I’ve been pulling Italian thistle (an invasive monster) since mid-November. It’s now mid-March and we still have very young plants coming in (see pic, gloved finger for scale). Today, I decided to call it the “third wave” but I have no idea if it comes in waves at all, or just constantly. Or if it comes in waves, how many can we expect? Five? Ten?
All I know is that it will continue to come in for quite some time, and I need to keep an eye out for these little guys probably well into May. Part of the reason may be the very wet winter we are having, as none of the thistle is bolting yet but the plants, in some cases, are becoming very large. This presages a massive stalk, which will mean more bulk to deal with when we need to begin bagging the thistle and carrying it out.
Also, the rain is preventing me from using 30 percent vinegar to battle big patches, since I need sun to follow spraying, not rain that will wash it off. So far we haven’t many stretches of dry weather.
Sorry to be a Debby Downer, but these are just some of the challenges we face when attempting to control invasive thistle on these lands.
