We have two Nashi Pear Trees in our backyard which used to be absolutely stunning. For the last two years however possums have eaten every leaf and the trees have been completely bear. Even when one leaf pops up, it’s gone within 48 hours. The trees are still alive but without leaves in summer they look dead… How do we stop this? All other trees around our property and in our neighbours yards haven’t been touched by possums like this.
We’ve cut the trees back, have tried those fake owls, possum repellent from Bunnings and homemade, but nothing has helped!
