I have just rescued two from being dumped, I have no idea what citrus
they are as the person doing the dumping was not the grower/owner. They
stand around 7' and are in very large heavy pots and have clearly been
outside for years, most of the dead and damaged parts I had to trim off
were caused by a montana which grown over them.

How much cold can they cope with if fleeced?
Would they be better in my unheated conservatory once winter comes?
Do they need regular repotting or is top dressing and feeding sufficiant?
If I can get them back to health can they be pruned back to get a better
shaped? I am concerned that if I do it now they would have few leaves
this winter.
As you may gather I have never grown citrus before!
