Q.Trimming Back Impatiens
I have 12 window boxes of impatiens on my deck, planted late April, and they are quite high and leggy. . . beginning to fall over. Can I cut them back to shorter stems, and will they regenerate and continue to bloom? I realize cutting back will remove all blooms, but its still early summer. If they do regenerate, about how long should it take to see new blooms?

Too much fertilizer can cause leggy plants and reduced flowering. Pinch them back to 6 inches and they should regrow as bushier plants. Leggy plants are also fixed by trimming off the plant so that it looks more like a bush shape.
