Eucalyptus Cinerea in the South East US

[jbw]

A long-time customer of mine has a Euc. Cinerea which is ~32" dbh. Deadwood has been accumulating over the years and has been pruned accordingly.

Last week all of the bark fell off in huge sheets. I realize that the tree exfoliates the bark periodically, but does this happen all at once up to a height of 20'??

The tree is in a protected area and has been in its location for ~50 yrs. The pool backflow washout is 20' from the base of the tree; could this be affecting the Euc?? There are other trees and plantings in the area that aren't showing any signs from the discharge.

Any advice would be appreciated.

I can't answer your question but chlorine is toxic to plants.

I should have specified that the pool is salt water. Also, the tree is probably 6' above sea level and 300 yds from the marsh (brackish, tidal).

Silver dollar euc..Nice trees.Well.....A few pics would help.Has the sluffed bark exposed the cambium?Any sign of discolored/burned appearing leaves,dying twigs or branches.?
If yes,then how long has the pool been there.Water will migrate via gravity,and also capillary action.... will gravitate to dryer soil.Salt prevents the tree from absorbing water efficiently, forcing it to use more energy to hydrate itself and further weakening the tree.
Just shooting from the hip...So, if the tree appears healthy,then the peeling bark ''may'' be a normal function,or a sign of something more drastic.Best I can do.....

We don't have any Eucs around here so I have no idea. If a tree looses it's bark in these parts we look for a lightning strike.

Quick changes in temperatures are stressful for the eucalyptus especially in the weaker trees. Temperature tolerance ranges generally between 15 to 100 degrees F.
Last winter SC had nights on the lows 20 and when to the 55 degrees F at day time. if the euc was weak, now he might just be dying from temperature changes stress.
quick question what was the tree sap flow when you inspected the tree? was dry or shiny under the rest of the bark?
