How to grow rose hips

1. Maintenance methods

1. Temperature: It is best to keep it between 15 and 28 degrees. During its growth and flowering period, the temperature should not be too hot or too low, as both will have adverse effects. Similarly, in summer and winter, it should not be too hot or too cold.

2. Light: Rosa macrophylla likes light. Sunlight will make it grow better and more easily bloom beautiful flowers. However, in the summer, try to provide a shaded environment, because too much light can be harmful. In other seasons, there is generally no need for special shade.

3. Watering: Rosa macrophylla likes moisture, so the watering time can be adjusted according to the season. In winter, since it may be dormant, just keep it not too dry. During the growing and flowering seasons, sufficient water must be provided. Especially in summer, it is generally necessary to water twice a day.

4. Fertilization: Rosa macrophylla likes fertilizer and can be fertilized once every half a month or so, using liquid fertilizer. However, it is not necessary to apply it during the flowering period.

2. Breeding techniques

1. Pruning: After it blooms, the branches need to be pruned. However, special attention should be paid to the degree of pruning and no drastic pruning should be done. Only the dead flowers and branches that look very weak should be cut off. Next, it is about trimming its shape. It can be trimmed into a heart shape, which is more beautiful.

2. Repotting: It is best to repot once a year, and it is more appropriate to do this before winter. Generally speaking, it is more appropriate to use a mixture of garden soil, leaf mold, and rice bran ash. If you need to change the flower pot, it is best to use a clay pot.

3. Problem diagnosis and treatment

1. Diseases: Anthracnose is a disease that threatens many parts of the plant, especially the leaves, which are severely affected. Therefore, thiophanate-methyl can be used for treatment. In addition, the appropriate amount of supplementation of phosphorus fertilizer and potassium fertilizer can also help cure the disease.

2. Pests: Common ones include "red spiders" and "aphids", etc. A commonly used pesticide is omethoate.
