Why do rose leaves keep turning yellow and the plant just won't grow well?
Roses are a flower that many people love very much, and many people grow them in everyday life. They are also one of the world's famous ornamental plants. Roses are very beautiful when they bloom, but some people also find that when growing roses, the leaves keep turning yellow and never seem to recover, so what exactly is going on?
1. Caused by improper watering
Roses like moisture but are afraid of being too wet or waterlogged, so watering needs to be controlled with special care. However, many times when watering, people always end up watering too wet or too dry, that is, watering too much or too little, and either of these can cause rose leaves to turn yellow due to improper watering. So when watering roses, you must do it appropriately, and you must be careful not to let water accumulate at the roots of the rose.
2. Improper fertilizing causes rose leaves to turn yellow
Fertilizing is something every kind of flower must go through during care, and roses are no exception. There are certain techniques to fertilizing: you need to prevent yellow leaves caused by a lack of fertilizer or too much fertilizer. When fertilizing roses, you should wait until autumn to apply an appropriate amount of fertilizer to the soil; before autumn, you can spray a small amount of fertilizer on the leaves of the rose. Do not fertilize too early, to prevent the situation of burning the rose's roots.
3. Caused by roses getting rust disease
Rust disease is a very common disease of roses. Both the leaves and new branches of roses can get rust disease. If you find that a rose has rust disease, it should be treated promptly. The treatment method is to spray an 800-fold dilution of triadimefon on the leaves; generally spraying once a week is enough, and after spraying three or four times the rust disease can be resolved.
If it is not dealt with in time and the rust disease becomes severe, it may cause the rose's leaves to turn yellow to the point of large-scale leaf drop. This not only affects the rose's appearance and greatly reduces its ornamental value, but in severe cases it can also cause the plant to die. So if a rose gets rust disease, it must be treated promptly.
