My tangerine tree has damage to the branches in the bark and I don't know what it is from. The tree produces a lot of good fruit, I just don't know what's causing the bark damage. Is it something to worry about?
Spring Hill is central Florida, just north of Tampa on the Gulf Coast. We do get some freezing nights here. I wasn't sure what damage freeze could do besides hurting the fruit.
Besides the missing bark, have you seen any gumming, or a fungal caused encrustations of hyphae? If so the situation could be a more serious situation. - Millet
No I don't see anything that looks like gumming or any kind of fungus. The lesions in the bark don't seem raw, they are smooth and nothing odd seems to be growing on the tree anywhere. I know I have greasy spot on the leaves and some sooty black stuff on the tops of the leaves that I think are from aphids that just wipes off. I appreciate any input! Thanks a bunch.
Sometime check out Psorosis bark symptoms of Citrus. CCPP - Diseases Blind Pocket can cause the concavities seen in the wood in the first (left photo) image and the darkened, desiccated area seen in the second image (right photo). Jim
For further reading of Blind Pocket I believe there is mention of this disease and its affliction to Mandarins, Sweet Oranges and Lemons in the Leo J. Klotz Color Handbook of Citrus Diseases book. Should be listed in the Psorosis complex section of bark diseases in that soft cover publication from the University of California, Division of Agricultural Sciences. I am not saying that the problem with this Tangerine is due to Psorosis but by the symptoms shown in this tree from the two photos presented, an external Blind Pocket form, more so rather than an internal Concave Gum Disease causal agent, is a real possibility.
