Khan,
You have rightly pointed out that small leaves are essential to maintain the right proportion vis-a-vis the stem and branches of a bonsai.
I would like to share my views and experience with you on how to reduce leaf size:
1)
Defoliation: this is a process of removing the foliage/leaves of the tree.
For example after the spring growth when the new leaves turn dark green, cut the apex of the branch keeping only 2 three nodes/leaves. Let the leaves mature fully. About a month or two later, cut all all the leaves leaving only the leaf stock. The second flush of leaves/shoots, that will appear, will be comparatively smaller than the first growth.
Let this growth mature for a few more months, and again repeat the process of defoliation in the months of Aug/Sep. The 3rd set of leaves will be more smaller compared to the 2nd flush of shoots.
This will reduce the leaf size considerably, and you will get a very good branch ramification as well. I have tried and got good results, with fwg species:
- Ficus rumphii
- Ficus retusa
- Ficus religiosa (Pipul)
- Bougainvillea
- Arjuna indica
- Streblus asper, etc
2)
CAUTION: The defoliation should be carried out only on healthy trees! If the tree is not vigorous, defoliation should be avoided.
If on the other hand the tree is healthy, defoliation can be carried out once or twice a year, depending upon the speicies. To frequent defoliation on some species can be disastrous and fatal.
3)
Fertilization: Balanced fertilizaion is very essential to growing a well proportioned bonsai. A nitrogen based fertilizer will most likely produce big green leaves. While this helps to create vigorous foliage in the spring/summer season, a potash and phosphorous based fertilizer during late summer / autumn will help to check the size of the leaves.
4)
Sunlight: Sufficient sunlight is essential to check the leaf size. I personally prefer growing trees under full sun. However, care should be taken for Mame and Shohin size bonsai, which would require additional watering, compared to a larger bonsai, to keep the soil moist.
5)
Regular pruning: It is important to check the growth of the tree at regular intervals by constant pruning.
It helps to thicken the stem and branches and to some extent helps in leaf size reduction. As a bonus, you will get very good branch ramification.
I hope this info would be of some help to the members.
