scorched yellow and will fall off if it is serious. The cause of fat yellow is mainly caused by fertilizing too hard or using too high concentration.

At this time, you should stop fertilizing, then wash the fertilizer off with flood water or change the soil directly, and then put it in a cool and ventilated place for a period of time, waiting for the leaves to recover.

5. Iron deficiency and yellow. This kind of yellow often appears in the newly bought rose, that is, the so-called greenhouse seedlings. Due to the great changes in soil fertility and environment, yellow leaves will appear soon after being bought by flower friends. The main feature is that the veins are green, the leaves show yellow leaves, and the new leaves are more obvious.

When you buy this kind of greenhouse seedlings, you should generally put them in a semi-shaded ventilation place, and then spray some ferrous sulfate solution every week for about 3 weeks. When the rose adapts to the environment, it can be nursed normally.

6. Water is yellow. This is also the yellow leaf where the little assistant encounters the most advice from flower friends, because about 80% of the flowers die because of watering problems, but flower friends have no idea. You can use the flower and plant detector to monitor the water and fertilizer of the basin soil, insert it into the soil, and view the data at a glance through app, which is very simple and convenient.

The main characteristics of water yellow are yellowing and dull on the surface of old leaves, dull new leaves and short atrophy of new buds. If it is determined that the rose is yellow, immediately control the water, do not fertilize, remove the basin, then put it in a cool and ventilated place to dry the soil for seven or eight minutes, and finally reload the basin.

In fact, the most important thing to raise rose in summer is to raise roots. you can usually use a special nutrient solution for rose, which is rich in humic acid, which can promote rooting. According to the growth habits of rose, you can apply fertilizer once every 10-15 days, and you can irrigate roots or spray leaves. But do not spray fertilizer on the flower bud during the flowering period, it will die.
