THE WORLD OF BAMBOO
Bamboo's natural ranges includes every continent except
Europe and
Antarctica.
We once had 5 million acres of native American bamboo known as Cane
brake (Arundinaria gigantea) growing in our Southeastern quarter. This
bamboo and its ecosystem were soon greatly diminished in area by the
migration of
settlers in the early 19th century. The bamboo grew in good soil and
was
cleared for farmland.
"Stone Age" Asians may have relied heavily on tools they made of
materials other than stone. The lack of stone tools of the quality
found in Europe in much of Asia roughly corresponds to the natural
distribution of bamboo in the region. It appears that Southeast Asia
has been heavily forested for many millions of years. This is still one
of the areas of dense bamboo forests remaining in the world. Man may
have relied more on bamboo than we know. Based on this theory, bamboo
was probably one of the most important raw materials
used by early Asian people. Even today, the use of bamboo has more
significance
to Asian cultures than any other.
Evidence of bamboo use is found in South America. Some excavations of
early dwellings have imprints of bamboo canes and split, woven material
preserved in the mud or adobe used in the construction. Bamboo is an
incredible
grass that has long been in use by people around the globe. In our
modern
world it is finding a new place in the spectrum of plants, fibers and
foods
used to enhance the quality of our lives. We are not simply talking
about
one plant. Bamboo is a large group of giant grasses with over 1,200
species
found from the tropics to temperate regions.
With bamboo's reputation as a fast grower, it is difficult to imagine
that many of the world's bamboo species are endangered. How can this
be? Like many other plant groups some bamboo species live in small
areas of habitat. These areas might be visualized as islands in a
rising sea of humanity. One well known example is the panda and bamboo
habitat in Sichuan, China. Of particular
interest to Americans is the cloud forest bamboo habitats of Mexico,
Central
and South America. Here we can find examples of logging, livestock
grazing
and land clearing that may bring some species of bamboo to the brink of
extinction
in the next 10 years.Recommended reading:American Bamboos. To

There are many factors to consider when thinking about growing bamboo
for ornamental, utility or edible bamboo shoots. To assist you in
making
an educated decision in species selection the most important things to
think about are listed.
YOUR CLIMATE
Do you live in a tropical , subtropical or temperate zone? Note
the hardiness or minimum temperature listed for each bamboo species in
the catalog.
Tropical bamboo may only be grown permanently outdoors in areas that
are frost free. This is probably USDA Zone 10 only: areas like Southern
Florida, Southern California and Hawaii. Tropical bamboo may be grown
indoors or
in greenhouse environments if care is given to maintain steady warm
temperatures throughout the year.
Subtropical bamboo are somewhat tolerant to frost. They grow well in
USDA Zones 9 and 10 with marginal performance of some species in Zone
8. These hardier selections are useful for areas like much of coastal
California, the Gulf States and the tropical areas, as well as interior
use.
The temperate bamboo are quite frost hardy. Some withstand temperatures
to -20 F or USDA Zones 4 and 5. Most will grow around the country in
Zones 6, 7, 8, 9, and many, in 10. Many do well as house plants.
THE PLANTING SITE
While bamboo will grow in most soils it is important to
remember it is not a water plant or a desert plant. It likes water on a
regular basis, particularly in summer. Bamboo likes to grow at the edge
of a pond, stream or swampy area but not in it. Irrigation is necessary
in the west where summers are dry, clear and hot. In the east where
summer rains are a regular occurrence irrigation is not necessary,
except for newly planted bamboo or during drought conditions.
The soil range can be from sandy to clay. Bamboo grows fast and easily
in sandy/loamy soils, however, watering and feeding will need to be
more frequent. Heavier soils also nurture bamboo nicely. In both cases
a heavy mulch of wood chips encourages rhizome growth and maintains
even moisture levels.
Soil pH is recommended at between 5.5 and 6.5 or slightly acid for most
species. Generally, species that tolerate drier conditions may do
better in higher pH soils.

SPREADING VERSUS THE CLUMPING BAMBOOS
Many gardeners are frightened by the running bamboo species
that send out rhizomes traveling for several feet. These are the
culprits of bamboos bad reputation among western gardeners.
Fortunately, there is an alternative type of rhizome growth that
results in the rhizome being very short and, sometimes, almost bulbous.
These bamboos that grow only inches away from the center of the plant
with densely clustered culms are called clumping bamboos.
In simple terms, the spreading or running bamboo are found in the more
temperate climates. The clumping bamboo is of more tropical or montane
origin. The open grove spreading bamboo is what you see in photographs
of people walking through a forest of bamboo. Clumping bamboo forms
tight thickets of canes that are impossible to walk through without
cutting your way first. These are the well behaved bamboo that stay put
when planted. The spreading bamboo needs plenty of space to form a
grove. The best way to enjoy spreading bamboo in the garden is in pots
or in a designated area with the bamboo
contained by rhizome barrier.

