Hops like to grow up, straight up, and up. To get the best harvest they are generally grown up strings supported on a tall trellis. Recommendations are that the optimal height for the trellis is 5.5m, which needs some pretty long poles, at least 7m in our case. Clearly getting poles this big and heavy requires some heavy machinery, serious muscle or some smarts.
We hired a dingo for a weekend to dig the holes 1-1.5m in our clay soil. By this stage the rains had well and truly made an impact and the ground was very muddy. The dingo got bogged, the car nearly got bogged and even the tractor came close. After an exhausting but ultimately successful weekend we got our holes dug.
