One of the jobs that I have taken on this summer is keeping the usable space we have reclaimed, from the blackberry vines and Scotch Broom, clear.
Buck has invested a lot of blood, sweat and tears into clearing some major mounds of blackberry and I have been keeping them in check, starving the roots by continually harassing the sprouts with my boot heel and the mower. It seems to be working. They send up fewer and skinnier sprouts each time.
Another ongoing strategy I have adopted is that when I am walking the property for any reason I pull as many small Scotch Broom as I can with my gloved hands. My currant record is 150 in an hour. I admit some of them were barely bigger than a pencil, but hey, they would have just become bigger and bigger, throwing their seed far and wide.
I mowed around the upper burn pile for safety but in the process found myself imagining what it would look like from an airplane and found myself mowing what amounts to a giant spiral crop circle.
