Spathiphyllum, perhaps better known by its common names single-leaf or leaf flag, is one of the most popular and probably most uncomplicated houseplants. When we talk about “uncomplicated”, this does not mean that the leaf requires no or only extremely little care (such as succulents). Instead, this means that Spathiphyllum is forgiving and quite robust.
How to properly repot a single leaf?
A single leaf should be repotted in spring by carefully removing the plant from the old container, loosening and checking roots, filling fresh substrate into a larger pot and then placing the plant in it. Drainage is important and the first fertilization takes place after six weeks.
Why annual repotting makes sense
If you want to do something good for your single leaf and give it optimal conditions for growth and flowering, it is best to repot it into a larger pot and into fresh substrate every one to two years. At some point the plant will certainly be fully grown and will no longer grow any larger. In this case, a larger planter is not necessary, but fresh soil is still necessary every year. If you cultivate your single leaf hydroponically, replace the top one or two centimeters of the substrate used. This measure is necessary because after a year the extremely hungry single leaf has absorbed all the nutrients in the substrate and the soil is now simply exhausted. In addition, older soil solidifies and compacts, which the roots don't particularly like. They prefer a loose and permeable substrate.
How to repot the leaf properly
With this repotting procedure you will always achieve good results:
- The ideal time is early spring between February and March.
- Carefully take the plant out of the old container.
- If necessary, run a sharp knife along the edge of the pot to loosen the root ball.
- Gently shake off any adhering soil and loosen the root ball with your fingers.
- Take a close look at the roots and especially check them for any rot.
- This could be an indication of overwatering.
- Now place the plant in a prepared pot with fresh substrate.
- Water them generously.
- Don't forget the drainage (€19.00 on Amazon) (for example in the form of expanded clay balls or pottery shards)!
The first fertilization can take place after about six weeks, provided you have used pre-fertilized soil.
Tip
Always remember that Spathiphyllum needs to be watered regularly, but under no circumstances should the moisture accumulate. It is preferable to use decalcified water or collected rainwater for watering.
