How to Propagate Peace lily plant?

Propagate Time: Spring, Early spring, Late spring

Choose a mature and healthy Spathiphyllum wallisii with numerous shoots or crowns. This ensures that each division you create has a stronger chance of developing into a robust plant.

Gently remove the plant from its pot, being cautious not to damage its root system. Loosen the soil around the roots to reveal the natural divisions.

Using a sterilized knife or shears, cut the crowns apart at the base, ensuring each section has roots attached. Aim for a clean cut to minimize trauma to the plant.

How to Repot Peace lily plant?

Repotting frequency: Every 2-3 years

Spathiphyllum wallisii usually requires repotting when you notice roots are growing through the drainage holes, or the soil is drying out more quickly than usual. Spring and early summer are ideal times for repotting as the plant enters its active growth phase, allowing it to adjust more easily to the new pot and soil.

Select a pot that is just one size larger than the current one, to avoid excess soil that retains too much water. Ensure it has drainage holes to prevent waterlogging, which can lead to root rot. The right pot helps maintain proper moisture levels and supports healthy root growth.

Opt for a well-draining potting mix rich in organic matter. A slightly acidic to neutral pH is best, with added perlite or orchid bark to enhance aeration and drainage. This type of soil minimizes overwatering risks and promotes healthy root development.
