Chinese rose is a famous flower variety, which is distributed in many parts of our country. Now many people will choose monthly knot to breed, mainly because it has a very high ornamental value. However, many people in farming because of improper methods of fertilizer and water, leading to some problems, so it is very important to master the skills of fertilizer and water.

How to water rose flowers

Spring is the season of sprouting and growing branches of rose flowers, and the supply of water is very important. In March, the new leaves grow and water once every two days, in the morning; in April, the flower buds gradually form and water once a day; in May, they enter the flowering stage, watering twice a day, usually once at about 8 o'clock in the morning, and replenish water according to the dry and wet condition of the basin soil at about 4 o'clock in the afternoon. In other seasons, according to the principle of "no dry, no watering, watering thoroughly", when the summer weather is hot, you can spray water to cool down properly.

Fertilization method of rose flower

The rose should be fertilized with thin fertilizer and diligent fertilizer. Before sprouting in spring, fertilize once and choose mature human dung, bean cake and so on. When the bud is ready to bloom, add a light liquid fertilizer. After the summer flowers wither, apply a rotten liquid fertilizer to promote autumn flowering. A small amount of organic fertilizer was applied to the roots in winter to enhance the disease resistance of the plant.

How to prune the dormant period of Chinese rose

1. When the rose flowers are dormant, they also need to be pruned. It is generally pruned before and after the Spring Festival to cut off disease and insect branches, withered branches, overlapping branches and cross branches on rose plants.

2. In the meantime, rose flowers need to be pruned, and rose flowers with poor growth should be strongly cut, generally cutting off 2/3 of the branches. Better growing rose, a little pruning, cut off some of the branches and leaves on it.

3, potted rose pruning is different, if the rose plant is small, it is best not to prune, slightly larger rose plant, according to the height of the plant, the appropriate truncation.

4. If the rose is overwintering in the open field, it should be noted that it is generally not pruned. This is to prevent the rose from being frozen and injured in winter. Just wait until spring for pruning.

What if the leaves of Chinese rose turn yellow?

1. Improper watering. You need to remove the plant from the pot and put it in a cool, ventilated place and wait for the soil to dry before putting it back into the flowerpot. The yellow with too little water is different from the yellow with too much water, the yellow with less water shows that the leaf tip or edge is dry and withered, the old leaf is withered and yellow from the bottom up, while the growth of the new leaf is relatively normal. When watering, pay attention to "do not dry do not water", watering should be thoroughly watered to ensure sufficient water.

2. Improper fertilization. In the early stage of growth, it is best to apply light fertilizer frequently, mainly compound fertilizer, and adopt the method of hole application or pouring. Do not apply immature organic fertilizers and large amounts of chemical fertilizers, which can burn roots, causing plants to wilt and die.

3. Viral yellow leaves. Can spray virus gram and gram dew and other solvents, but to a comprehensive maintenance and management-based, robust plants will have a strong resistance.

4. It is improper to change the basin and soil. Although the work of changing the basin and soil sounds very simple, it is not easy to make the root system combine closely with the soil. You can use small sticks to help stabilize or gently pier the soil. The application of base fertilizer should choose mature fertilizer and stay away from the root system as far as possible. Avoid direct contact with the root. After changing the basin, the water should be watered thoroughly, maintained in a cool place, and the second watering should be carried out when the basin soil is slightly dry, and then the watering principle of "no dry, no watering" should be followed. There is no need to apply fertilizer for a short time after changing the basin, and it will be fertilized at least three weeks later. In terms of changing the soil, if there is lime powder or too much acidity in the soil, it will also cause the leaves to turn yellow.

When watering rose flowers, we must pay attention to the amount, not too much. Pay attention to time when you are fat and watery. In addition to fat and water, the rose also needs to be pruned in order to ensure its growth. If the rose leaves yellowing phenomenon, you can observe the cause, and then solve the problem from the root.
