I took some metal plant supports a friend of a friend gave us. I also took the familiar hardware cloth and florist wire from the indoor plant project. I placed four of the plant supports around the fig and drove them deep into the ground with a sledge hammer. I then took the hardware cloth and florist wire and created a low cage around the base of the fig tree. I only had enough hardware cloth for the two longest sides. The two other sides I created with multiple rows of florist wire. I also tied a line of wire around the top of the supports to add more strength to the whole structure. I then stuffed this cage with leftover straw from the fall decorations and some oak leaves from the yard. Hopefully this adds enough protection and insulation from the elements that the fig will start out bigger in the spring.
I did drive the four plant supports rather deep. And that is OK as I do not plan to remove these for a long time. While I do plan to remove the insulating straw and leaves in the spring, these metal posts will serve as great supports for a tall covering of bird netting come summer.
