The grafted Osmunda japonica is not as good as the first year?

This is normal. Because there is some contradiction between flowering and long branches, the branches grow too long and it is difficult for long branches to bloom. In the first year of transplantation and grafting, because the root system and grafting are underdeveloped, it is difficult to grow long branches, so basically one branch and one flower. Solution: Prune the tree in spring and summer to avoid long branches and increase branches; If you don't prune, you can control the machine at an appropriate time, such as multi-effect frustration.
