My Class II Invasive "ears" grow on the septic side, where they dig in next to the a/c unit. I don't always go over to that side of the yard, except to mow the septic area and cut back anything that attempts to grow around the a/c or creeps under the house. I was quite surprised that they had gotten so huge and out of hand. I mean, it really hadn't been THAT long since I mowed. Pretty much I have to mow every 4 days .it's rainy season, after all. But, that is a problem with invasives. They grow so unbounded and quickly that it can make your head spin.
So, I grabbed my trusty shovel and dug out the culprits and have them hanging upside down, roots to be fried by the sun until no longer viable. That is unless I find someone with a nice burn pit.
I suppose they are once again eradicated until next time they pop up. Curse you invasives!
