Mexican mint has strong resistance to disease and is generally not prone to illnesses. However, it can be vulnerable to leaf spots when light and ventilation are poor or when it is overwatered. Its care level is considered easy, since it only needs regular watering and little else. Mexican mint is well suited for people who lack the time and energy to provide consistent care.
How to keep Plectranthus Amboinicus.
Light
The mexican mint prefers a balanced amount of light, flourishing with moderate sunlight while being able to tolerate stronger sun without harm. It comes from conditions of filtered light, which encourage healthy growth. However, too much or too little light can impede its development and cause it to wither.
Water
When the top 1 to 2 inches (2.5 or 5 cm) of the soil becomes dry, water Cuban Oregano. Apply 1 inch (2.5 cm) of water to the surrounding ground with a garden hose. Water the plant in the middle of the morning to give the saturated foliage enough time to dry before dark.
Humidity
This plant will thrive in moderate humidity, which is probably the level in your home. However, misting it a few times a week can be very beneficial. Make sure the room has good ventilation.
Temperature
The Mexican mint, native to tropical areas, thrives at temperatures between 68 and 100 °F (20 to 38 °C). In winter it should be kept no lower than 60 °F (15 °C) to prevent cold damage and no higher than 80 °F (27 °C) to avoid heat stress. In summer, it is better placed in partial shade to protect it from high temperatures.
Fertilizer
Mexican mint needs the most fertilizer during its active growth period, which takes place mainly in spring, summer, and early fall. Fertilization is needed to supply essential nutrients the soil may lack, supporting healthy root and stem growth and producing the attractive foliage that is a distinguishing feature of this plant.
Pruning
Trim the lowest two or three inches of the leaves and place the cutting in the water. Place the cup in a sunny safe spot outdoors or on a sunny windowsill indoors. Every two days, change the water. New root development should appear at the bottom of the cutting in two to four weeks.
Pot & Repot
When repotting Mexican mint, choose a pot 1–2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, ensuring that the root ball is slightly lower than the rim of the flower pot. Water thoroughly after repotting and place it in a warm spot with indirect sunlight.
