I could not view your photo link, but suggest you not do any pruning this time of year. Pears can be ‘leggy’ and often ‘shoot for the moon,’ but like most deciduous (dropping their leaves each year) fruit trees, they’re best pruned while dormant (leaves off during winter/ early spring).

My basic pruning instructions would have you envision the tree in the ground at it’s current ‘soil level’ (‘shorter,’ as if you’d planted the pot). Pruning requires a ‘vision’ of how you want the tree to look, then basically removing everything else. Again, you can safely do this while it’s leaves are off and it’s energy is stored in the roots, as opposed to the leaves.

It’s most important this tree get a permanent home… which will allow it’s roots to store sufficient energy to put out ‘desired growth’ after being pruned. Actually, while potted, pruning it fairly severely when dormant will leave less ‘tree to feed’ come spring, and shouldn’t do it any harm.

You might try again posting some photos here… but as mentioned, I’d try hardest to find it a permanent home in the ground
