What am I supposed to do here?

Hint 1 of 13:

You are in the maze garden of your house, except the year is 1808.  
Capability is busy planting the family tree.  Don't bother him.  He has
finished planting the hedge for the garden maze.  Ten or so more years, 
and it will be quite a sight.

Hint 2 of 13:

Isn't there a place in the maze you would rather not have a hedge?

Hint 3 of 13:

Have you climbed the family tree in the present day?
