I've recently had some alterations in my garden and instead of borders I have a couple of flags with pots on. I want to have a large pot with a Christmas tree growing in and have seen a gorgeous Lebanon Spruce Picea pungens Hoopsii and I was wondering if this would be suitable for pot growing. The tree is pot grown and is about 40cm high in a 14cm pot so quite small to begin with and I was wondering what size pot to buy for it. As I have spinal arthritis and find it difficult to lift heavy objects and also bend over, I don't want to keep re-potting it so really would like to put it in its permanent pot, so would be grateful if anyone could give me some ideas. Also what sort of pot would be best, I have large plastic pot which I want to use for something this year and was wondering if this would be OK?
