The Spathiphyllum, also known as the Peace Lily, is a houseplant appreciated for its glossy dark green leaves and stunning white spathes. Native to the tropical forests of America, it is easy to grow and adapts well to low-light conditions. It can be easily propagated by division of clumps, allowing for the rapid production of multiple plants while preserving the characteristics of the mother plant. This is also an economical and rewarding method. Discover all our tips for propagating Spathiphyllum by division of clumps!
Why propagate Spathiphyllum?
Propagating Spathiphyllum has several advantages. It gives you the opportunity to obtain new plants without having to purchase them, while faithfully preserving the characteristics of the mother plant. It is also an effective way to control growth: a compact clump can limit root development, and division can revitalise the plant. Finally, it is an accessible and low-cost method, ideal for houseplant enthusiasts!
When to propagate Spathiphyllum?
The best time is spring or early summer, when the plant is in full growth and can better withstand the stress of division. However, if indoor conditions are favourable (temperature between 18°C and 24°C), it is also possible to intervene in summer. The important thing is to choose a time when the plant is vigorous, which will facilitate the recovery of each new plant.
The necessary materials
- Pots with drainage holes, slightly larger than each clump.
- A light and well-draining substrate (for example, a potting mix for green plants mixed with perlite or coconut fibre)
- A watering can
Practical steps for dividing Spathiphyllum
Here are the step-by-step instructions for successful division:
- Water the plant the day before to soften the clump and reduce water stress.
- Gently remove the Spathiphyllum from the pot by turning it upside down while supporting the base of the plant.
- Gently shake or crumble the clump to expose the roots and identify natural separation points.
- Separate the clumps, ensuring that each section has at least 3 or 4 leaves and a good root system.
- Replant each division in a pot, filling the bottom with substrate and then gently firming it around the roots.
- Water generously after repotting to encourage substrate adherence and minimise transplant stress.
- Place the new pots in indirect light, in a warm location protected from drafts.
After division: care and maintenance
Once repotted, the sections should be watered immediately to thoroughly moisten the roots. Position the new plants in a bright location, but out of direct sunlight, and at a stable temperature. Keep the substrate slightly moist, without excess, and be vigilant: a slight drooping of the leaves is not concerning, as long as new shoots appear. To encourage recovery, it is advisable to wait a few weeks before applying a moderate amount of fertiliser.
