I have a similar pear tree it is a cordon, I bought it by accident along with my other fruit trees 3 years ago,after I planted it along with the others I realised it was not the usual tree shape and found the error in the paperwork. I couldn't return it as I had planted it .
I took it out a few months later when it was in full green and pot planted it and replaced it with the right one.
We got pears from it the second year and we had moved it when it had small fruit on.
We have moved this plant all over,we planted it in the garden at home,then I changed my mind, it went back in the pot, then it got planted on the second lottie when it was growing, I still can't make up my mind what to do with it. Right now it is in a spot that is temporary and it might get shifted this weekend back to a pot again.
It is the wrong time to move it but it is needs must I am afraid.
It has been loaded with blossom this year and has loads of tiny pears on.
This tree is actually very nice, it is in excellent health, a lovely shape and seems very tough.
With all it's travels it produced fruit after I had it 1 year and it was bought as a 2 year old.
Just a ramble for info. XX Jeannine
