Re-Weeding

The speed with which Bermuda grass clumps grow in our rose bed amazes me. It seems as if, in two or three weeks, the bed goes from clean to splotched with lush, dense, 12-inch-across crowns of this grass. The biggest crowns, moreover, invariably appear in the center of the bed or in among the canes of the roses. In either place, they are hard to reach without damaging the rose plants and getting scratched up.

Joined with the Bermuda grass are two weeds I haven't identified. One is bushy with leathery, dark-green leaves like jigsaw-puzzle pieces. It seems to come out readily. The other is our common low-growing weed, each of its round, dark-green leaves bearing in its center a dark brown spot. That one wants to snap off at ground level.
