The willow-leaf fig is known in bonsai as Ficus Salicifolia and
Ficus Neriifolia none of witch is scientific names. The true Ficus
salicifolia is a native of South Africa and has a willow shaped leaf
similar to our willow-leaf fig but the leaf is larger and the tree
does not grow as compact.
The tree grows to about 15 feet in my area and will produce some
aerial roots if the canopy is allowed to spread, the trunk will
develop a buttress with nice surface roots, the bark is grey
although it will become red if it is exposed to the sun. The leaves
are alternate, lance late, although the new leaves are curved and
tawny in color as they mature they straighten and develop a healthy
green color. The green figs are small about .25″ turning a brick red
with brown spots when ripe.
Our growing conditions in Vero Beach are subtropical, we get
frost and occasionally we will have a hard freeze this usually lasts
for one night. All of my bonsai are growing outdoors therefore it is
necessary to cover them when we expect a freeze. Since my bonsai are
growing on pedestals I have made a bag using agricultural
winterization cloth that will fit over each plant, it is easy to put
on and easy to remove.
Since Ficus Salicifolia is succulent it can go for long periods
without water, if the plant is not watered in a reasonable time it
will drop its leaves. It can live in this condition for a short time
if it is healthy and in a humid environment. Ideally the plant
should be watered thoroughly and the soil be allowed to approach
dryness before the next watering. Any well draining bonsai soil is a
good growing medium for this Ficus.
We do get a lot of rain in Summer which is not a problem if you
use a well draining soil, since our Winters are dry, this can be
good since the plants are not growing as much.
Most Ficus are not heavy feeders but they do respond to regular
applications of a balanced fertilizer, if you use a liquid plant
food it is important to apply it on a regular schedule during the
entire growing season. A slow release formula that may last three
months or more might be better for someone that does not have the
time to maintain this strict schedule. Always follow the directions
on the label.
They can be grown indoors if given the right environment. Light
is usually the limiting factor but humidity, air circulation and
temperature are just as important if you want to keep the plant
All plants are started from cuttings you can use tip or cuttings
as large as you have available. I start mine in perlite but any well
draining soil will do, early spring has proved to be the best time
to take cuttings. Large cuttings are started in 6″ pots and are
allowed to grow in them until the following spring before
transplanting to your normal soil. It takes about twelve weeks for
them to root in my environment. If you are rooting them under mist
it is important to have good air circulation to reduce the
possibility of fungus.
Air layering is another method to propagate this plant, large
caliper trunks can be used thus reducing the time required to
produce an old looking bonsai.
Another method is used to create a group planting from a root
cutting. When the root ball is cut from a large bonsai the roots
that were removed will sprout if they are planted so that the top of
the root ball is even with the soil surface. After the first year of
growth remove any trunks that will not be needed for your forest,
allow the trunks that will be your main trees to grow unchecked in
order to develop a large caliper, the remaining trunks should be
shortened accordingly to create a variety of sizes for your forest.
Insects and Diseases
Insects and diseases have not been a problem if the plant is
healthy and good air circulation and light is provided. Over
crowding is the usual cause of fungus, fungicides can be used as a
preventive or if the plant is heavily infested leaf removal may be
the best solution. If fungicides are used always follow the
directions on the label.
This plant can be used for any style but since it is an upright
tree it is not normally used for cascades. It develops a trunk with
a flared base and heavy surface roots. When cut back hard new buds
appear over much of the trunk so that you have many choices for
selecting branches. Aerial roots are a plus if you wish to create a
banyan style, a humid environment and a large canopy of foliage will
encourage their formation. The direction of the roots can be
controlled by placing a split soda straw between the root and the
soil as soon as the root appears.
It is important to split the straw its entire length so it can be
removed after the root grows through the center of the straw into
When styling this tree you can be as drastic with your root
pruning and top pruning as you wish to create the style you want,
this plant is very forgiving, ideal material for the beginning
bonsai artist. Wiring is only required for the initial styling after
that the clip and grow method is usually used to develop the bonsai.
Since the roots can be drastically reduced it is possible to plant
the tree in a very shallow pot, which is very appropriate for a
banyan style. Being able to drastically reduce the height of the
plant it is possible to create a low ratio of tree height to trunk
caliper. This bonsai is usually seen as a single trunk upright
style, but it is ideal for group plantings, literati, driftwood etc.
