Spathiphyllum, perhaps better known by its trivial names single leaf or leaf flag, is one of the most popular and probably the most uncomplicated houseplants. If we are talking about "uncomplicated", this does not mean that the single sheet can do without or with very little care (such as succulents). Instead, it means that Spathiphyllum is very forgiving and quite robust.

Why annual repotting makes sense
If you want to do something good for your single leaf and give it the best possible conditions for growth and flowering, it is best to repot it into a larger pot and fresh substrate every one to two years. At some point the plant will certainly be fully grown and will not get any bigger. In this case, a larger planter is not necessary, but fresh soil is still necessary every year. If you are cultivating your syllable in hydroponics, swap out the top inch or two of the substrate you are using. 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 drained. Also, older soil hardens and compacts, which the roots don't like very much. They prefer a loose and permeable substrate.
This is how you repot the single leaf correctly
You will always achieve good results with this procedure when repotting:
- The ideal time is early spring between February and March.
- Carefully remove the plant from the old container.
- If necessary, run a sharp knife along the edge of the pot to loosen the root ball.
- Gently shake off any clinging 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 liberally.
- Don't forget the drainage (e.g. in the form of expanded clay pebbles or potsherds)!
The first fertilization can take place after about six weeks, provided you have used pre-fertilized soil.
tips
Always remember that Spathiphyllum needs to be watered regularly, but that the water shouldn't accumulate under any circumstances. When watering, use preferably decalcified water or collected rainwater.
