I planted a new Mulberry tree in my yard this spring. It was planted when it was about 4 inches tall. It's just now taking off good and a few days ago I spotted a rabbit chewing on one of the few leafs it has grown.
I purchased this from Amazon. It comes as 7 plastic panels that you can clip together to fit the diameter and height you need. I used landscape pins to secure it to the ground. I used 4 of the 7 panels and it is very sturdy.
The rabbits will have to live on the clover in my lawn instead.
$18.95 on Amazon.......
