At this time, it is also the peak season for Chinese plum growth, and the bud grafting survival rate is relatively high.

3. Select buds. Generally, bud grafting of flowers and trees is to select the new buds on the growing branches of the current year, while bud grafting of Chinese plum should select the hidden buds on the growing branches of the first year. The operation method is the same as that of other "D" grafting methods. After grafting survives for 20 days, the hidden buds begin to sprout. When 2-3 leaves grow, remove the binding rope, strengthen maintenance, and be careful to be blown by the wind. Before the first ten days of June, the grafted ones can grow to 50 cm to 65 cm in the current year, some can bloom in winter, most of the grafted ones after the middle of June can germinate in the current year, grow to 15-30 cm, after a few buds survive, they can germinate in the spring of the next year, but they grow very vigorously. As long as they are properly protected, they can grow to about 1 meter in the second year, and they can bloom in large quantities in winter. The grafting of Chimonanthus praecox should use the hidden bud on the growth branch of the first year, which is the key to the survival of bud grafting of Chimonanthus praecox.
