(Winter Care for Zone 5)
During the cold winter months, add 2-3 inches of mulch around the plant to protect the roots from harsh temperatures. Pine straw, leaves, or pine bark mulch are all good organic materials that may be used in the garden. Since climates can vary, even among specific regions, please contact your preferred local garden center for recommendations.
