Why do I see so many plants "balled" up when I walk or drive places? Plants like Philadelphus, Weigela, Physocarpus, Viaburnum bodnantense, etc. They turn into huge balls of foliage with little or no flowers. I actually find it easier removing 1 in 4 or however many it should be from the base of the plant, rather than hedgecutting or shearing it. I'd never cut a Wisteria with a hedgecutter, so why a Philadelphus. Grinds my gears.
