1. Soil: Chinese rose is suitable to grow in acidic soil with rich humus, and alkaline soil will make it grow poorly. At the same time, the soil should be changed every year to help it bloom. It can be prepared by mixing garden soil, rotten leaf soil and rice husk ash in the ratio of 5:3:2

2. Light: rose flowers need sufficient light during the growth period, at least 6 hours a day. Generally, it is better to bask in the sun in the morning, and the sun is too strong at noon, which has a burning effect on its leaves

3. Watering: when the soil is dry and white, you can water the roses. Generally, it can be watered once a day in spring and autumn, once in the morning and evening in summer, and less in winter dormancy

4. Fertilization: during the growth period of rose, light fertilizer and water should be applied every ten days. Dilute as much as possible before fertilization to avoid damaging the roots. Organic fertilizer can be applied once before winter to help it survive the winter safely. Do not apply fertilizer in winter