Start the styling by finding the front of the tree, first look at
the trunk if it is straight any side could be used as the front, if
it is slanted it could lean to the right or to left but never
backwards. If the trunk is curved it is usually viewed from the side
that shows the most interesting movement.
The length of the trunk is determined by several factors. A short
tree will make the trunk look bigger and older than a tall tree with
the same size caliper; a tall skinny tree looks juvenile. If the
trunk is straight shorten it to the point where the taper stops, if
the trunk is curved you may want to continue up the trunk until it
Next remove the soil so that the surface roots are exposed,
examine them from all sides pick the side with the most impressive
roots and flare of the base, ideally the surface roots will be in
proportion to the size of the trunk and will radiate out from the
trunk. Choose the side with the most pleasing appearance.
The arrangement of the branches is sometimes determined by what
is available. If your plant has a lot of branches to pick from,
start by choosing your lowest branch, which should be on the right
or left side. The second branch should be on the opposite side and
slightly higher except on a banyan style, both branches should come
slightly forward. Ideally a back branch will start between these two
main branches. The other branches will revolve around the trunk and
will become closer together as they near the apex. No branch should
be allowed to grow directly above the one below it and no branch
should be heavier than any one below it.
Wire all branches after you have selected the ones you want and
adjust them to suit the style you have chosen. Be sure to remove the
wires before they damage the bark, this may be as soon as a few
weeks, depending on your growing conditions.
Pot your plant the same as any other bonsai keeping in mind that
it is always possible to choose the correct size pot because you may
reduce the root ball to fit any pot. Choosing the correct pot for
your bonsai is very important. The pot should compliment the tree
and be in proportion to the size of the tree. The length of the pot
should be approximately two thirds to three fourths the height or
width of the tree whichever is greater. The depth of the pot should
be large enough to accommodate the roots the height should
approximate the caliper of the trunk. Peculiarities of the specific
tree may require you to deviate from these guidelines. The pot
should always balance the tree; a massive looking tree will need a
heavy looking pot while a younger looking tree will need a more
delicate pot. Literate style is usually potted in a shallow round
pot, banyan style looks good in shallow oval pots, blooming plants
are enjoyed for their flowers therefore a glazed pot could be used
to compliment the color of the flowers and cascades need a tall pot.
Make sure the plant is securely wired in the pot and always plant
in dry well draining bonsai soil. Study the bonsai and make any
adjustments you may need to make before you water it. It is not
necessary to soak the soil immediately, in my humid environment I
sometimes wait until the next day before drenching the soil.
It is important to give the bonsai proper aftercare, it should be
placed in an area where it will get filtered sun and good air
circulation the soil should be kept moist but not wet
Refinement should start as soon as the plant is healthy and
growing vigorously. First remove all the leaves and the unwanted
branches, shorten the branches to fit in your silhouette. After new
buds appear it will be necessary to remove all the unwanted buds
that have sprouted on the trunk and branches, keep any new buds that
are needed to complete the design. Rewire all primary and secondary
branches that need to be repositioned. Study the design and remove
any growth that is too long or is growing outside the silhouette,
remove all terminal buds except those you wish to lengthen.
The next flush of growth will develop with smaller leaves and if
pinching is continued on a regular schedule throughout the growing
season the leaves will remain small. Pinching is the removal of the
young tender growth at the end of each branch, it may be the
terminal bud or it may be longer and include several leaves. The
leaves on this plant are alternate and revolve around the stem.
There is a bud at the base of each leaf, if we pinch back to a leaf
that is growing on the side of a branch the new bud that sprouts
will grow on that side. Therefore it is possible to direct the
terminal growth of each branch in the direction we wish by pinching
back to the leaf that is growing in the direction.
When pinching always keep in mind the shape you are trying to
create and pinch accordingly. When looking at a branch from the top
it should have a triangular appearance. The side view will have a
flat bottom with no growth extending downwards, the top should be
contoured so that the highest part should be closest to the trunk,
and the end of the branch will taper to a point.
When working with mame bonsai we sometimes need to shorten a
branch to a leaf that is not growing in the direction we desire. We
can correct this by wiring the tip of the branch and twisting it in
the direction you want the terminal bud to grow. The wire needs to
be removed shortly after the new buds starts to grow.
