AN orchard requires a constant and
rigorous schedule for watering,
nutrition, weed control, spraying
and pruning, not just to maintain it well
but improve production outcomes in the
With summer fast approaching, proper
water management to prevent trees from
becoming stressed is critical to the next
production cycle. But remember: too much
water can be bad.
Soil moisture monitoring using electronic
probes is an effective method of keeping
on top of water problems.
Given that most orchards today are watered
by micro or macro drip irrigation systems,
filters and emitters need to be checked and
serviced regularly. This becomes more
important if nutrients or chemicals are also
administered through the dripper.
Depending on the quantity of summer
Enviromist Spraydome is designed to create one to two-metre spray bands on either side of
tree trunks to reduce weed competition for water and nutrients and for mid-row weed
control as shown here.
▲ A clean orchard floor can be best achieved with a mulcher such as the one pictured here. It
smashes, pulps and clears-up post-harvest debris that could harbour a host of pests.
In a sprayer such as this Silvan tall tree unit,
soft and well-targeted chemicals can be
applied to minimise impact on beneficial
insects within the orchard.
In recent years, deep ripping and
cultivation of the mid-rows has been
replaced with regular mowing, leaving
the floor area of the orchard in a
lawn-like status for weed control.

Generally speaking, a one to two-metre
spray band should be maintained on either
side of the tree trunks to reduce weed
competition for water, nutrients and light.
There are a number of specialised spray
applicators – fully shielded to avoid
chemical drift and protect the trees – that
can be mounted on tractors, all-terrain
vehicles and the like.

THE wraps are off the 2012 CF500 all-terrain
vehicle (pictured), which CFMoto Australia
says is one of its fastest-selling units this year.
Powered by a 493cc liquid-cooled, single-
cylinder, four-stroke engine, it comes in 2WD
and 4WD models with high and low ranges
and an ability to lock the differential when
extra traction is required.
A solid independent rear suspension
package is designed to minimise body roll and
ensure a smooth and stable ride while a 19-
litre fuel tank extends time between fill-ups.
Front and rear racks come in handy for
carrying cargo with winch, integrated
indicators and a tougher exterior
complemented by a CVTech transmission.
The CF500 is priced at $5990.
CFMoto keeps up the pace
Depending on seasonal conditions and
the regularity and quantity of rain, this
under-tree weed control practice may have
to be carried out more than once.
Mid-row management on many orchards
has changed dramatically in recent years.
Deep ripping and cultivation of the mid-
rows has been replaced with regular
mowing, leaving the floor area lawn-like as
a means of weed control.
There is a range of mowers and slashers
available, many of which have a deliver y
function for placing the cut material at the
base and around the grass-free tree trunks
as moisture-conserving mulch.
Orchard maintenance in summer
includes pruning which is usually more
about tree shaping and overcrowding
issues more than anything else.
Pruning in summer does not invigorate
the trees to stimulate new growth like
dormant pruning does in winter and
spring. It’s more of a ‘housekeeping’ job,
to keep trees neat and tidy.
But it introduces another job – cleaning
up. The best treatment here is a mulching
machine to smash and pulp the cut
material into a usable form.
Pest management is another vital job.
Left untreated, the orchard could become
a harbour for disease.
For the same reasons, fallen fruit must
be cleaned up from the orchard floor at
the end of the picking season. Rotting
fruit is not only an invitation to disease but
attracts unwanted bird life.
Pest monitoring and management is an
ongoing job but planning ahead and
spraying on time will ensure damage is
minimised. Whenever possible, soft and
well-targeted chemicals should be used to
lower impact on beneficial insects within
A well-planned and implemented
summer plan for the orchard is just one
way of boosting the next-season harvest
take and there are plenty of equipment to
help get the jobs done.
