Mekiri is a bonsai technique of trimming new buds to balance the strength of bud growth in pine trees, such as kuromatsu (Japanese Black Pine). Mekiri is usually done in summer, after the spring growth has hardened off. By removing the strong buds, mekiri allows the weaker buds to develop and create a more compact and dense foliage. Mekiri also helps to reduce the needle length and improve the ramification of the branches. Mekiri is not a uniform process and varies depending on the species of pine, the health of the tree, and the desired style. Mekiri should be done with care and precision, using sharp scissors or tweezers. Mekiri is an essential technique for maintaining the health and beauty of pine bonsai.
