A
multi-trunk or clump-form bonsai has three or extra odd-numbered
trunks rising from the identical root base. This text describes
one technique of growing a multi-trunk bonsai; it additionally illustrates
a method for growing the nebari (floor roots) that may
be used for timber with single trunks in growth for bonsai.

This
bonsai began in early 2003 as three Subject Maple (Acer campestre)
bare-root saplings. All three timber had roots unsuitable for
bonsai as is typical with bare-root inventory.

As
these timber have been to be planted into the bottom for a quantity
of years to thicken and develop the trunks, I took the chance
to develop an appropriate nebari (floor roots) on the similar time.

The
following method makes use of the identical precept as utilizing a tourniquet
to floor layer a brand new rootsystem and combines it with planting
the tree on high of a tile to make sure a flat root system.(See

for Bonsai by Layering)

Three MaplesThree Maples

January
2003: Three discipline maples of various sizes have been chosen
for this undertaking and every is threaded by means of holes drilled
into a bit of wooden. The holes have been made massive sufficient for every
tree (and its branches) to go by means of the wooden with the minimal
of room to spare.

I’ve used a wood board for the timber used on this
article; although the board has produced passable
outcomes, it has begun to rot and break up after four years
within the floor. A greater different is to make use of an previous
ceramic tile although these may be harder to make
holes by means of.

Select
the positions of the holes fastidiously as they may dictate
the ultimate positions of the trunks themselves. Bear in mind
that the trunks will swell over time and the trunks
ought to initially be positioned additional aside than you finally
need them to be.

A
helpful different for single-trunk timber is to make use of
an previous CD; saplings of lower than 1.5cm diameter can
be threaded by means of the opening in the midst of the CD
previous to planting.

trees are then potted up

 

The
timber are then potted up into an appropriate container or into the
floor the place they should be inspired to develop as vigorously as
attainable. Nice care should be taken that no air pockets stay
beneath the tile/piece of wooden and {that a} layer of no less than
3″ of soil covers the floor of the wooden/tile.

 

The
thought of this method is that because the timber develop and their trunks
thicken and broaden in opposition to the edges of the holes, every tree
begins to layer itself; in the identical method {that a} ground-layered
trunk will start to provide new roots above the wire tourniquet.

 

 

Because the
new roots emerge above the wooden, they develop laterally throughout
the floor of the wooden (or tile), unable to journey downwards
till they attain the sting.

 

 

 

 

 

 

The layering process

February
2004: The timber are lifted from their pot and naked rooted. The
layering course of has already began and the brand new roots have
grown throughout the floor of the wooden. Having organized the brand new
floor roots and eliminated any inward rising or crossing roots,
the timber are replanted (this time into the bottom however a pot
would have been sufficient). Once more, the floor roots are coated
by a round 3″ of soil.

The
depth of the soil above the tile should be deep sufficient to remain
moist through the hottest days of the yr in any other case the brand new
floor roots are liable to dieback if allowed to dry out.

I
want to raise trunks being developed this fashion each
yr in order that the brand new floor roots may be organized to
guarantee they’re mendacity flat on the board and rising
outwards in a radial style; this isn’t completely
vital as any ugly roots may be pruned away each
2 to three years if most well-liked.

arranging and photographing the rootsarranging and photographing the roots

November
2004: All three timber have grown properly by means of the yr they usually
are briefly lifted so I can see how properly the floor roots are
growing. Improvement seems wonderful although the smallest tree
has didn’t root in addition to the 2 bigger timber. After arranging
and photographing the roots, the tree is replanted once more.

trunk and root developmenttrunk and root development

February
2007: Simply over two years later the timber are lifted once more;
trunk and root growth has been glorious although there’s
disappointment that the naked portion across the smallest trunk
nonetheless exists.

The
velocity and fee at which new roots seem above the board
relies upon solely on the speed of high development (new shoots
and leaves) of every tree. The extra high development there
is every year, the quicker the trunk swells and the extra
root development that happens.

In
order that these three trunks are of differing sizes,
the smallest trunk has been repeatedly pruned whereas
the biggest trunk has been allowed free and vigorous
development. The results of this pruning regime may be seen
above; the biggest trunk has produced probably the most new roots,
the thinnest trunk that has grown comparatively little
has produced a lot fewer new roots.
