Bonsai Security
A friend
returned from Tokyo recently and recounted his amazement at the
freedom from crime that the population (including bonsai artists)
enjoy in Japan. He was able to walk along narrow alleys behind
and between houses and observe many hundreds of bonsai with no
fences or security measures to spoil the view. Unfortunately we
cannot employ the same trusting methods here in the UK.
Thefts from
gardens have become an increasing problem over recent years.
Determined thieves have been known to lift all the conifers
planted on front gardens down an entire street! The attraction of
Bonsai, which are ready potted for easy transport and commonly
thought to be all of great value, can place collections in
jeopardy. Even well known, ancient, specimen trees that are
readily identified and unlikely to be saleable have been stolen.
Despite the
above, don't allow paranoia to spoil your enjoyment but take a
few simple precautions, to minimise the chances of theft and so
that if you are unlucky, there is a chance that all will not be
lost.
Depending
upon the amount that you worry, your location and finances, one
or more of the following could be employed:-
- Don't
"advertise" the fact that there are bonsai
about. Simple things like "I Love Bonsai"
stickers on car windows, Bonsai club posters with
addresses on them, or bonsai accoutrements plainly
visible from a main road, can act like thief magnets.
- If you
are ever "lucky" enough to attract the interest
of the press make absolutely certain (get it in writing
if possible) that they are not going to print your
address along with the photo of you with your prize
winning tree/garden etc. This has happened to two
colleagues in recent months without their permission.
- Site
your collection carefully. A part of the garden that is
not overlooked from a main road is sensible. Keeping the
collection in plain view from the house, helps deter
thieves and increases your daily enjoyment.
- Give
some thought to the boundaries of your property. Who can
see in and how easy would it be for a potential thief to
enter and exit? Replace any broken fences, giving due
thought to whether they will be climbable or easily
broken. Make certain that hedges are sturdy enough to
prevent a determined assault (flimsy hedges like privet
could have posts and wires placed through the centre to
stop it being parted and walked through).
- Many of the thorny shrubs used for security can also be used as sources of
bonsai material.
1 Hawthorn a flowering deciduous thorny shrub
2 Variegated Holly
3 Pyracantha - Firethorn is a tough thorny shrub with flowers and berries
4 Rambling or Climbing Rose
5 Berberis - Dense shrub with prickly leaves and thorns
- Dense thorny hedges or shrub barriers are very effective once
established. Berberis, Hawthorn, Sloe, Pyracantha or
Gooseberry could be used and also double as a potential
source for bonsai air layers and cuttings in future.
Rambling roses or any other thorny plant massed against a
wall or fence make it much less inviting to the potential
burglar. Low walls or fences could have a trellis fixed
over them to make them suitable for growing a higher
barrier of climbing/thorny plants. This gives more
privacy from neighbouring gardens and helps prevent
anyone simply vaulting the wall.
- Make certain that any paths around the house to the area where
your trees are sited are closed off by a high, secure,
lockable gate. It is a nuisance, but try to keep it
locked at all times when it is not in use.
-
- Be
aware of who is about when you transport your trees onto
or off your premises. If there are strangers around, be
cautious about carrying your specimen trees openly. It
would be more sensible to place them in a large, strong
cardboard box or similar.This procedure will also serve
to protect fine twigs and branches from damage in
transit. Alternatively just move your trees when you are
less likely to be watched.
- Maintain
a photographic record of each of your trees in all
seasons. This should be done anyway as it increases the
pleasure and value of a collection if good records are
kept. Keep the photographs updated if you alter the
styling of a tree, or every five years or so as it
matures. In the event of a theft, the photo's would be
useful to show the police what is missing, assist in any
insurance claim, and prove ownership of the trees if they
are recovered.
- Mark
the inside or underneath of all containers with your zip
or post code and house number in indelible pen or
similar. Alternatively use a grinder in a power tool to
carefully engrave it. If you ever commission a pot, ask
for your post code and house number to be moulded or
stamped on the base. See also BonTag below.
- Install
a system whereby the trees are inconspicuously fixed to
the display bench. This can be achieved by arranging a
strong wire loop through the drainage holes fixed, for
example, by small padlocks, to a chain that passes
beneath the slatted top. If correctly arranged this
should be taught enough to prevent the wire being cut and
should be unobtrusive. An added advantage is that it
helps prevent strong winds from toppling containers and
trees. If you don’t want to have to unlock your tree
to rotate it (for its health - equal exposure to
sunlight), include a swivel on the wire. To keep the
trees in the containers they must also be secured by
wires over the roots and through the drainage holes as
newly potted specimens frequently are. This is a fussy
arrangement but infinitely preferable to an unsightly
steel cage!
