I'll apologize in advance because this may be a long one.
Last fall (2015) I helped (it was my intention anyway) a friend clear the area in and around her fig tree growing in a bush style. She likes things neat and tidy and she had mentioned before how she cuts back the stems and throws them away. I offered to help clean out the yard in exchange for some of the wood to try and root with the promise that if it worked I'd give her some plants the following spring. I did confirm with her that she wanted everything cut back. There were a lot of hollowed out stalks that were truly dead, but there were, of course, stalks from the current year with growth on them. This was in November, or maybe even later, but definitely after a frost and the leaves were crunchy. I took out the dead stalks and cut the current year stalks back to a foot off the ground and some near the fence taller than that. She usually does nothing at all, no pruning or winter protection, and the plant has returned for more than 20 years it's my understanding. Now that I think about it, she must have done whatever clearing out she did in the spring.
Just as a little more background she's offered me a piece of her plant to try to root over the last three years now. Early 2015 I had gone over and cut some canes to try to root. I realized later that I was trying to root dead wood. On May 25, 2015 (that's the date on my label) she told me that the tree was growing and if I came right away she knew I'd be able to get these to work. I chose three small growths and two of them rooted.
I've read and read about fig care and it was/is my understanding that the tree is only hardy to 20 degrees. Below that temperature with no protection the top will likely die out, but the plant will\may regrow from the roots.
Jump to late April of 2016. I've kept her informed that her cuttings have rooted and I'll have plenty of plants for her to give to friends or replant or do whatever she pleases with, but she doesn't want to take them yet. She told me that she thinks her plant is dead. Of course I don't want to believe that figuring it's just too cold outside for the plant to have started growing yet. I finally got a chance to go and look at the plant myself recently. Some of the bark is obviously dead, but the fat 2-inch bark/root, not sure which, horizontal growth on the ground is green when you scratch it. When I looked carefully, I do see just a few places where new shoots are coming off the branch.
I took a picture, but can't get it off my camera. It looks like there were two plants that had spread into a 4x10 patch. She doesn't know what variety of fig it is. Our weather has been unseasonably cold. We're expecting three days of overnights in the 40s next week. In April we had a couple days up into the 70s. Generally for the last month or so we've had 50-60 daytime temps and 40-50 nighttime temps. And over the winter in addition to our typical cold Chicago temperatures we had at least two days that hit -20.
Initially I wanted to wait and see what will happen with the plant, but with the weather still predicted to be so cold I'd just like to reach out and get some opinions. Do I need to be worried that I killed her plant? Any thoughts would be greatly appreciated.
