When the new shoots grow, new inflorescences will appear at the top of the golden buds, so timely coring and pruning will help promote the golden buds to grow sturdily and bear more fruits. Generally, coring is carried out 2-3 times in its seedling stage to promote the growth of branches and control the plant height. Not only the newly cut seedlings need to be cored, but also the seedlings should be cored once when the height reaches about 6cm. When the branch grows to about 4cm, it needs to be cored again to promote the growth of the branch. One month after coring, the bud can blossom on the new branch.
