A Bonsai Close Up on Phoenix Grafting
by Pauline F. Muth
The incredible age depicted by venerable old trees surviving
the decades showing the scars of age in jin and shari has fascinated
all of us. Driftwood styled bonsai depicts the essence of antiquity.
But alas, finding the material needed to create one for our collections
is difficult at best. Buying such a masterpiece can tax the wallet
or be totally beyond our means. One solution is the creation
of a phoenix graft. Just as the mythical phoenix bird rises from
the ashes of death, a masterpiece bonsai can be created by combining
a younger living tree with a beautiful piece of driftwood.
The driftwood may come from a once loved bonsai, now in permanent
dormancy or from a beautiful piece of wood found in the mountains,
along a stream or the ocean. Look for pieces with interesting
natural lines. The piece may be modified with careful sculptural
techniques, but the lines must be natural and artistically appealing.
The living tree will be attached to the back and /or sides so
select wood that has a pleasing front. The living material should
have a flexible trunk and branches to facilitate bending it to
the shape of the driftwood. Ideally, the driftwood and living
material are of the same species. Acceptable results can be achieved,
however, if both appear similar.
Many species have been
used for this treatment, among those often used are:
|
apricot |
common juniper |
oak |
|
azalea |
cotoneaster |
pines |
|
birch |
dwarf honeysuckle |
pomegranate |
|
cedars |
hawthorn |
quince |
|
cherry |
hornbeam |
rhododen-drons |
|
cypress |
firethorne |
willows (great for beginners) |
|
Chinese juniper |
jasmine |
wisteria |
This technique should be done in early spring just as dormancy
is breaking. The plant will have the best chanceof survival when
given the longest period of time to grow and recover from "surgery"
before winter dormancy.
The Technique
|
1. Prepare the piece of driftwood
and make any design modification desired. |
|
* Using a wire
brush, and perhaps a soap solution, carefully scrub the driftwood
clean. Remember to
work with the grain as you scrub. Be careful to eliminate any
pockets that will hold water later and
lead to rot. Remove any remains of bark. |
|
* Using a hand or motorized
carving tool, make design modifications as desired. |
|
* You may wish to carve
a groove into the back of the trunk marking the line to which
the living trunk
will be applied later. This procedure often allows the resulting
graft to look more natural han
those applied to a flat surface. |
|
* Treat the clean wood
with a good wood preservative like Thompson's Water Sealant.
You may wish
to bleach the wood using lime sulfur before using the sealant. |
|
* Form an anchor
for the driftwood by attaching a wire support as a base. Wrap
chicken wire around
this if the base is very large. (I have also used fiberglass
cloth and fiberglass for this part with
smaller trees that are not top heavy.) Cover this wire base with
plastic body filler or hydraulic
cement to act as a counter weight to the driftwood and the living
tree. Consider the shape
and size of the eventual pot as you do this. Brush the filler
up onto the trunk being careful not
to go above the proposed soil line. This will protect the base
of the driftwood from soil line rot. |
|
* When the filler is
dry, drill at least 1/4inch diameter holes through it to allow
for water drainage and the
future growth of roots through the base. |
|
2. Prepare the plant material. |
|
* Remove the plant
material from its pot and clean some of the soil from the roots.
Wrap the root
ball to keep the roots moist. |
|
* Using a very
sharp knife, cut away a small section of the trunk's bark and
cambium layer on the
side to be attached to the drift wood. This must run in
a line from the trunk base to the upper most
point where the trunk will be attached. This will
allow the future callus to form attached to the
driftwood. |
|
* Trim any unneeded
branches from the tree. |
|
3. Attach the tree to the driftwood. |
|
* Place the tree
along the driftwood and attach it using one or more of these
techniques: (Remember it
is vital to attach the trunk securely without air spaces. The
exposed part of the trunk is placed against
the driftwood.) |
|
o Use black-root-over rock
tape to attach the trunk by winding it around the tree and driftwood. (I prefer
this because the tape holds evenly, stretches with time and does
not degrade
for several years.) |
|
o Strap
the tree to the driftwood using raffia that has been soaked in
water. |
|
o Wind
commercial packaging material around the trunk that was first
protected by bits of soft sponge. |
|
o Use
plastic cable fasteners to attach the tree. (I find this method
is only good for positioning.
Scarring results
from using these straps as the main securing agent.) |
|
o Use
tiny brass screws to attach the tree trunk first. The tree eventually
grows over these screws.
Then secure with your choice of wrapping. |
|
* If the method
you used left parts of the cut trunk exposed to the air, apply
grafting wax to each side
of the trunk line to prevent drying out and insect and fungal
infestations. |
|
4. Pot the phoenix graft. |
|
* Soak the root
ball in a Superthrive or other transplanting solution. |
|
* Prepare the
pot with wires, drainage screening and a coarse drainage bonsai
soil mix. At this stage it
should be generously potted. |
|
* Plant the tree
making sure the spread the roots over the base of the driftwood
support. Use a compost
heavy bonsai soil mix with good drainage properties. Wire the
base and roots in well. Dust
the roots with rooting hormone to promote new root growth. |
|
5. Grow the tree on. |
|
* The resulting
tree should be grown in sunlight for several seasons using a
regular fertilizer and watering
schedule. |
|
* Some trimming
may be done, but vigorous growth is needed to promote the growth
of the trunk into
the driftwood |
|
* Watch for scar
damage. The black tape method usually prevents this from occurring. |
|
* After at least
three years the taping can be carefully removed. |
|
6. Style the tree. |
|
* The graft will
become more secure with age, but at first be careful of placing
stress on it when wiring
it. |
|
* Repot as needed
taking care not to destroy roots that have passed through the
holes in the driftwood's
artificial base. |