- Install a security
light that is activated by a motion sensor or PIR. If
using the former, it is difficult to ensure that its
sensitivity only picks up human movements and that its
range covers the whole area that your trees are sited in.
A light that is triggered by cats and trees moving in the
wind is likely to cause annoyance to you and your
neighbours. A passive infra-red detector is preferable as
it should not suffer from these problems. Incidentally,
exterior lights are also of great use to the owner for
working later into the evening than daylight allows.
- Install
an alarm system. There are now a choice of modular alarm
systems suitable for garden use. They are stocked by
large DIY stores and some Garden Centres. As an example -
the Beta-Thief2000 kit has a waterproof motion sensor, 2m
cable, 114 decibel weatherproof siren, blue strobe light
and a combination locked on/off switch.
- A more
complex system employs infra red beams which, when broken
by an intruder, sound the alarm. This could activate a
buzzer in your house, switch on a security camera and
vcr, sound an alarm or floodlight your benches. A direct
link to the police station may sound appealing but the
time taken to attend the many call-outs means that often
the thief is away before the scene is visited by a police
patrol.
- Have a
CCTV (Closed Circuit TeleVision) system installed. The
technology has fallen dramatically in price and many
options are available. Monochrome (black and white)
cameras are much more light sensitive than the more
expensive colour cameras. They can even operate
successfully in moonlight.
- Cheap
systems are generally intended for monitoring visitors to
your front door but there’s nothing to stop you
pointing the camera toward your trees instead. This would
allow you to occasionally monitor the security of trees
from your armchair live on the TV in the evening.
Alternatively the video feed could be run to the AV/Aux
or Camera input at the back of an old video recorder and
the tapes recycled after trees have been visually
checked.
- More
professional systems can employ passive infra-red sensors
to trigger a bright light and a dedicated security VCR.
These record 24 hours on one tape and every frame of
video is time and date stamped. They cost a little more
than a domestic VCR (£300-£400) but may suit the
requirements of someone with a large or valuable
collection. Additional dummy cameras can add to the
deterrent effect. They are indistinguishable from the
real one, make the system more obvious and give
apparently greater coverage.
- Anyone
attempting a theft is likely to give up when their
efforts result in a floodlight illuminating them,
revealing security cameras and perhaps a loud siren
announcing their unwanted presence to the household and
neighbours.
- Install
a transponder tag such as a BonTag inside each of your
valued trees. These marvels of miniaturisation contain a
microprocessor circuit pre-programmed with a ten digit
alpha-numeric code. It is contained in an inert 12mm
long, 2mm wide, bioglass cylinder and may be interrogated
by a remote reader to determine the identity of the
tree's owner. They have an infinite lifespan and their
unique encoding cannot be erased. Drilling holes in
trees, for security measures, may appear a bit drastic
but is more easily accomplished than it sounds. The hole
should slope upwards slightly and can be filled afterward
with an unobtrusive waterproof filler or the cambium
allowed to grow over sealing the hole. Alternatively the
transponder could be attached to the inside of the pot
with araldite. Some pot manufacturers are now considering
leaving spaces in the body of the pot which could receive
a transponder and be covered over with car body filler.
For this system to be of any use as a deterrent, it has
to be advertised plainly, close to the trees. If the
trees are recovered after a theft, the BonTag system
proves ownership without question.
- Keeping
a dog with a loud bark may be a good deterrent to
intruders but you must also consider the safety of your
collection. Dogs can be a nuisance, at times, in the
garden. A friend's dog knocked trees off display benches
while chasing a cat. Bitches kill patches of lawn when
they urinate on it. My German Shepherd is currently in
training to stick to the paths and not trample all around
the recently finished Japanese Garden. This is not an
easy task! Even more difficult is persuading her that
plants in pots are not toys. When left to her own devices
she finds no greater joy than to demolish a recently
potted cutting or tree, shaking all of the soil off and
leaving it out in the sun to die.
- Adequate
insurance should be considered and all the options
investigated. Not many household insurers will consider
plants over a certain total value (approx. £500) to be
within their policies. A specialist policy is almost
always required when the plants are easily moved -
planters, hanging baskets, bonsai etc. Most insurers are
keen to hold onto your business though, so if you have
taken what you consider to be adequate precautions,
explain this to them and ask that they consider extending
the policy to cover your plants. My broker has told me
that is not unknown for them to do this up to a value of
£1,000. For collections of greater value it would be
sensible to seek out a specialist garden insurance
company. Incidentally, most insurers don’t cover
damage caused by pets. Damn!
Given
adequate thought and preventative measures, you can minimise the
risks. If you maintain a sensible level of awareness, you should
be able to continue to enjoy your trees without the hassles of
any unwanted attention.
