Rose is a more common flower, raised by a lot of people, encountered a lot of problems, is a famous medicine jar. Summer is coming, all kinds of problems of the rose come one after another, which really worries the flower friends, and all kinds of yellow, diseases and insect pests can not make people worry. Today, let's take a look at the main factors that cause the yellow leaves of the rose.

1. Watering problem. Many flower lovers can't control their hands, and 80% of the flowers are watered to death. In summer, under-watering or too much watering is most likely to lead to rotten roots of yellow leaves. Watering too much is easier to judge, the old leaves will not be affected, the new leaves will be yellow micro-curls. At this time, just take off the plant and put it in a cool and ventilated place, blow-dry the soil and then put it back into the flowerpot. If the water is too little, it can be watered directly, how to judge it? That is, every time it is watered slowly around the plant, it has been watered in a circle until the water flows out from the bottom of the flowerpot.

2. Fertilization. At the beginning of summer, many roses will enter the semi-dormant period, but will continue to blossom, so it still needs to apply a little thin fertilizer. If the rose is given an immature organic fertilizer or a large dose of chemical fertilizer at this time, it will burn the roots, wilt severely and die.

The best way to fertilize the rose is to choose a special organic nutrient solution rich in humic acid. The nutrition is balanced and the plant absorption will be better. In summer, you only need to exchange 1ml for water above 1000ml, which can be irrigated or sprayed with leaves, and fertilized once every 15 days. Be careful not to apply fertilizer during the flowering period, and do not splash fertilizer on the bud when applying fertilizer, it will fall off.

If you really don't know how to control the time of fertilizing or watering the rose in summer, you can use a flower detector to help. Just insert the detector into the soil of the flowerpot and link to the phone to display the data of water and fertilizer, teaching you how to water and fertilize scientifically.

3. Diseases and insect pests. Rose is a famous medicine jar truly worthy of the name. In June, aphids, powdery mildew and black spot are all common diseases of rose. If you are not careful, the leaves of rose will become unstretched and accompanied by yellowing. Careful flower friends can look behind the leaves of the rose and find that there are bugs one by one.

If you suffer from diseases and insect pests, you only need to buy some insecticides, such as carbendazim and dimethoate, which can be used in accordance with the instructions. If it is really serious, you can also artificially pinch the insects to death before spraying them. Usually when watering, you can develop your own fermented garlic water to water the rose, which can play a role in preventing diseases and insect pests.
