Invasives On Holiday

Day 60: Ah, yes. Revised somewhat from last year's effort, I give you my new and improved version of this traditional holiday carol:

The holly and the ivy,
Both as invasives cursed!
Of all the shrubbery in our woods,
These two are just the worst.
Oh, the rising of the sap
And spreading of the seeds!
A little dash of 2, 4, 5-T
Is what this problem needs
(Is what this problem needs)!

You may of course substitute "Agent Orange" for "2, 4, 5-T" if you can't get the scansion right. Or use your own choice of herbicide, although it may not be quite as effective in the field or lyrically.
