Last year these beds around SE 8th and Division Pl. were in bad shape suffering from a high density of aggressive weeds including Canada Thistle. They were left in place through seed stage. This year they naturally returned. A maintenance crew came through at some point mid to late summer and cleaned this series of three beds mysteriously cutting the culms of the Flowering Reed Grass down by half as well, one of this plants most ornamental features. I don’t know if they manually stripped away the weed tops at that time or if they had treated them with herbicide. Treatment to be effective must be made to Canada Thistle after the flower buds have formed. Time will tell.
