I planted a brown turkey fig several weeks ago. I'm not sure of it's age, but it has just the stem and one branch and is maybe 3 ft tall. It was doing well, and had bright green leaves sprouting, but after two hard freezes the leaves turned brown and now, after weeks of warm weather, I see no growth. I bent the tip of the branch and it snapped off, totally dry, but I peeled away some bark and see another few inches of brown, dead branch and below that, about 8 inches from the ground level, green branch. Can I just cut away the brown part, or will it not heal from that?
