Live Oak Decline After Tree Well Construction and Drought

Massive live oak in Georgetown shows dieback on outer limbs and top. Recent tree well construction added fill dirt. Drought ongoing. Sprinklers in well may not reach roots.

Primary Cause: Fill Dirt in Tree Well

Even a few inches of added soil within the dripline suffocates roots. Oaks are highly sensitive. Symptoms appear months to years later.

Secondary: Drought + Poor Watering

Roots are in top 3 feet, but fine roots concentrate in top inches. Sprinklers in the well only wet the fill, not the original root zone.

Action Plan

  1. Water correctly: 1 inch every 3 days over entire root zone (1.5x canopy spread). Use pan method.
  2. Remove fill if possible: Excavate to original grade within dripline.
  3. Fertilize: 10-10-10 at 1 lb/inch trunk diameter.
  4. Call state forester: Free on-site assessment (Texas Forest Service).

Tree wells must be at dripline with drainage away from trunk. Current well likely doomed the tree without intervention.
