Jerusalem Artichoke is NOT Deer Proof
(Central City, KY)
Sadly - Jerusalem Artichoke is NOT Deer Proof. The deer wait until the plant (which is just a sunflower) is 18-24" tall (which is when the mother tubers has expelled all its energy) and then they eat the tops off the plant, killing it before it can make new tubers. I had a milk crate full of tubers planted and the deer killed all of them. And my sunflowers.
