All cultivars of panicle hydrangeas are well-adapted to soil types in the Upper Midwest, making them easy-to-care-for landscape features. Panicle hydrangeas bloom best in full or half-day sun, unlike the round-flowered hydrangeas that thrive better in shade. Pruning panicle hydrangeas, like most shrubs, is better accomplished in early spring before they leaf out, instead of fall. Because the flower clusters tend to hang on all winter, spring pruning also cleans up and removes the spent flowers. I’ve read you’re not supposed to eat green potatoes, but how do we prevent it from happening in the future?
