The weeping blue atlas cedar has a dramatic appearance that will add interest to the landscape. It has silvery blue needles on pliable branches that need to be staked and trained. It grows 5 to 10 feet tall but can spread to 20 feet. The tree is hardy in USDA planting zones 7 and 8 and will grow well in parts of zone 9. The cedar is an evergreen conifer that is slow growing. There is a little more maintenance with this tree than most, because it must be trained.
Provide a wooden stake for the desired height of the tree while it is young. Tie the central leader to the stake loosely. Train the tree to the shape you like by pruning off branches that go in the wrong direction during the winter while it is not actively growing.
Water the cedar to keep the soil moist during the first growing season. The tree is very drought resistant once it is established and will need to be watered only during times of very hot, dry weather.
Apply an evergreen fertilizer each spring as the tree breaks dormancy. Follow the manufacturer's directions on how much to use per size of the tree.
Apply a two-inch layer of compost on the soil over the root system in the summer. The compost will leach into the soil as it is watered and help to keep the soil well drained as well as add some nutrition.
Shelter the tree from strong winds, especially in the winter, because the cold air may damage some of the needles on the top of the tree. This can be done with other plantings or by erecting a wind-break wall.
Keep the soil under the spread of the tree weed free. Apply a two-inch layer of dried leaf mulch to the area or hand pick weeds as they appear.
