Sun
Bamboo species
likes different grades of sunlight and temperature. But
all bamboo like protection on the hottest part of day. Tropical
bamboos often like sunny and hot days, while temperate bamboos
prefer colder climate.
Planting
To stablish
a sucessfull planting we should first choose right
species, the right season and right location
(and sometimes right objectives). It's always good remember
that temperate bamboos like more cold, while tropical
bamboos adapt better in warmer climates, but there is exceptions
to both cases. Having an open site near a water course
help bamboo to spread fast. Bamboos retain water in soil,
planted on a steep or river bank make soil strong against
erososions and earthquake damages . Best time
to plant is after winter, with new shoots sprouting,
because they will have time untill next winterto store energy
and nourishment. A bamboo forest or turf takes from
10 to 15 years to reach maturity, having big and
strong culms.
To achieve
an aesthectic effect on a garden design
we should choose the species with desired height and delightfull
color. A bamboo garden produce shadow, give some wind
and rain protection, and makes pleasant sounds
as long there is a breeze. "Bamboos" book,
previously named, is directed for bamboo use in gardening.
In order
to collect good construction bamboo poles we should choose
strong species from medium to giant size. Species in
genus Phyllostachys are largely used in Asia, Europe
and America. Phyllostachys aurea, known as "golden
bamboo", strong and pest resisting, occurs in Brasil in
great number. Some specialists affirm that P. aurea could not
grow in Brasil as big as in other colder countries, but nothing
is certain yet. Phyllostachys pubescens , known as Moso,
is the one used to make bamboo flooring (Plyboo), and also general
construction. This bamboo is very rigid, having medium to large
size. Phyllostachys bambusoides is another species very
used in the world. In Brasil we often see Dendrocalamus asper
plantations, a tropical giant bamboo. This genus, Dendrocalamus,
possess greatest bamboos species. The asper is resisting
and absorbs compression very well, being very usefull to general
construction, altough it demands care with insects. Guadua
genus seems to be best construction bamboo. It generally has
thick walls and great resisting, and is the material of centenary
houses in Colombia. There is native Guadua species in Brasil
as tagoara, but angustifolia adaptas well in our
climate, and shouldn't be forgotten.
In order
to obtain bamboo edible shoots we could use Bambusa
vulgaris, but some say that is a bit bitter. Bambusa
arundinacea has edible shoots, and also produces edible
seeds. Dendrocalamus asper is a favourite in Thailand,
being very sweet.
Technics
There is
some technics in bamboo planting. They depends on available
resources, transport and technology. Moast used form is vegetative
propagation. Could be by culm, rhizome or branch
separation. This propagation methods depends on existence of
live (dormant) buds. They are found on young bamboos, of less
than 2 years.
rhizome
separation:
one should choose a year old (maximum) rhizome.
Pachymorph has to be cut on the neck, where it's connected
to the older rhizome, and over the first node of its young culm.
Then plant vertically, with the cutten culm outside earth, or
horizontally, both cases a few centimeters under the surface
(30-50 cm / 12-20 in).
Leptomorph without culm has to be cut with at least three
nodes with some dormant buds. Then plant horizontally from 30
to 50 cm deep.
In case of leptomorph rhizome with culm it has to be
cut with at least three nodes with some dormant buds and over
the fist node of the culm. Then plant rhizome horizontally from
30 to 50 cm deep, with the cutten culm upwards.
