Wow. What a hiatus. Longest one ever. I'll just reference this and move on.
When we bought our house, it was seriously overgrown. European Buckthorn was the most prevalent species. I pulled it out, cut it down and chopped it up. There was one buckthorn near the property line that was actually quite nice as invasive species go. It was tall and straight, adopting a tree-like form, rather than the bush form. I named him Ted.
In my research of buckthorn, one warning that was frequently expressed was to NOT cut it off at the ground. Buckthorn freely suckers and cutting it off at the ground would just make the issue worse as the plant would turn into a messy bush. While I could appreciate Ted as a tree, he was still a buckthorn, so two years ago I cut him off at five feet and decided that I would wait until out tree guy came to visit. Then Ted would get cut off at the ground and chipped out. So last spring, we had our tree guy come out to chip some stumps. And somehow we missed Ted.
Two weeks ago, we decided to have our tree guy out again to finish off the last of the scrub. My wife and I went over what needed to be done. She went over it with the tree guy again. And we missed Ted again. At this point, I've dubbed Ted the Ninja Buckthorn. He hides in plain sight.
But no more. As part of the honeysuckle clean up, he's succumbed to the shovel. He's been dug out and Ted is now hiding in the backyard, propped against a tree, waiting for the fire ring. We'll see how long it takes for me to find him to burn.
