Honeydew and Rockmelons
Production 
Ground preparation starts in February after the crop has finished
bearing fruit. The old plastic mulch and T- Tape trickle line is
lifted and the ground ripped and cultivated. New plastic mulch and
trickle tape is laid in the winter months, generally in August. The plastic mulch helps
to retain soil temperature and moisture, which in turn conserves water and controls weed growth. Planting occurs over a three month window, from late August to the middle of November.
The climate at St George is well suited to melon production. The warm, dry conditions ensure a firm textured melon with a bright flesh
colour, and high sugar levels. Our climate, coupled with the fact that we are the only horticulture enterprise in the area, also greatly reduces the presence of pests and disease in our crops, leading to minimal chemical usage.
Our seeds are bought from
a variety of companies and germinated by Withcott Seedlings. The
seedlings are planted by a team of people who sit on a machine called
a transplanter. Seedlings are used instead of seed to ensure the
crop establishes quickly despite the cool weather.
The crop takes about 8-12 weeks to mature, depending on the time
of year. Bees are used to pollinate the crop, in order to bear fruit.
Irrigation is computer controlled, ensuring watering occurs at optimum times
and efficiency. Plant samples are sent to a laboratory
regularly to determine crop nutrient levels. Any deficiencies are
rectified by applying specialised fertilisers through the irrigation
system.
Harvesting
Harvesting commences in November each year and finishes at the end
of January. Honeydews & rockmelons are hand picked from the
vine when they are naturally ripe. A team of about 20 pickers walk
behind a machine called a harvest-aid, which is a purpose built
truck. The pickers place each melon on an elevator in front of them,
which transports melons into the harvest-aid. Melons are then transferred
into plastic bins, each with a capacity of half a tonne. Tractors
take these bins to the receivals area of the packing shed.
Packing
These bins are stacked in an undercover area where cool, fresh water
is continuously sprayed over them to start the cooling process.
They are then tipped into a chlorinated water vat to begin the washing
and sorting process. This water vat helps to reduce the core temperature
of the melons, and ensures the melons are free from bacteria.
The melons are then brushed and dried. They pass over a sorting
table where any non-conforming melons are removed by a team of sorters.
The rockmelons then pass by a camera, which takes a photo of each
melon and records its size. A conveyor of plastic ‘fingers’
transports the melons and drops them into packing bins according
to size. One or two packers stand at each bin and place fruit into
cartons. There are two sizes of cartons to accommodate the 10 melon
sizes. Full cartons are then carried by a powered conveyor to the
pallet stacking area. Here, boxes of the same sized melon are stacked
on a pallet.
All pallets are barcoded so that product can be traced back to
the particular field and date of packing. Full pallets are transferred
to a cold room and forced air cooled to between 4 and 8°C to
preserve product quality and shelf life.
Dispatch
On average, three to four trucks leave the melon shed each day bo und for the major cities in Australia. These trucks are refrigerated and hold about 20 tonnes of rockmelons.
