It's a case of wrong plant, wrong place. In my own defense, I must explain that this Forsythia was here when I bought the house. It was nowhere near as large then. I have thinned it repeatedly, removing the old, thick stems at ground level. I cut it back again this Spring. Then, the August deluge came. The sump pump ejector tube is behind this plant. When it overflowed, the excess water got sucked up by the Forsythia. All that extra water resulted in this extra growth. The question is, do I cut it back now, sacrificing next year's blooms? Do I leave it to thwack against the house all Winter? Or do I try to remove it now? I don't like any of these options. In any event, this plant's days are numbered.
