3. Moisture requirements

Roses are drought-tolerant, but not waterlogged. Water the soil after it dries. Potted plants should not be watered when the temperature is lower than 0℃, and should be watered at noon when they are moved indoors for wintering maintenance.

4. Temperature requirements

The suitable growth temperature of roses is 65438 02 ~ 28℃. Roses can differentiate flower buds in an environment above 7℃. The longer the high temperature time after bud pregnancy, the earlier the flowering. The flowering period is not suitable for maintenance in a hot environment. When the temperature is higher than 35℃ in summer, plants will hibernate and should be cooled appropriately.

Rose is relatively cold-tolerant, and most varieties can tolerate the low temperature of-15℃. When the temperature is too low in winter, plants will go into dormancy. In the northern region, there is no need to keep warm, and potted plants should be put in a sunny environment at 20℃ for the winter.
