keep/evergreen/Good Bonsai tree for beginners

Introduction.
This Bonsai care guide describes
how to look after an Ilex Crenata Bonsai tree which are native to
Japan, Korea, and Parts of Russia and are part of a genus
consisting of over 400 species of evergreen and deciduous
trees and shrubs. Unlike many of the Ilex (Holly)
species, Ilex Crenatas make a very attractive
Bonsai subject, along with it's dark green leaves in summer it also
produces small white flowers, these are followed by black
berries. When grown indoors Ilex Crenatas are a reliable and easy to keep Bonsai tree and are
suitable for beginners.
Where To Keep Them/Watering.
Although Ilex Crenatas are
a hardy species they are regarded as an indoor Bonsai tree
as they require protection in temperatures below 5c, your Ilex
Crenata Bonsai tree will enjoy the summer months outdoors though
when temperatures don't drop below 5c. When placed
outdoors in summer Ilex Crenata Bonsai trees can
be kept in full sun or partial shade. Indoors you
should place your Bonsai tree on a bright window sill away from a
heat source, a humidity tray is also strongly recommended
for an indoor Bonsai tree, the tray should be a few
inches larger in width and length than the Bonsai
pot, and the Bonsai pot should not come in to direct contact with
the water in the tray, the feet of the Bonsai pot should
be placed on some small stones to raise the pot
above the waters surface, or you could place fine gravel
up to the rim of the tray and place the Bonsai pot on top
of the gravel. Make sure the humidity tray
has the water topped up at all times and as the
water evaporates it will rise up through the leaves of your
Bonsai tree and help to keep the local area more humid,
Ilex Crenatas also enjoy having there foliage misted every now
and then, this will also help
keep humidity up. In winter it is best to place your
Ilex Crenata Bonsai in a cool preferably unheated
room in your home to allow a dormant period for
you Bonsai tree. You should check
the Bonsai soil on a daily basis and water your Bonsai Tree when
necessary, it is advisable to let the surface of the soil dry
slightly before watering but never let it
dry out completely, you will
need to water Your Bonsai tree more often in summer.
Repotting/Wiring/Feeding/And Pruning.
You should aim
to re-pot your Ilex Crenata Bonsai tree every other
year, the best time to do this is in late spring as
buds begin to open. If your Bonsai tree has a good root system
you should be able to gently lift it out of the pot in spring (you
may need to snip the Wire underneath the 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 Ilex Crenata Bonsai tree, you should use a good quality
free draining Bonsai soil. Akadama Bonsai soil is
an excellent choice, this will need to be made more moisture
retentive by adding some fine potting bark to the
mix, Moler Bonsai soil is another good choice, again
add some potting bark to the mix for moisture retention, 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 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, discontinue feeding during winter and begin
feeding again in spring. Wiring should ideally be done in spring, leave
the wires on for up to 2
years to let the branches set,
however check the wires regularly to make
sure they aren't cutting in
to your Bonsai tree's bark. Trim the the new shoots
back when necessary during the growing season to keep your
tree in good shape.
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.
