Will the plants actually survive our winters like a landscaping company promised?

Plant survival in Utah depends on hardiness zone, soil preparation, and maintenance. Salt Lake and Davis Counties sit in USDA Zone 6, where winter temperatures can drop below 0°F. A reputable landscaping company should specify plant materials rated for this zone or hardier. For example, lilacs, junipers, and many varieties of maple and spruce do well here. Problems arise when contractors install plants from warmer zones or fail to amend heavy clay soil before planting. Winter survival also depends on fall preparation: deep watering before the first freeze, proper mulching, and sometimes burlap wrapping for sensitive species. If a landscaper guarantees survival without addressing these steps, that’s a concern. Ask them about their plant warranty policy — many companies offer one-year guarantees provided you follow their care instructions. To boost survival odds, choose plants proven in local yards and follow the watering guidelines provided by the contractor. A solid company should walk you through this process in detail.
