Second, watering: Osmanthus fragrans should be watered less before the new branches grow, as long as the soil is slightly wet. Too much watering will not only affect the growth of new roots, but also make them rot. Water should be reduced in rainy season and increased in hot summer.
3. Fertilization: Fertilize frequently during the growth period, and the amount of fertilization should be less. After germination, applying pancake fertilizer every half month can help new branches grow better; In May, in order to make the branches more mature, phosphorus and potassium fertilizer can be applied once every 10 day.

De-sprouting and bud wiping is a method to wipe off new buds before they are lignified at the beginning of germination or germination. This work in time can save a lot of organic nutrients and promote the rapid and healthy development of retained branches.
In addition to germination and bud wiping, the focus is on the roots and necks of young trees near the ground, which should be carried out many times a year, especially in time before the spring, summer and autumn shoots flourish. These new buds, which germinate from adventitious buds and latent buds, have strong vitality, fast germination speed, slightly delayed treatment time, and many tufted branches will appear at the base.
What's more, some long branches directly compete with the trunk, disrupting the original tree shape. Due to various reasons, germination and smearing can not be carried out in time, and the tillers for germination have grown up. When pruning, all of them should be removed from the base, leaving no living piles, otherwise the sprouting tillers will be cut more and more.
