Lilac Branch Dieback: Investigate Bark Damage and Water

8-year-old transplanted lilac, flowered little, fall leaf dry/curl/die, whole branches dying, recurring in spring. Sevin didn't help.

Investigation

Check dying branches for loose bark. Multiple branches affected suggests root/trunk issue. Don't overlook drought—deep soak if dry/hot/windy (hose at drip line 2-3 hrs per area).

Next Steps

Consult local garden center/nursery. Sevin is insecticide—won't help if not insect-related. Professional examination needed for accurate diagnosis.
