How to manage grafted seedlings?

Generally, grafted seedlings can heal and survive in 1.5 months after grafting. When the scion bud grows to about 2 cm, the restraint should be lifted, otherwise the normal growth of seedlings will be affected. If you pile up soil afterwards, you should pay attention to timely inspection, and remove the pile after the succession to avoid the buds from turning yellow because you can't see the sun. If the pile of soil is too thick, it is best to remove the pile twice to avoid the buds being burned by the sun. When the scion grows new buds, the rootstock above the joint should be cut off to facilitate the growth of the scion. When the grafted seedlings grow to a height of about 20 cm, they need to be supported to prevent them from being blown off by strong winds. The sprouting strips on the rootstock should be erased in time to avoid consuming nutrients and affecting the growth of grafted seedlings.
