The time of watering rose is not too strict. Except in winter, it's better not to water it at noon. The roots can't bear to adapt. When the sun just came out and the sun set, it was suitable to apply water in these two periods, and had little effect on the roots.
Special attention should be paid to the watering method. Do not pour water from the top, especially at the flowering time. Do not make the leaves and the flower center part accumulate water, or the flowers and leaves will be burned when the sun shines.
In order to ensure the growth, the water volume also needs attention. Add appropriate water to ensure that the root can be fully absorbed. If the water volume is too small, half of the water is likely to appear, and the growth will be dry and water deficient. Pay attention to control the water volume. If the water volume is added too much, it will lead to water accumulation, the root is difficult to breathe normally, and it may be anoxic and rotten.
There is no fixed time limit for the frequency of watering, and the water demand will be different under different climate conditions. Generally, watering can be done when the basin soil surface turns white. In spring, the humidity is high and the temperature is low. The secondary water is given about 15 days. In summer, the humidity is small and the watering cycle is short. The secondary water can be given about 10 days.
