To delete all nodes from a TVirtualStringTree or its descendant use the Clear method (but note that the Clear method is virtual and can be overriden by some descendant. However, the implementer should keep the original purpose of this method, which is clearing the tree. If not, then it's just a wrong implementation in my view:

procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
begin
  VirtualStringTree1.Clear;
end;
