There are many similarities between the cultivation of rose and rose, and compared with the cultivation of rose is more extensive, in our country, we can often see its figure in roadside, field side or mountain and hilly bushes, which has strong adaptability and vitality. But when we are breeding, many people still find that the leaves of roses turn yellow when they are raised. How is this going on? Below the pro-agricultural network to introduce to you how to yellow rose leaves related issues.

With regard to the reasons for the yellowing of rose leaves, the pro-agricultural network summarizes three points here. The causes of rose leaves yellowing are mainly related to watering, fertilization and diseases and insect pests. Let's take a specific look.

I. improper watering

Rose likes a warm and humid environment, is not resistant to waterlogging, and can withstand drought and barren. When watering, if you are not careful to cause the basin soil to be too dry or too wet, it may cause the leaves to turn yellow.

Solution:

The best way to solve the problem of yellow leaves caused by improper watering is to master the correct watering method. From the beginning of sprouting in early spring to flowering, it should be watered according to the weather conditions, generally watering 3 or 4 times to keep the soil moist. If watering is reduced, the number of flowers will be affected. It was watered 2-3 times in summer and 2-3 times in autumn to ensure that the roots did not accumulate water.

2. Improper fertilization

Roses are usually fertilized in autumn, and if fertilized too early, it will affect the growth of roots. At the same time, there should be a clear check on the amount of rose fertilization, too much fertilization will lead to root burning; too little fertilization, nutrients can not meet the needs of the normal growth of roses, which will lead to yellowing leaves.

Solution:

Mastering the correct fertilization method is the key to solve this problem. Do not apply fertilizer immediately after planting the rose. If the rose is very thin, you can spray foliar fertilizer properly and apply fertilizer in the soil in autumn. Such as urea, potassium dihydrogen phosphate solution, pay attention to the content of nitrogen fertilizer, not excessive, so as not to cause branches and leaves to grow and affect flowering.

III. Diseases

Disease is the only cause of leaf yellowing that is not caused by human factors. After common diseases: black spot, powdery mildew, rust and so on, these diseases will leave different degrees of spots on the leaves, light will lead to leaf discoloration, serious will lead to leaf shedding and even plant death.

Solution:

The emergence of diseases is bound to lead to a great loss of plant vitality, so we try our best to avoid the problem of diseases and insect pests in the process of breeding, and do a good job of prevention in time. Usually maintenance should pay attention to observation, once found that the traces of disease erosion should be dealt with immediately, spray the corresponding agents to treat. At the same time, the rose is also a kind of plant that can stand pruning, which can prune the dense branches and old branches every winter, which can strengthen the ventilation of plants and reduce the probability of diseases and insect pests to a certain extent.

The above is the pro-agricultural network to introduce to you about the rose leaves yellowing reasons and treatment methods, I hope to bring you some help. Through this article, we can see that the main reason for the yellowing of rose leaves is that our daily maintenance is not in place, and we do not know enough about the growth habits of this plant, so the first thing we should do before breeding is to understand this plant. Only in this way can we avoid too many problems in the breeding process.
