A loose, organic-rich mix helps Spathiphyllum wallisii maintain healthy roots by balancing moisture retention, airflow, and gentle acidity.
Soil Texture
Loamy, Peaty, Organic-rich
Soil pH
Acidic (5.5–6.5), Slightly acidic (6.5–7.0)
Soil Drainage
Moist but well-drained
Native to tropical parts of Central and South America, Spathiphyllum wallisii grows on shaded forest floors where fallen plant material keeps the ground loose, rich, and lightly acidic. Those conditions explain why Peace Lily soil should feel moisture-retentive without becoming dense or stagnant.
Its roots prefer steady access to both water and air. A loamy, peaty, organic-rich substrate suits this balance because it holds even moisture while still draining well enough to leave small air spaces around the root zone. That structure supports healthy root function in typical indoor conditions.
A simple custom mix gives Spathiphyllum wallisii the balance of moisture retention and airflow it needs without becoming dense over time.
The finished blend should feel light, springy, and slightly crumbly, holding some moisture while excess water moves through without pooling.
A good target is 5.5–6.8 pH. This places the soil in the acidic to slightly acidic range, which suits Peace Lily and supports steady access to key nutrients.
Slight variation on either side is usually manageable, but strongly alkaline soil can reduce nutrient availability over time. Keeping the mix near mildly acidic conditions helps roots take up what they need more efficiently.
This species can react quickly when the root zone stays stressed for too long. Peace Lily often struggles more with stale, airless conditions than with a slightly imperfect mix.
Compacted soil: the surface dries slowly and the mix feels dense, so gently loosen only the top layer and plan to replace the medium if it no longer fluffs up.
Poor drainage: water sits in the container or the soil stays heavy for days, so check drainage holes and move the plant into a faster-draining setup if needed.
Salt buildup: a pale crust on the surface can point to mineral residue, so scrape off the top layer and refresh with clean mix.
Fungus gnats: frequent tiny flies around the pot often mean the surface stays damp too long, so let the top layer dry a bit more between checks and remove debris.

Yes. Drainage holes help excess water leave the container, which lowers the risk of stagnant conditions around the roots and keeps the potting mix more balanced over time.

Banana water can provide potassium and some nutrients that may support plant growth, but it is not a universal fix. Use it carefully and only when the plant actually shows signs of nutrient deficiency rather than as a routine treatment.
