How to grow roses without insects?

Rose, with its diverse colors and fragrant aroma, is deeply loved by flower lovers. However, rose is also called "medicine jar" because it is susceptible to diseases and pests. In fact, as long as we do a good job of management in daily maintenance, we can keep the rose in a healthy growth state and avoid the trouble of diseases and pests. So how can we grow roses without them being infested with insects?

1. Ventilate frequently

Poor ventilation is the main cause of rose disease and insect infestation. When maintaining a closed balcony, ventilation equipment should be added, such as installing a ventilation fan or using an electric fan to increase air circulation. Good ventilation helps reduce the occurrence of pests and diseases and keep roses healthy.

2. Fertilize frequently

Roses grow quickly and bloom in large quantities, so they need adequate fertilizer support. During the growing season, a balanced fertilizer of nitrogen, phosphorus and potassium should be used to promote the growth of branches and leaves and the development of the root system. When the rose is about to bloom, add high-phosphorus fertilizer, such as Huaduoduo No. 2 or potassium dihydrogen phosphate, to promote flower bud differentiation and the fullness of the flowers. Fertilize regularly, 2-3 times a month, using the principle of applying thin fertilizers frequently to ensure that the roses have sufficient nutrients and grow vigorously.

3. Spray pesticides frequently

Roses are susceptible to diseases and pests, especially in continuous rainy weather. Check the weather forecast regularly and use fungicides and insecticides in advance for prevention when encountering consecutive rainy days. Use fungicides such as carbendazim to prevent diseases, and insecticides such as avermitilis and imidacloprid to prevent pests. In clear weather, spray insecticides and fungicides once every half a month to ensure that roses are free from diseases and pests throughout the year.

In summary, the maintenance of roses is not difficult. The key lies in doing a good job of daily management. By frequently ventilating, fertilizing and spraying pesticides, you can effectively prevent the occurrence of diseases and pests and maintain the healthy growth of roses. Once signs of disease or pest are found in roses, timely measures should be taken to prevent the disease from worsening. Timely prevention and treatment.
