1, shading and shading

The light in summer is very strong, especially the scorching sun in the midsummer afternoon. Try not to expose roses to the sun, otherwise it will easily lead to dehydration and scorching of plants. However, Chinese rose can receive mild direct sunlight in the morning and evening in summer, and it can be exposed to light for about 3-5 hours every day, which can make the plants grow and bloom better.

2. The suitable temperature for cooling and moisturizing rose growth is 15 ~ 26℃, and the summer temperature is generally above 32℃. When the high temperature comes, it is necessary to shade and cool down in time, move the rose to a cool and ventilated place, and often spray water on the plants to keep them moist.

Dilute fertilizer solution can be applied once every half month, and professional flower fertilizer can be purchased, mainly nitrogen, phosphorus and potassium compound fertilizer. Thin bean cake fertilizer and chicken manure fertilizer can also be applied to meet the demand for nutrients during the growth of Chinese rose.

5, pest control

In high temperature season, rose is more prone to pests and diseases. In hot weather, it is easy to spray carbendazim and potassium permanganate on or around Chinese rose plants to kill bacteria and insects.
