How do you bring evergreen bushes back to life?
Keeping the plant well-watered as winter approaches helps it store sufficient water to carry it through the cold months. Adding a thick layer of mulch at the plant's root zone also helps conserve soil moisture. You could also spray the plant with an anti-desiccation solution, available pre-diluted at garden centers.
