Question

Why do the leaves of the trees appear as layers? note down the guses?

Answer 1

As trees mature, they often growth their branches into horizontal layers. These branches may have initially been fairly near vertical, but the weight of the leaves and wood and buds and especially the seeds or fruit will gradually pull the branch down, and it will only firm up and toughen its wood when it reaches a horizontal reach that it can manage, which gives it a wider catch of light. Some tree species try to reach too far, and wind and storms break off the over-reached parts. Pecan trees are famous for this. The broken off branch sprouts new secondary limbs. Old pecan trees are famous for shedding whole branches.

The layered branching structure is one of the objectives of Bonsai masters, as a way too add apparent age to a small bonsai tree. Layered branching doesn’t usually happen in a natural tree until it is fairly advanced in age.
