I am trying to recreate terrain from Core Academy but draw distance is not enough

[uruskan]

So I am doing the core certification 2, I am complete beginner to game development.
I understood terrain tools, foliage etc. throughly but I have a problem.
I am trying to create a mountain view, and I accomplished it to a point.
My problem is I can't see trees far away from my viewing point and there seem to be no option for that.
Here is some pictures:

There are actually trees far away too but they are just not rendering.
What can I do?

I found the solution and I am sharing here to it might help other new people like me.

So as long as I understand, there is no draw distance option for Foliage so we have to add our trees with object generator as individual objects.

You can acces object generator from Window menu.

Here is the result with object generator.
