This has been an outrageous growing season, with lots of rain and warm temperatures. Some plants just get carried away! So I say whack it back! Late-blooming plants need a shearing or they will topple over before they get their mojo going (full bloom).
I recommend cutting back at least a third of the vegetative growth for the following specimens:
- garden phlox
- Russian sage
- sedum Autumn Joy
- perennial sunflowers
- spireas- which promotes new red growth tips on Magic Carpet, Double Play or Gold Flame
- flowering shrubs that have already bloomed
