1、 Increase watering

The growth rate of Rosa roxburghii is relatively fast in spring, and the demand for water will slowly increase. It needs to be watered once or twice a week in early spring and twice or three times a week in late spring. Because the temperature in late spring is relatively high and the water evaporates quickly, it is necessary to increase the amount of watering so as not to affect its growth. When watering, first observe its state. Watering is required only after the soil is completely dry. If the soil is wet, watering is not required for the time being

2、 Controlled fertilization

After entering the growth period in spring, topdressing is required once or twice a month. The fertilizer seed needs to use the diluted fertilizer cake water. Try not to use the fertilizer seed with strong fertilizer effect. Because it has just passed the dormancy period and its ability to absorb nutrients has not been fully restored, the fertilizer with too strong fertilizer effect will cause fertilizer damage. By late spring, its growth state has been stable and will blossom soon. It needs to use phosphorus and potassium fertilizer specifically. Phosphorus and potassium fertilizer can promote plant flowering

3、 Ensure stability

If the temperature is higher than 15 degrees in spring, it will not grow stably in the outdoor environment, so it is often required to maintain in an unstable temperature. It can be maintained in a sunny place at ordinary times, and sufficient sunshine can also increase the temperature
