I recently purchased a tree from a local nursery. It was originally in a 15-20 gal pot.
The trunk of the tree was not centered in the pot. Instead its was an inch or two away from the edge. As a result, the root system has all grown to one side of the tree trunk. When the wind blows the tree I can see the root ball moving up and down on that rootless side.
My first and only remedy has been to stake the tree on that side to prevent movement. My hope is that this additional stability will allow it to grow roots on that weaker side. The stake is about 3 ft away and I used an old rubber hose where the twine wraps the tree.
What additional measures should I take to stabilize the tree and/or roots?
