Banyan Tree Roots
This complex series of roots runs down a steep hillside in San Diego's Balboa Park, the city's major park for museums and gardens.
Imported from Asia there are several monster size banyans in the park that are over 100 years old.
The banyan tree is one of the giants among trees.
To support its huge size the tree has the problem of drawing moisture from the roots to the top. The trunk of the tree must be strong. A tree cannot grow too tall and remain slender, or it would break. So a giant tree must be wider at the base to support the load above it. Arid if the branches are large and heavy, they could pull down the trunk to one side or another. The banyan tree is a giant tree that has solved these problems in an interesting way. The branches spread out in all directions all around the trunk. And even though the trunk is huge, it cannot support these branches. So thick roots grow from the underside of the branches directly to the ground.
When these roots take hold, they provide support and nourishment for the tree. They also develop into new trunks. The result is that the banyan tree grows more in circumference than in height. Eventually, "arcades" of these roots are formed, and a banyan tree may .have a circumference that reaches 450 metres.
Because the tree live long and are aso amaazing they also have religous meanings for Hindus and other eastern Asain religous groups.
