Question
Can I save my giant 30 year old bearing Mulberry Tree.  Last year, this main shade tree in our front had several branches that did not leaf out and bark was coming loose in several areas.  I found wood ants but after cutting off several dead branches, I noticed small holes all in the limbs.  I was told that it was bores.  This Mulberry Tree is about 40 feet tall with several large trunks going up from the ground.  It is starting to leaf out now but only on one side.  The other half of the tree looks to be dead; no leaves sprouting.  The bark comes loose from the limbs, cracks, then falls off.....dead limbs.   Is there anything that I can do to save the half of the tree that looks healthy at this time?  Thank you for your time and help ASAP.  We hate to loose it as we have grown it from a small sampling over 30 years.  Sincerely....Don Harmes

Answer
I would treat the tree with an insecticide called Bayer Advanced Tree and Shrub Insect control. This is applied to the soil and the roots take it into the trunk killing the borers in the wood. Borers attack trees under stress so i would also fertilize the tree with 10-10-10 fertilizer at the rate of 1 lb per inch of trunk diameter scattered around the tree and watered in good. Here is a web link to more information on Bayer Advanced.
