Bugger. I do have a lot of those big, squeaky thistles. Keep
spraying them
and the pattersons, and am making inroads, but never quite get on
top of
them.

Doing both of these at the rosette stage (ie now) is the best time to
knock them off. My husband has got rid of nealry all the thistles on
our place by doing it at this time of year but it took a good 5 or so
years but we proably have more land than you.
