To
the left is one of the culms enclosed to form the square shape. In my
experience it is best to have an expandable enclosure that can be
adjusted. Depending on what you wish to attend in the shape,
adjustments can result in an inward fold in the culm or a tapered
square form. If adjustment is held tight in certain areas perfect
or uniform square sections of culms can be obtained.

from a different angle showing the corner with tip of culm sheath
revealed.
Note the tiny hair covering the culm ( cane ) sheaths. Even the new
culms underneath these coverings have tiny hairs. The full name for
'Moso' is Phyllostachys heterocycla pubescens. The word pubescence
means covered with fine short hairs. These tiny soft hairs weather away
from the canes usually by the second year.

Culms
held the squared shape 12 feet up on some of the specimens. The
height placement of the enclosure will determine many factors.

Enclosures
have been removed revealing the squared culms. Timing here is important
for sheaths to fall away. If they are kept too long the culms will be
damaged. If they are removed too soon the culm growth is retarded and
their normal height will not be attended.

A
closer view showing the same two culms. Since they have never seen the
light of day they are pale yellow in coloration. This will change soon
they will turn their normal beautiful green.

Another culm removed from the enclosure a few days later due to it's delayed shooting time. |

View
showing
a three inch diameter culm in the background that aborted. This
is a normal variant with 'Moso'. Some years over 40% of shoots abort
with the rest completing their growth period over a 60 day span.
Emerging from the ground in our climate zone during the middle of
March. By the end of May all have grown to their full height and
limbed out with leaves. A three inch diameter culm of 'Moso' will be
over 50 feet in height and will have done this in two months
time.

Close
up view of two squared culms
from a angle shot. Shadows of the culm sheaths are apparent on these
after they fell away.
These areas will fade as the sun light turns them green. Culm sheaths
should be allowed to fall away naturally. Removing them early will
result in shorten height of the culms.

Another close up shows the indented area where the sulcus groove will form further up the culm. A 'Moso' pole will need to harden off for three complete years on average before cutting. If it is cut too early that is a likelihood of the wall splitting. Season cracks are fine, but you would not want a complete crack to occur after all this work. |

May 1st, 2004 My latest
photo shows how this culm has changed in color from yellowish to green
after a couple weeks of sun exposure. On the above photos you can see
the yellowish color of the culms after the enclosure was removed.
Moso culms have a beautiful light olive green color for the first
couple of years. Most will begin having golden colored areas showing up
after two year of age. Those culms in full sun will turn completely
golden with
age.
