You might want to dig a much bigger hole, just in case the soil is compaced , youd loosen it up a bit. And maybe put a small fence or some shrubs at the base to stop the roots from being compacted from people walking too close.

Also make sure the hole is in a general square shape and not a circle, just so the roots dont grow round and round making some girdeled. If your in a hose pipe ban area a pipe to the roots might be an idea , ( i dont like them in public spaces in case someone pours root killer down! ).

Wish i had the space for one!

P.s if its a grafted root stock dont plant the root/stem union below the soil level or the roots will send shoots up!
