As your lemon plant grows, it will eventually outgrow the cup. Repot it into a larger container when:
- The roots are visible through the drainage holes.
- Growth appears stunted despite proper care.
Choose a pot that is 2–3 inches larger in diameter and use the same well-draining soil mix.
Planting a lemon seed in a cup is a simple and enjoyable way to bring nature indoors.
Not only does it provide a natural air freshener and mood booster, but it also serves as a beautiful, low-maintenance addition to your home.
