Hi gardener friends. I have a Dahlia question. I hav a bunch of big dahlia plants that are blooming steadily, but some of the taller (TALL!) stalks were knocked over in a rainstorm. If I cut the plants back, will they continue to grow? Get bushier? I want them bushier and less stalk-like, and we have a month of summer left here in Oregon, so is this enough time to cut and regrow? Am I making any sense at all? THANKS!
