Question
I have about 30 sesanqua as a hedge around yard. Recently, whole limbs are
dying- I've had soak hoses out during drought- Could it be a fungus? There
are no insects- they are about 10 yrs old. What about a wilt? Can I spray with
something to cover several possible problems? HELP- they would be so
expensive to replace.

Answer
There could be several reasons for the dying branches.  Even though you have soaker hoses, in a severe drought, the plants are still not getting enough water.  It is doubtful that a root rot or wilt disease is present in the dry weather, especailly if the dying branches are on this plant and then on one some distance away.  Check the affected branches to see if they are still alive by scratching gently with a pocket knife.  If you see green tissue underneath the bark, the limb is still alive and may come back out, even next year.  If you see brown tissue underneath the bark, the branch is truly dead and should be removed from the plant.  I would also look for cracks or splits in the bark near the soil line.  If you see this, it will be cold injury from last winter.  We tend to see cold injury more often during times of dry weather during the fall and winter.  I would keep the water to the plants and fertilize lightly this fall.  Hopefully, with a change in weather patterns the plants will stop dying off.  Good Luck.
