Liverwort on Lawn Soil: Compaction and pH Fixes Eliminate the Need for Removal

Dark green hard growth on soil in several areas. Master Gardener said liverwort. Appeared last 3 years, spreading. Moss Kill ineffective. Asks removal before tilling?

Fix the Cause, Not the Symptom

1. Check pH—target 6.5–7. Adjust if needed.
2. Aerate 3–4" deep (till or core aerate). If tilling, spread thin leaves/compost first—some driven in, rest mixes into holes.

Algae/moss/liverwort = compacted soil. Check pH yearly.

Follow-Up: Remove First?

Don't remove. Loosening soil + pH correction makes it disappear. Incorporating adds organic matter. Near tree roots, repeat every few years.
