Cryptomeria fortunei is round and tall, and its trunk is thick and majestic, which is most suitable for single planting, opposite planting, cluster planting or group planting.
Cryptomeria fortunei is an evergreen tree with a height of 40 meters, a straight trunk and a conical crown tower.
The bark is reddish brown, and the fibers are split into long strips and peeled off.
The big branches extend obliquely or horizontally, and the branchlets often droop.
Leaves subulate, slightly curved inward.
The male cones are yellow, the female cones are light green, and the flowering period is April.
The cone is dark brown when it is ripe, and the fruit ripens in 10 ~ 1 1 month.
Cryptomeria fortunei is a moderately positive tree species, which has a little tolerance to shading and cold tolerance.
I like high humidity air, but I'm afraid of summer heat or drought.
It is suitable for growing on deep and fertile sandy loam with good drainage to avoid water accumulation.
Cryptomeria fortunei is a single-axis branch, but the top advantage obviously decreases when it is aging, so the top of the old tree often drops to a circle.
It germinated in late March, peaked in April-June, stopped high growth in July-August, then turned to coarse growth peak, and stopped growing in September 9- 10/October.
It grows fast and dry in its infancy, and its annual height can reach more than 50 cm. After the age of 30, the height growth is extremely limited, and it is mainly thick and long, which can last for hundreds of years.
Cryptomeria fortunei adopts the plastic way of central trunk and low branches.
Because of the dense leaf curtain, plastic surgery is easier, but attention should be paid to properly protecting the trunk and lower branches of the central leadership.
Cryptomeria fortunei is pruned less, mainly to prevent double tips at the top of the tree. When the two tips are neck and neck with the main tip, one should be cut off in time, otherwise it will affect the tree shape.
Cryptomeria fortunei leaf curtain is dense, and the surface of conical or wide conical crown should be flat.
Branches with suitable azimuth and opening angle and too strong growth potential should be picked as soon as possible.
If there are branches protruding, it will affect the viewing effect. Keep the protruding branches down by changing their heads on the fragile branches below.
After the twigs of Cryptomeria fortunei wither, the leaves are brown but do not fall off, so they should be cleaned in time.
The seedling shaping and maintenance and pruning time of Cryptomeria fortunei is in spring, and the maintenance and pruning can be done once a year.
