Hi Cookie, yes I had one in a pot for about 18 months. It was bought as a pressie when we had the house up for sale and no way was I leaving it behind. I repotted it from the pot it came in, up to a large pot about 24 inches across. The only problem was keeping it sufficiently watered. Usual problem, when the compost drys out its a b****r to get it soaking up again. Worth a try though with a bigger pot, and maybe John Innes No 3. I would also put a slow release fertiliser in too, chicken pellets or blood, fish and bone meal. Best of luck.
