Doctor of Nature

The signs and symptoms of a season,
Look to the vegetation on your garden,
A plethora of tests for a diagnosis!
The trees alone is a great indicator,
For their status will determine the season.
There are no leaves on the trees,
Not a single trace,
The branches without their best friends,
Longing for their return,
That indicates winter.
The leaves are erupting from the branches,
Claiming the space as their territory,
That indicates spring.
All leaves are present in the trees,
Their color providing a contrast
To the grayish barks,
That indicates summer.
The color of the leaves become assorted,
Eventually becoming a uniform brown,
Losing their grip on the branches,
That indicates autumn.
You are the doctor of nature,
Carefully inspecting the clues,
For the world relies on you.
