When the bonsai received a form, listed or not, it continues to grow, slowly of course. Its development must then be controlled by a specific size called "maintenance size" which consists of folding the newly pushed leaves to maintain the shape chosen at the beginning. The pinching, usually manual and which occurs on newly hatched ends, is part of the same concern for densification of the branches by thwarting its extension.
- Scissors with buds
- Normal scissors
- Leaf cutter
1. The maintenance size, if it does not require sturdy tools such as tweezers or wire clamps however requires the use of perfectly sharp tools, whether normal scissors or small leaf cutter.
2. The drawing to the right is an illustration of a classic size (Hôkidachi) with an indication of what should be kept in the tree for the evoked form and what should be removed from it. One must always have in mind the shape one has chosen to give to one's bonsai when performing a maintenance size.
3. In addition to the maintenance size of a bonsai tree, the pinching (manual or chisel) of the new buds contributes to the slowing of the extension of the extremities, in favor of densification of the foliage. This technique allows branching of the pinched branch and nanification of new leaves. It increases the circulation of the sap by the calls that creates the branch which has undergone it.
4. The beautifully colored maple tree has extremely thin stems and is therefore more easily cut with scissors.
5. On the other hand, the chisel is more practical for cutting leaves that have a greater thickness.
6.It is important to clean the floor at the foot of the bonsai after a size, be it training or maintenance. Indeed cutting waste would quickly become a parasitic focus favorable cryptogam, powered by watering.
7. The shape of this bonsai is still discernible despite the growth of its foliage. The size of maintenance will be to make this form perfectly defined and find the beauty that results.
8. Scissor work is done to first cut the stems and leaves that clearly exceed the shape.
9. The second part of the work is done by scissors because it is now a question of refining the size and especially not to create unsightly holes.
10. The size completed and the floor cleaned, this Chinese elm has found all the serenity that emerges from its simple and regular shape, elegant as a mushroom.
11. The still tender shoots of spruces are pinched between one-third and two-thirds. By cons, yew, larch or juniper, it is the bud that must be pinched.
12. For conifers, pinching only occurs once a year, around April. it is done with the nails. Do not use scissors because the tips of the remaining needles will be cut off and yellow a few weeks later.
13. The drawing on the right shows the pinching places of a Chinese juniper. it must be pinched very short.
14. Contrary to conifers, the juniper pinches throughout its active vegetation period, ie from April to October.
15. The size of this bonsai, a bamboo, allows to develop in this filiform tree, a network of small leaves that will dress it, without being concealed its slender character.
