pinch phlox and still lots of flowers?
This is the first full summer for our stand of Phlox Peppermint Twist. The actual flower is a bit unique but another appeal of this Phlox for us was it advertised reduced height. It is generally listed as around 18". Knowing this we planted two of them closer to the front of the garden in question. Well this year their first full growing season in the garden they are now over 40" tall (with tons of flowers) but have obscured several plants in the background. It isn't possible to relocate these plants but I am thinking that next...May? to pinch off a portion to reduce the final height. However I have not done this before with Phlox and I do not want to lose those flowers. Is May 'pinching' a successful technique for Phlox?
