How do I get my tree to stand up straight again? It was pushed
by a hurricane.

If the tree is crooked from being pushed by strong winds, you can carefully push it back to straight and stake it or guy it to keep it vertical. Do not stake it tightly, it should be able to move slightly. Although, be careful to not use wire as it will cut into tree. After about a year, remove the stakes and guys.
