Answer: Sudden wilting of the entire bush often indicates an unfortunate event such as accidental herbicide contact, a broken stem, or severe root disturbance, possibly by a vole. Inspect the plant carefully for signs of trauma. If there is root damage, you may be able to salvage it by digging it up and replanting it or by replacing any missing soil and taking care to keep the soil evenly moist. Trim it back next spring to compensate for the root damage.
