First, if it is the early stage of the pest disaster, it can be cleared manually. Wear gloves directly and crush aphids with your hands. You can also use scissors to cut off the branches and leaves of individual aphids and bury them in the soil.

Second, when a large number of insects appear, we should distinguish what they are, usually aphids, borers, scale insects and so on. When it is not very serious, you can use soda and cleaning agent to prepare water solution. After dilution, spray the insect-trapping part, and finally rinse it with clear water. In addition, you can also try spraying with washing water, soapy water, tobacco leaf water and pepper water. In severe cases, 2000 times of 10% imidacloprid wettable powder should be sprayed.

Matters needing attention in rose planting and maintenance

First, planting density is very important. It shouldn't be too big or too small. Too dense will block the sun, and when you grow up, you will be squeezed and compete for nutrients and fertilizers. If you are too alienated, it will also lead to water shortage and insufficient fertilizer.

Second, pay attention to the depth of planting and watering. Depth is also a part that cannot be ignored. It should be based on the original soil traces of plants. If the depth is appropriate, too deep or too shallow will affect its growth retardation and growth. For watering, it is not advisable to overdo it. As long as it is suitable, water it 1 time for four days in June. The leaves can be sprayed once every two days, which is more conducive to the growth and budding of Chinese roses.

Third, before planting fragrant roses, we must apply base fertilizer, which can be made of cow and pig manure or burnt with rotten branches. Then put organic fertilizer in loose soil. Fertilizing with 0.2% urea every 5 or 6 days can promote the germination of new buds; Then spray 0.2% potassium dihydrogen phosphate every 5 or 6 days to promote the growth of flower buds. If not, you can choose fermentation nutrient solution, and use it every 7 days 1 time.

4. Pruning is essential for every plant, especially for plants with large vegetation, pruning should be carried out to cut off dead branches, fallen leaves, branches and excessively long branches. Each plant needs to keep 5 strong branches. This can also ensure the survival rate of plants.

Sunlight is another fertilizer for Chinese rose. If the sunshine is insufficient, it will also affect the development of Chinese rose flowers and lead to insufficient nutrient absorption. Therefore, if the land where the fragrant rose is planted, it should be planted in a sunny place.
