Culture Notes
Transplanting is moderately easy if plants are root-pruned and either balled and burlapped or potted.  White-Cedar likes high humidity and tolerates wet soils and some drought, but not salt exposure of any kind.  The foliage turns brownish in winter, especially on cultivars with colored foliage and on exposed sites open to the wind.  Many of the natural stands in the United States have been cut.  Some remain in isolated areas along rivers throughout the East. Some variegation is present on some branches.

Maintain adequate mulch area

Be sure to clear all turf away from beneath the branches and mulch to the drip line (the edge of the branches), especially on young trees, to reduce competition with turf and weeds.  This will allow roots to become well established and keep plants healthier.  Locate the tree properly, taking into account the ultimate size, since the tree looks best if it is not pruned to control size.  The tree can enhance any landscape with its delightful spring flush of foliage.  It can be the centerpiece of your landscape if properly located.
