You need a radically larger pot, or put it in the ground. Everything else sounds good. You could also thin out some of the pups.

ice cream, rajapuri, dwarf or tall orinoco, dwarf namwah is a good one but a little shorter than what you wanted. Saba is a very tall one that's shown some good hardiness down south. I can't mention a nursery on line that sells them since I'd get in trouble here! Not allowed to promote, etc. if you have a business.

I don't know if my wrapping will do, but I first covered all trunks with pipe insulation (there are only 3 but they are 4-5 feet tall). Then I packed bags of leaves around the whole plant, two large bags tall. Next I wrapped a tarp over the top, from front to back of the topmost bags. Another tarp was wrapped around the base (and it was 5 feet wide, so it covered much of the tarp hanging from front to back. Additional leaves were stuffed into any open spaces and then the whole thing was tied, around 4-5 times and over the top two times. I then braced the whole thing with a couple 2x4's. If this works I will make a frame to go around the plant next year, wrapped in plastic so I don't have to mess with bracing and tieing as much. If it doesn't I've still got my potted figs. ~Chills

I do my gardening in a zone 5/6. I have to protect all of the Macrophyllas if I'm going to get any flowers. I would bet that you shouldn't have too much trouble over the actual winter months. These plants can take the extremes of cold that you should be expecting. The real problem for you ( and me, too, actually) is the fluctuations. It's Luis' "ker plunks" that end up getting us. Dirr has said that he sees better flowering in a place like Cape Cod than he sees in Georgia, even though Georgia is a much higher zone. That's because, at Cape Cod, you don't get the ker plunks. The ocean, the native habitat of these Macrophyllas, keeps the temperature moderate. No ker plunks. Being relatively close to the ocean might save you somewhat. At least in many years. You don't need to worry so much about doing something before the first frost unless it happens like tomorrow or something. As long as the weather follows a moderate path into the winter, you wouldn't have any problem at all. I don't do anything here until after the frosts come. The real problem for you, I would bet, is next Spring. That's when the damage is likely to happen. Typical for us people away from the moderating ocean, just like interior Georgia, is for a nice long spell of warm weather in Spring, fooling the plants into thinking that it's all over, with the buds opening up, only to get zapped with the ker plunk that follows. If you want to take your chances and do a minimal amount of work maybe you should consider not doing anything elaborate over the winter, but be ready to run out in the Spring when we get that night or two of cold and cover the plants with sheets of plastic and/or some other insulating material. Nobody said it was going to be easy. Fun maybe, but not easy. Good luck. Hay
