Do I need to wrap or protect landscaping in winter?

Some of it, yes. New trees benefit from trunk wrap from late fall to early spring to reduce sunscald and frost cracking, especially on southwest exposures. Evergreens in exposed sites can suffer windburn; burlap wind screens and antidesiccant sprays (used correctly) help. Apply 2–3 inches of mulch over beds to insulate roots, but keep it a few inches away from trunks to prevent rot. During dry spells above 40°F, deep-water evergreens and first-year plantings; winter drought is a common cause of spring dieback in Utah. Mark vulnerable plants for snow-load protection and use stakes or twine to support multi-stem shrubs. Ask your contractor to tag which plants need what: wrap, wind screen, extra mulch, or winter watering. A one-page winter checklist with timing and methods keeps care simple and helps everything leaf out stronger in spring.
