I have a small Fallglo Mandarin. Or actually...I used to. While inspecting plants I brought in yesterday since it got COLD last night, I noticed that this plant has died above the grafted point.
What I'd like to know is if there's a "usual" rootstock used with these plants. It was bought at a local nursery and originated in FL.
The picture shows the dead portion and the sucker growth at the bottom. If there is a usual rootstock and it's a decent type, I'll keep it, if not, I'll probably giver it away.
Thanks,
Barb
