Grape vines arrived in Australia in 1788, and are now grown commercially in all territories and states. In fact, it is the fruit with the greatest production in the country. Grapevines need warmer weather to grow. Some sections of Australia get too cold; grapevines need 165 to 180 frost-free days to mature. But, the warmer regions of the country can house grapevines. There are close to 40 varieties of grapes, both red and white. Planting grapes in your backyard will provide you with yummy fruit for eating, canning and wine-making.
Choose a planting location in the full sun. Grapevines grow best if they are planted in the springtime.
Plant grapevines on a slope in Australia that faces away from cold winds. Grapes need to be protected from cold weather.
Check the drainage at the planting spot. Dig a hole and fill it halfway with water. Check to make sure the water drains out in a timely manner.
Loosen the top 12 inches of soil with a rototiller. Add sand or gravel to the local soil to amend it and make it drain better. Make the mixture a 50/50 ratio, combining it well.
Dig holes that are spaced 6 to 8 feet apart. This spacing will give Australian grape vines enough room to mature. Make the holes large enough to accommodate the root masses. Shallow holes are better for grape vines.
Pour the soil mixture into the bottom half of each hole. This will give the roots the best drainage possible.
Prune the root system to eliminate bent or broken roots. Gently spread the roots in each hole, centering the plants so they sit upright.
Cover the Australian grape vines with the soil mixture. Water lightly.
Surround each Australian grape vine with stakes to hold them in place. Pound each stake 2 feet into the ground with a hammer. Put a stake behind each plant for the best support.
Wind wire around the top of the first stake and run it to the next one, connecting all of the stakes in the row. When you get to the last one, tie off the wire. Do the same process again, this time putting the wire 6 inches to 1 foot below the first wire. If desired, make a third level of the trellis, as long as the bottom wire is 1 foot above the ground. This will protect the Australian grape vines and help air circulate around the plants.
Attach Australian grapevines to the trellis system. Tie them low when the plants are young, and move the wire to other layers as the vines grow. As they mature, they will naturally form around the support system.
