Everyone knows that plants die if winter temperatures are too frigid for them to endure. But severe weather can pose a threat even to hardy plants. An early-season burst of bitter cold can shatter the cells of woody plants that haven’t yet hardened off. Later in the season, those same plants could march through a similar cold snap in stride. Deeper into winter, cold, dry winds can draw the life from conifers or broad-leaved evergreens. Even warm spells can be perilous. High temperatures can evaporate the last reserves of moisture from the transpiring leaves of evergreens whose roots, locked in frozen ground, are unable to draw replenishing moisture from the soil. How can you save your plants? Here are some useful tips.
- Protect tender plants with water, mulch and shelter.
- Burlap works well for shrubs or small trees.
- Protect perennials with a simple cover.
- Build a winter home for larger plants.
