My multi-trunk mimosa tree is exuding sap(golden color). In addition, the bark has many long seperations which appears like stretch marks. Also, near the area where the sap in coming out the tree it has a hole in what appears to be the starting of a new branch that quit growing. Upon further inspection there is alot of branches we pruned and the ends have holes. Overall, the tree looks fine. Help, is my tree ok or sick? Thankyou, for your time and effort on this matter.

The presence of sap oozing from trees is usually a sign of some sort of stress. The stress can be coming from insect damage, disease problem and extremes of climate, such as heat. If it is a response to heat, the oozing will subside on its own. The pruning injuries may have been entry areas for insect or disease problems. Signs of an infested tree include round pits in tree bark, oozing sap, accumulation of sawdust (from larvae boring), and round exit holes. I really can't diagnose the problem without seeing it, but the above information should help you determine whether the sap is a result of climate, insect infestation or disease.

Best wishes with your mimosa!
