The Japanese word "Furuhatori" means cutting old leaves. It is a technique used in bonsai to improve the health and appearance of the trees. By removing old leaves from summer to autumn, the bonsai artist can provide sufficient sunlight and ventilation to the roots of the branches, which are essential for photosynthesis and respiration. Furuhatori also helps to reduce pests and diseases that may affect the foliage. Furuhatori is usually done on deciduous trees, such as maples, elms, and hornbeams, but can also be applied to some evergreens, such as pines and junipers.
