Yellow Patches After Organica Lawn Booster: Aeration Side Effect?

Homeowner on Organica 4-step, applied Lawn Booster last week. Aerated + overseeded weeks ago. Yellow patches appearing. Location unknown (assumed cool region).

Likely causes:

• Cool/damp weather + diligent seed watering = fungal risk
• Aeration breaks fungal networks (mycorrhizae) → temporary nutrient disruption
• New seedlings sensitive to any stress

Aeration science (Jeff Lowenfels): Only plug-aerate lawns *lacking* healthy soil food web (new sod, chemically treated, poor drainage). Established organic lawns *lose* fungal networks from aeration. Earthworms hate it too.

When aeration helps: New seed/sod on rototilled soil, recent chemical history, compaction/drainage issues. Every 3–4 years max.

Next: Confirm location, grass type, yellow pattern. Organica is quality — yellow likely cultural, not product.
