What happened with your peach tree ? I bought one from homebase a short while back now (not patio - it's about 7ft tall), and took a chance planting it out in the ground. I'm in NE Scotland !!! same as you , the stem is green underneath, and when planted I trimmed the dead and twiggy bits of stem off, but so far no life whatsoever. Very disappointing. Though I remain ever hopeful, as the fruit trees were just 2 for £20 quid, and the plum is going great guns, buds all over the stems fit to burst ......
