In Bonsai the two P's are very important for a healthy Bonsai.
1.P atience
2.P erceiverance
It will take 3 to 4 years atleast for a plant brought from a nursery
to become a good Bonsai.
The will power to maintain and see and check the tree in equal
intervels is quite important.

Matured look for a bonsai is important rather than the age of the
bonsai tree.
