How is the rose leaf yellowing and growing bad?
The rose is a flower that many people like very much, and many people will raise it in their daily life. It is also one of the world-famous ornamental plants. When the rose blossoms, it is very beautiful, but some people will encounter that when raising the rose, the leaves of the rose always turn yellow and are not always good, so what is going on?
1. Caused by improper watering
Roses like to be moist, but they are afraid of being too wet and waterlogged, and watering needs special control, but very often, when watering, it is always too wet or too dry, that is, too much or too little watering. This may cause the leaves of the rose to turn yellow because of improper watering. Therefore, it must be appropriate when watering the rose, and be careful not to let the roots of the rose appear stagnant water.
2. Improper fertilization leads to the yellowing of rose leaves.
Fertilization is a must for every kind of flower during maintenance, and so is the rose. When fertilizing, we should have certain skills to prevent the problem of yellow leaves of roses caused by lack of fertilizer or too much fertilizer. Roses should apply appropriate fertilizers to the soil in autumn when fertilizing. Before autumn, you can spray a small amount of fertilizer on the leaves of roses. Do not apply fertilizer prematurely to prevent roses from burning roots.
3. Caused by rose rust.
Rust is a very common disease of the rose. The leaves and new branches of the rose may get rust. If it is found that the rose has rust, it should be treated in time. The treatment method can be sprayed with 800-fold liquid triadimefon on the leaf surface, usually once a week, and the rust can be solved by spraying three or four times.
If it does not appear in time and make the rust serious, it may make the leaves of the rose yellow to fall off in a large area, which will not only affect the beauty of the rose, greatly reduce its ornamental, but also cause plant death, so, if the rose appears rust, it must be dealt with in time.
