The first formal irrigation should be prior to their leaf expansion. At this time, water is needed. The time can be determined according to different regions. It can promote the degree of germination and the growth of roots in this period of time from about mid April. However, a large amount of irrigation must not be conducted because they want to grow well, which is beyond their water absorption capacity. Absorb in, but cause water. This has a great influence on root development. If you don't master it well, it may rot.
The second formal irrigation is carried out before flowering, so this irrigation is also called pre flowering water, but it can not be too early. It should be carried out after the root starts to move. The purpose of this irrigation is very clear, that is to make roses have enough water during flowering and improve their quality. According to practical experience, if the water before flower is well poured, the flower can bloom 15% - 20% more. So not only time but also quantity should be controlled. But not every place has the condition to water at this time. Flower friends without this condition can choose to use water cellar to store water
This watering is basically in June. This is because the water will be used for flowering during the flowering period, while the other parts will lose a lot of water, so it is necessary to supplement water. In this way, we can guarantee the differentiation of flower buds next year, so that the flowers will grow better next year.
After each watering, we should cooperate with soil loosening, so that the water can enter the deeper part of the soil, rather than stay on the surface, which can prevent loss due to evaporation.