USES OF BAMBOO
Landscaping
Known as the plant of a thousand uses, bamboo is for us in
the West, first and foremost a landscape ornamental. For years
gardeners have relished the graceful beauty bamboo brings to the
garden. There are hundreds of species suited to every garden use,
except the production of beautiful flowers!
Dwarf bamboo can be used in mass plantings for a ground cover. Many
gardeners use them as facers between mixed shrubbery or in foreground
plantings. Bonsai and house plant enthusiasts use the little bamboo in
pots around the deck and home. The many sizes, leaf textures, leaf
patterns and colors create a delectable palette to work with.
The shrub bamboo will reach six to eight feet tall. All will grow with
a mounding mass of leaves and very little culm showing. Use for low
hedges, boundaries, fillers, foundation plantings, and for taller house
plants. On the larger estate they are excellent for mass plantings and
erosion control. There are several different leaf colors and sizes
available.
The taller bamboo that are big by homeowner standards but not timber
size are categorized as tall shrub. This group of bamboo reach heights
that are suitable for screening purposes, hedges, small space
specimens, foundation plantings, and large pots. A new group is added
to this size - mountain bamboo. These are very beautiful and
well behaved clumping bamboo suitable for the smaller garden wherever
the climate permits.
The popular icons of bamboo are the timber bamboos. These grow to
gigantic proportions. Many of the tropical species reach huge sizes
that will impress you and your friends. Fortunately, the tropical and
subtropical giants are clumpers. They are practical as a
ÒtreeÓ size plant in many residential lots. The other
group of giants are the temperate running timber bamboo. These are the
grove forming bamboos that need free range and space to attain grand
heights and thick hard culms. The timber bamboos make great background
plants or tall hedges to block out undesirable noise and views. To use
these responsibly in residential lots we recommend installing our
rhizome barrier.

Constructing with Bamboo
Bamboo is a tradition for most people in Asia. Handcrafted
items made from bamboo have been in use since antiquity. It is surely
the plant of a thousand uses, however, we won't go into more detail
here. The best bamboos for crafting various things for use around the
home and garden are listed in the species descriptions and
"Gib's Picks". To use bamboo requires different skills than using
wood. Bamboo is strong, hard and brittle. For example, driving a nail
will split it, you must predrill a hole first. Sawing bamboo requires a
sharp small toothed saw like a hacksaw. We carry several books to
assist the crafts person to learn how to use bamboo in building.
In the past few years numerous techniques in bamboo processing have
brought new products onto the home improvement market. Examples of
these
products include "Plyboo" tongue and groove flooring, sheets and
paneling.
Other paneling products use the beauty of natural split weaves, culms
and
strips to create fine Japanese style interiors. Most of these materials
come from the splitting of the bamboo culm into various sizes, squaring
and pressure laminating into the desired size and shape. This is one of
the most exciting areas in the application of bamboo to solve our
natural
resource problems in the future.

Bamboo Shoots
While Asian cuisine has demanded a variety of bamboo species
to be harvested in season for fresh or canned bamboo shoots, the
American market for shoots has been exclusively imported canned shoots.
The popularity of Chinese restaurants with Americans gave most of us a
taste of this bamboo vegetable. Asian communities are growing enclaves
in many parts of the country. People in these areas want good quality
bamboo shoots - either fresh or frozen. More and more people are
planting bamboo for this vegetable market.
The homeowner with the best bamboo for edible shoots may enjoy the
annual harvest at shooting time. There are many recipes available for
using bamboo shoots. Some species of bamboo shoots are very bitter. The
traditional way of removing the acrid taste is by cooking and washing.
However, the best way to enjoy your shoots is by selecting the best
edible species to start with. Take a look at the recommended bamboo in "Gib's Picks for Edible
Shoots".

Bamboo Paper
Some countries rely on bamboo for most of their paper
production. Commercial paper makers in America may not find bamboo
useful as a raw material without more bamboo acreage and new processing
equipment. The paper making crafts person will find bamboo as a very
desirable fiber for hand made paper .
Bamboo as Fodder
The Japanese have used bamboo as animal feed for hundreds of
years. Only recently have stockmen realized the usefulness of bamboo
feed. There is new research into the food value of bamboo for cattle
and other livestock.

Bamboo Agroforestry Workshop.
The Ecological Uses of Bamboo
Our activities disturb nature. Bamboo is a helpful plant to
reduce our environmental intrusion. There are some areas where humans
and livestock present problems in waste disposal. Bamboo is a heavy
feeder and grows very well if given high levels of nutrients. There is
research into the nitrate uptake and production of bamboo poles from
the waste treatment facilities of towns and farms.
Erosion on America's land continues. Every time someone uses a
bulldozer to make a new driveway or home the soil is disturbed. Rain
runoff carries the exposed soil into our waterways. Prompt planting of
bamboo can alleviate these problems.
Polluted air and views are problems many of us face in our daily lives.
Tall bamboo provides millions of leaves to filter the air, sounds and
views that intrude into our most important space -home. Wise planting
of bamboo around the home, farm and factory will encourage good
relations between neighbors.
