Why is the company planting in this heat or cold?

With proper practices, planting outside of “ideal” spring or fall windows can be perfectly safe. In summer, Utah crews usually plant early in the morning, water deeply at installation, and apply mulch to protect roots from heat stress. Heat-tolerant and drought-adapted species can establish well even in warm months if irrigation is managed carefully. In late fall, many deciduous trees and shrubs actually transplant best while dormant, since they can focus energy on root growth before spring. Cold-weather planting works as long as the soil isn’t frozen solid. The key factors are species selection for Zone 6, proper soil preparation, and a detailed watering schedule to support establishment. Ask your contractor for their watering plan and warranty terms for off-season installs—reputable companies in Salt Lake and Davis Counties will stand behind the plants they install, regardless of season, if they follow best practices.
