There is a cedar tree variety that can be grown in almost every USDA zone. Cedar trees often are used in landscaping for wind buffers, hedges and screening. Selecting the appropriate cedar variety for your zone is essential. Once established, your cedar tree will be easy to care for and resistant to insects and diseases.
Plant cedar trees where they will receive at least six hours of sunlight each day.
Supplement the soil around the cedar with the addition of compost if the soil is heavy clay.
Water the tree so that the soil stays moist but not waterlogged.
Place 3 to 5 inches of mulch around the cedar tree. Apply the mulch in a 3- to 5-foot wide circle around the tree.
