Relative Something

It is the season for easy sighting of the invasive Common Buckthorn which we regularly seek out for elimination from our woods. The leaves of Buckthorn hold a deep green color longer than most other undergrowth in the fall. Now is the time when I can spot what was previously obscured by other summer growth in the woods and venture off-trail to cut back any progress made by the pernicious invader since last year.

The small sprouts that pop up from seeds dropped by birds are easy to pull by hand. New sprouts that emerge out of a root structure that was already in existence don’t pull as well. If I bring a shovel with me on these missions, a lot of those can be dug up. Anything that has made it to “tree” size presents a bigger challenge.

I have decided on a process that I call my method of madness, partly as a result of a handsaw being all I was carrying way back when I first started cutting Buckthorn on our property. I cut off the trees at a height of 3 or 4 feet so the stump will be noticeable the next time I pass by, knowing there will be subsequent growth since I don’t apply an herbicide to the cut.

This process wouldn’t be practical if I wasn’t constantly walking through these woods and following up each year on the re-sprouting stumps. After a while, new sprouts will stop showing up. Here are before and after images of one example of my madness:

This year I have also removed a section of bark on some of the stumps to see if that will prevent new sprouts above the break.

I found an interesting video from the University of Minnesota Extension that reveals how Buckthorn has become a winter haven for soybean aphids. An added incentive for farmers to pay attention to the invasive growing beside their crop fields.

Boggles my mind that people figure out stuff like this. Who noticed the aphids were going to the Buckthorn and laying eggs that survive the winter?

Seems like madness to me.
