Loblolly Pine Decline: Soil Testing Is the First Step

The Case

Two loblolly pines in an unknown location show no green after a year of care. Owner tried iron; no improvement.

Root‑Zone Investigation

Yellowing with no green suggests root dysfunction—compacted soil, poor drainage, pH imbalance, or nutrient deficiency.

Action Plan

1. Collect soil samples from the root zone (6–12″ deep).
2. Submit to your county Extension office for nutrient and pH analysis (often free).
3. Check trunk base for mechanical injury (mower, string trimmer).
4. Ensure soil is moist but not waterlogged.

Why Guessing Fails

Without a soil test, fertilizer may not be absorbed if pH is off. The test tells exactly what’s needed.
