Yuyemei likes humid environment, but it can stand drought.
In the first year of planting, special attention should be paid to water management. In summer, sufficient water should be supplied to the plants in time to prevent the death of Ulmus pumila due to water shortage.
After entering the normal management and maintenance, pay attention to watering the three waters, which refer to the green water in early spring, the growth water in mid spring and the frozen water in early winter.
Among them, the green water in early spring has a great influence on the flowering quality and one-year growth of Prunus triloba. This watering can not only prevent freezing injury in early spring, but also provide water for plant growth in time. Therefore, the water in early spring should be early rather than late, generally in early March. If it's late, it can't play the role of cold prevention and antifreeze. When watering, pay attention to fully watering.
In late April, we need to water again, because there is more wind and less rain in spring, and this watering can meet the needs of plant growth.
Yuyemei likes fertilizer, so when planting, you can use a few spades of rotten cattle and horse manure as the base fertilizer.
In the second year, after the flowering period in spring, when the flower bud differentiates in summer and before the winter, it can be applied once respectively.
Yuyemei consumes a lot of nutrients after the early spring flowering. At this time, topdressing is very conducive to the growth of the plant, which can make the plant grow vigorously and flourish.
From June to September in summer is the flower bud differentiation period of Prunus triloba. At this time, some p and K fertilizer should be applied appropriately, which is conducive to flower bud differentiation and full lignification of new shoots in the same year.
Before winter, topdressing should be carried out in combination with freezing water. Applying some ring fertilizers can effectively improve the ground temperature, enhance the permeability of the soil, and help to provide sufficient nutrients at the flowering stage of Prunus triloba in the early spring of the next year. Therefore, this fertilization should be shallow rather than deep. After fertilization, it should be watered in time and ring fertilization can be adopted.
