Cryptomeria japonica, or Japanese cedar, with its feathery needles, subtle scent and pleasant pyramidal shape, is a winner in the home landscape. Cryptomeria is a fast-growing evergreen that will keep its impressive, dark green color all year round. Cryptomeria is available in several different sizes, ranging from four to six feet varieties that do well in containers to giants that can reach 50 feet at maturity. A tough, sturdy tree, cryptomeria can tolerate cold winters with temperatures down to -10 degrees Fahrenheit.
Plant cryptomeria in full sunlight or partial shade. Choose an area where the soil drains well. If water tends to puddle five to six hours after a heavy rain, choose a different spot. Although cryptomeria requires plenty of water, the tree won't do well in soggy soil.
Locate cryptomeria where the tree will be protected from harsh winds. Avoid planting the tree too near buildings or other trees, as cryptomeria benefits from plenty of air circulation.
Water cryptomeria regularly and never allow the soil to dry out. As the tree matures, it will gradually become more drought tolerant and will only need water during hot, dry periods.
Prune cryptomeria lightly, only if necessary. Cryptomeria rarely needs pruning, but may need to be trimmed if the graceful, droopy branches hang too low over a walkway.
