Plant Fire Chief® Globe Arborvitae in well-drained soil with full sun to partial shade. Space plants 3-4 feet apart. Water regularly, especially during dry spells, to keep the soil consistently moist but not waterlogged. Fertilize in early spring with a balanced, slow-release fertilizer. Prune lightly in late winter or early spring to maintain shape. Protect from harsh winter winds and heavy snow by wrapping with burlap if necessary.
