Japanese Maple (Acer Palmatum
Verieties) Bonsai Tree Care Sheet
Hardy/Easy to keep and train/Deciduous/ Suitable For
Beginners

Introduction.
Acer Palmatum are a genus consisting
of hundreds of verities of small deciduous trees and shrubs that
are native to Japan, China and Korea. Acer Palmatum are
very popular with Bonsai enthusiasts due to the beauty of their
leaves, lovely spring, summer and autumn colors and they respond very
well to Bonsai training. There is also a wide variation
to choose from in this genus, differences in growth habit, leaf size,
leaf shape and color, green verities tend to be more
vigorous and robust than red verities although the red
verities are arguably more attractive then their green leaved cousins. All in all Japanese
Maples make excellent Bonsai trees, and are easy to keep and train, they are a good
choice for a beginner outdoor Bonsai tree.
Where To Keep
Them/Watering.
Japanese Maples are a hardy species and are classed as
an outdoor Bonsai tree subject and should be kept outdoors all
year round. They will withstand temperatures as low as - 10c (14f)
but only for brief periods, if prolonged frosts
are expected then it is recommended that you protect
your Bonsai tree by placing it in an unheated
greenhouse or place some winter fleece over your Bonsai tree, this also helps to
prevent die back of finer branches and twigs, placing your Acer
Bonsai tree in a sheltered spot in the garden during
winter will also help. Japanese Maple Bonsai trees can be kept in
full sun all summer in the UK, this will result in your Japnanese Maple Bonsai tree haveing
better autumn colors than if it were kept in a shady spot, however
in extremely hot sun it might become necessary move your
Bonsai tree to a semi shaded position for a while to make sure
that the leaves don't scorch. Acer Palmatum Bonsai trees like plenty of
water especially in summer when in active growth, make sure you check
the Bonsai soil every day and water when necessary, this may
mean watering your Bonsai tree once sometimes twice a day in the hottest
summer months. In winter continue to check the Bonsai soil and water
if it becomes necessary, however waterings in winter will be few and
far between, due to the fact it is cooler and your Acer Bonsai tree
wont be in active growth and will not have any leaves to
support.
Repotting/Wiring/Feeding/And Pruning.
You will need to re-pot
your Acer Bonsai tree every 1-2 years, but only if the
roots become pot bound, the best time to do this is in late
winter or early spring, when the new buds are beginning to
sprout. If your Bonsai tree has a good root system you should
be able to gently lift it out of the Bonsai pot in spring (you may
need to snip the Wire underneath the Bonsai pot if the
Bonsai tree is wired in) and take a look at the roots
to see if they are pot bound, if so you should repot your Bonsai
tree, if the roots seem ok then leave re-potting till the
following year. when it does become necessary to repot
your Japanese Maple Bonsai, you should use a good quality free
draining Bonsai soil. Akadama Bonsai soil is an excellent
choice and can be used on it's own or if you require a more
moisture retentive Bonsai soil you could add some fine potting
bark to it, Moler Bonsai soil is another good choice,
again you could use it on it's own or add some potting bark, you can
also add pumice granules to your soil mix as this aids drainage
but also holds moisture for your Bonsai tree. It is important
not to fertilize your Bonsai tree for around four weeks after
re-potting as doing so can burn the new roots that your Bonsai
tree will be developing, after this
period carry on fertilizing as usual. You should fertilize your Bonsai tree from
spring onwards with a balanced fertilizer such as Chempak, you will usually fertilize your Bonsai tree once
a week or once a fought night but feeding guidelines will differ
from brand to brand so it is best to refer to the instructions on
the particular brand you decide to use. It is best to carry out wiring on
your Japanese Maple Bonsai in spring as the leaves
wont be in the way at this time though you need to be careful
not to dislodge any buds that are forming, it is not recommended to
wire your Japanese Maple Bonsai tree in winter as doing
so can cause the branches to unexpectedly snap as the
branches tend to be more brittle in winter. Don't leave
the wires on your Bonsai tree for more than 6 months, keep checking on
them and make sure they don't start to bite in to
the Acer Bonsai's bark. Prune your Maple Bonsai tree back
to shape throughout the growing season, trim back to one or two pares of
leaves, also remove growth with long internodes (distance between leaves) this
will result in more compact growth, any hard pruning that needs
to be carried out is best done in mid
summer when wounds will heal better and quicker, or in autumn as soon as
possible after the leaves have fallen, it is not
recommended to carry out hard pruning on
Maple Bonsai trees in spring as they tend to
bleed a lot which will weaken your Bonsai
tree. Leaf pruning (defoliation) on Japanese Maple Bonsai trees is a
good idea in mid summer to promote smaller leaves, denser foliage and better autumn
color, defoliation should only be carried out on healthy
Acer Bonsai trees, you should not do this in the same year you
re-pot your Bonsai tree, it is also not recommended
to do this two years in a row, it
is also not recommended for use on weaker red Japanese Maple verities.
The best way to ensure you keep your Bonsai
tree healthy is to do as much research as possible(Internet and
or books) on the particular species you own and also Bonsai in
general as this will give you a broader understanding of the subject
and will give you a far better chance of success with your Bonsai
tree.
