Culture Notes
The compact columnar arborvitae thrives in full sun in fertile, well-drained soil with summer watering for the first few seasons. Do not allow a newly planted cedar to dry out completely as it may drop foliage and become bare and unattractive. A soaker hose and mulch are ideal for a new cedar hedge. Once established, cedars are drought tolerant. Set hedge plants 18 to 24 inches from center to center, depending on how large the plants are initially. When planting "b&b" (balled and burlapped) cedars, be sure to cut the burlap and twine away from the trunk once the root ball has been positioned in the planting hole. Even the tops of the plants as needed.
