What is the reason why the rose leaves are dry?

Rose is a very popular flower plant in our country. Roses are planted all over our country, and roses can not only be cultivated in the open field. Now, as a kind of potted plant, it is also very popular in our country, but whether it is open field cultivation or potted culture, roses are prone to dry leaves. So what causes the rose leaves to dry up? The following editor will give you a brief introduction, let's take a look at it!

1. Watering reason

Improper watering is one of the main reasons for the drying up of rose leaves. Although roses have a certain demand for water in their growth, they must pay attention to controlling the amount of water when watering. Don't water too much, especially in summer, although the temperature is high, you can't water several times a day. If you water too much, it will cause the roots of the roses to rot because of too much water, thus causing the leaves to dry up. However, water should not be too little, if there is too little water, then the leaves will also dry up because of the lack of water. Therefore, when we are watering, we should water according to the principle of seeing dry and wet.

2. Reasons for fertilization

When planting roses, proper fertilization is very beneficial to the growth of roses. It can advance the flowering rate and blossom time of roses. However, in order to make roses blossom as soon as possible, many people will apply fertilizer blindly, thinking that the more fertilizer, the more roses will bloom, so they apply a lot of fertilizer. In fact, this is very disadvantageous to the growth of roses. Too much fertilizer will lead to too much concentration, which will cause the roots of roses to burn out. If you lose the ability to absorb and transport nutrients, the leaves will wither due to lack of nutrition.

3. Lack of light

Light is very important for the growth of roses. Roses need sufficient light for photosynthesis during their growth. It is also an indispensable substance for the synthesis of chlorophyll in leaves. If the rose lacks light, it will affect the photosynthesis of the rose, resulting in a decrease in photosynthetic matter in the leaves, resulting in gradual yellowing of the leaves. Therefore, we must pay attention to maintain a suitable lighting environment, but the light should not be too strong. In the strong light environment in summer, we should also pay attention to shading work to prevent leaves from being burned by strong light.

4. Temperature discomfort

Temperature is also one of the reasons for the drying up of rose leaves. Roses in the growing period, its growth temperature is about 25-30 degrees, and should be kept at 12-15 degrees at night. If the temperature is too high, it will inhibit the growth of roses, causing roses to stop flower bud differentiation, withered leaves and other phenomena, and will lead to dead seedlings for a long time. When the temperature is too low in winter, the rose will enter the dormancy period and stop growing. If the heat preservation work is not done well, then the leaves will be frozen and withered leaves will appear.
