The Little Shrub That Can't

Getting dark soil under my nails 
Rearranging the compost, 
Adding pesticide to try 
to keep it alive 
This shrub that is browning 
Dying and there isn't a reason
Even with my best efforts 
With all of my love and attention 
The leaves are still fading 
I want to save it 
But my heart is telling me no
Because nature isn't easy
To define, explain or control
As I watch its white flowers die 
My eyes water as I am left 
Wondering, 
Why?
