- Rotate the cup every few days for even growth toward light.
- Mist leaves occasionally to simulate natural humidity.
- Don’t hesitate to thin seedlings if too many sprout. Stronger ones will thrive.
- Keep your lemon plant indoors in cooler climates. In warm regions, it can move outdoors in a larger pot.
