Chinese Elm
The Chinese elm also known as the Siberian elm tree is known for its resistance to the fatal Dutch Elm Disease.  Finding out if your tree is a Chinese elm is not as easy as one may think.  When these trees start dying off the city inspectors will often come and mark them for Dutch elm disease with a paint line around the tree.  And it obviously does not get Dutch Elm Disease.  So here is one of the easiest ways to know if you do indeed have a Chinese elm tree.
The bark is the place where you are going to want to focus on since the leaves are so similar to a slippery elm that most professionals could barely distinguish the two apart.  The trunk on the Other half will be much different.  It almost resembles a river birch in color.  The trunk will be less rough with the different colored spots.  They are in the orange range of color tones.  The picture to the left is a really good example of what they look like.
Now here is another great way to know you have a Chinese elm.  These trees have plenty of seeds and they grow like weeds.  A new tree will grow from nearly any soil possible.  So look for little trees popping out of everywhere and there is a good chance you have one of these trees nearby.
Chinese Elm are very disease tolerant.  They do not have many diseases that kill them completely.  They do have some minor leaf disease like the black spot shown on the right hand side of the page.  These trees do love water though and can get different rotting diseases that can be seen by defoliation on the crown of the tree.
Here are some things to look for in Chinese Elm trees:
  • Rotting on sections that are split
  • Black spots on leaves
  • Loss of leaves in sections.
