I have our native oak and it does`nt look any bigger
now than it did 5 years ago!!!

The trick is to plant them in a big shallow tray or box, or in open
ground and let them grow on and put on some girth for a few years. If
you keep them confined from the start they will develop frustratingly
slowly. I learned the lesson too late.
If you plant them in open ground, put a flat stone a few inches down,
so a deep tap root doesn't develop.
