My Planters

Each year when the summer is nigh
I drag out my planters and buy
     Some flowers to plant
     But somehow I can't
Make them grow, though I really do try.

I gently tamp down all the soil.
With watering, I am quite loyal.
     While others' plants thrive
     Mine are barely alive;
All my efforts Ma Nature does foil.

Still, just planted they look pretty good.
If they lasted, the way that they should,
     I'd be shocked as they come
     'Cause my never-green thumb
Would have done what I'd hoped that it would.
