Now that the pond tour is over, I decided to finally remove the invasive Oriental bittersweet (Celastrus orbiculatus) that I mistakenly planted a couple of years ago. I was planning to do it at some point, but Beth Botts’ post about invasive species recently banned in Chicago – including C. orbiculatus – got me moving. Well, that and all the bittersweet fruits that were forming!
I have tried to prune the C. orbiculatus (the bushy stuff on the left half of each of the two trellis panels) back a couple of times this year, but this only seemed to provoke greater growth. My native C. scandens (on the right half of each trellis panel) is growing really well, but is still sort of puny compared to the much older invasive.
A good hour of work with pruners, loppers, and a shovel (for the top foot of roots) later, it’s all gone and C. scandens has sole possession of the trellis. (Pretty impressive growth for something I planted only a year ago!) Since the old stuff is an invasive species and very woody, I skipped my lazy compost pile and put everything in a bag for municipal composting. That should be hot enough to kill all those berries that the C. orbiculatus was growing.
