Hi George, I have successfully over wintered two eggplants bushes, one in the ground and one in a metal planter box. The later is the one I still have at the moment - it is the long, skinny, pinky-purple eggplant. I couldn't believe how many eggplants it produced this summer just gone. They look terrible all winter, just like the capsicum bushes I have over wintered, but come good in the spring. One of the presenters on 3CR's gardening show mentined that you don't touch them until spring is well and truly here, then you can trim them and tidy them up. Best of luck!
