Q.Tree Sap Flowing From Grapefruit Tree
My grapefruit tree has a pinkish sap oozing from the branches next to the trunk and the grapefruit is turning yellow. Also, a couple of small branches have wilted leaves on them, so I cut them so that the other branches would not get infected. I really don’t know what the problem is and what to do to correct it. Your help and suggestions are appreciated.

A wound in the trunk of a citrus tree can lead to loose bark and oozing sap. The oozing sap could be a symptom of gummosis - a condition caused by infection by Phytophthora fungi. Gummosis does not cause rapid decline of the tree, but fruit production often decreases. Viral diseases cannot be cured, but providing good care helps.
On the other hand, oozing of sap on citrus is not all that uncommon. Many times there is no particular known cause that can be identified. The oozing frequently does not last very long, and clears up on it own without any noticeable harm to the tree.
