Long-suffering readers of this blog are probably saying to themselves, “Oh no, here he goes again!” And that is perfectly understandable, as during invasive species removal season (essentially the first six months of the year), I’m obsessed with it. I admitted this nearly four years ago, and the disease sadly continues unabated. So here we go again. Buckle up, buttercup.
For years now, the primary method we’ve been using to fight invasive species (first Scotch Broom and Yellow Star Thistle, now Italian Thistle) is pulling. Early in the season we can just pull and drop the weeds, as they are not in danger of going to seed. But later we pull it, bag it, and carry it out. After years of doing this, and largely being successful against the Yellow Star Thistle (which has yet to be spotted on either the Overlook or Montini properties this season!), I’ve become discouraged at the progress against Italian Thistle.
Unlike Yellow Star Thistle, which grows only in open meadows, Italian Thistle will grow anywhere. It’s rampant on the Montini Preserve, although we may still have a chance at reducing it on the Overlook. For the last couple years I’ve focused on pushing it back from the Overlook Trail to prevent it’s spread. For some sections of trail I’ve also been able to completely eradicate it this season. I’ve noticed some progress from last year along the trail, but this must be compared to areas where it has now spread, mostly into areas where the Yellow Star Thistle had been cleared.
Although pulling remains the only sure way to reduce the extent of thistle, we’re getting close to the time when the seed is produced (some already has) and at my current rate of pulling there are going to be a lot of areas that I won’t be able to address. So I’ve decided to take a chance at cutting it. Cutting is typically not advised, as the thistle can still produce flowers and seeds after being cut, but I want to try it this season hoping that I’m late enough in the season that it doesn’t have time to regenerate — although the recent rains likely aren’t helping.
So if you see me out there channeling my inner Jamie Lannister, that’s why. I can cut a lot faster than I can pull, and there is still so much out there. We shall see if it’s effective or not, and make adjustments as the evidence indicates.
It’s all we can do.
