You can’t stick those root balls back in the ground
If Irene pushed over a tree in your landscape, chances are it will never recover, so it is best that you remove it and replace it. Over the years, I have seen many home gardeners and arborists try to rescue toppled trees by bracing them. However, I have never seen full recoveries, even after the trees have been braced for several years. Shortly after the braces are removed, the trees begin leaning.
