The queen rose in the flower, also known as "moon red", it blossoms in four seasons, usually red, or pink, occasionally white and yellow, can be used as an ornamental plant, can also be used as a medicinal plant, then, how much is it? How should we deal with the yellowing of leaves?

How much is the monthly flower per plant?

Note: there are nearly ten thousand species of rose in the world and more than one thousand in China. Its market price is determined by specifications, varieties and sales areas. Usually, the larger the specification, the more unique the variety, the more expensive the market price.

Second, what should be done if the leaves turn yellow?

If the leaves of rose flowers turn yellow during culture, we can consider whether it is caused by the following factors:

1. Overwatering

[reason] the young leaves of rose are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered.

[methods] put the flowers out of the pot in a ventilated, cool and self-drying soil mass and then put them back into the basin.

2. Insufficient watering

[reason] the yellow of lack of water in rose is different from the yellow with more water, the yellow of lack of water is withered and dry at the tip or edge of the leaf, and the old leaves wither and fall off from the bottom up, but the growth of the new leaves is relatively normal.

[method] pay attention to watering enough and thoroughly.

3. Direct exposure to strong light

[reason] when the strong sunlight shines directly on some flowers that like shade, it is easy to cause the withering of the leaf tip and leaf edge, and the macula appears in the sunrise part of the leaf.

[method] it can be moved to the shade.

4. Lack of light

[reason] when the rose was placed in a shady environment for a long time, the leaves did not get enough sunlight and could not form chlorophyll, and the whole leaves turned yellow and fell off.

[methods] just supplement the light.

5. Excessive fertilization

[reason] the yellowing of flowers caused by excessive fertilization or excessive concentration of rose shows dry brown at the tip of the new leaves, the leaves are generally thick and dull and concave and convex, and the old leaves are scorched yellow.

[methods] Fertilizer should be stopped immediately and some fertilizers should be washed with a lot of clean water seriously.

6. Insufficient fertilization

[reason] insufficient fertilization of rose led to light color of young leaves, yellow or light green, while old leaves were relatively normal or gradually changed from green to yellow.

[methods] check the basin soil, if there is a dry knot phenomenon should change the soil, usually apply thin fertilizer frequently and pour some alum water at the right time.

7. Potted soil problem

[cause] the consolidation of basin soil leads to poor soil permeability and difficulty in breathing in the roots of plants, which affects plant growth.

[methods] use bamboo sticks to insert more than a dozen holes in the basin to ensure that the roots are ventilated.

8. Poor ventilation

[reason] Rose likes the environment of air circulation, in the environment of lack of ventilation and stuffy air, it will also make rose leaves yellow and long macula.

[methods] the rose can be cultured in a well-ventilated and well-ventilated environment.

9. Virus attack

[cause] the roots, branches and leaves are damaged by the virus, and the leaves are not stretched and accompanied by yellowing and lifeless symptoms.

[methods] when spraying virus gram, gram dew and other prevention and control, attention should also be paid to maintenance and management, and robust plants will generally not be infringed.
