In autumn, prepare shrubs for winter. You'll need mulch, wooden stakes, canvas and a shovel. If rain is scarce where you live, generously water shrubs when temperatures start dropping (but before it freezes). Use wind breaks to protect young or moderately resilient plants. To make one, frame the shrub with wooden stakes or PVC piping. Wrap the frame with a porous canvas like burlap. In the spring, when there's no risk of frost, remove the protective structure. If your shrub is weak, wrap it in burlap and tie it so the covering stays in place. Then bury it at least 6 inches (15.24 centimeters) deep, and cover with 8 inches to 10 inches (20.32 to 25.4 centimeters) of mulch. You can take it out of the ground once the cold season has passed.
