π§ How to Water
Water every 2-4 days, keeping soil evenly moist but never waterlogged. Check moisture by inserting your finger 2 cm into the soil β water when the top layer feels dry. Reduce watering in winter. Avoid wetting the leaves directly to minimize fungal disease risk.
βοΈ Lighting
Prefers full sun to partial shade β ideally 4-6 hours of direct sunlight daily. Indoors, place near south- or east-facing windows. Insufficient light reduces menthol content and diminishes the characteristic aroma.
