Requirements for Growing Purple Shamrock in Any Home
While growing indoors, make sure it gets at least 2-3 hours of direct sunlight on daily basis. Place the pot by a window that gets bright indirect light on most parts of the day.
Rotate the plant frequently so every part receives even light exposure. Remember, lack of light can cause stunted growth.
Full-grown shamrock plants can withstand some drought, but be vigilant about watering while the plant is young. Water when the topsoil feels a bit dry to touch. During dormancy in winters, water lightly about every 2-3 weeks.
Note: Never let the soil dry out completely as it will make the plant wilt.
Temperature and Humidity
Purple shamrock prefers a temperature between 60-80 F. The plant can endure nighttime temperature down to 50 F. Keep it away from air-conditioners, heaters, and drafts as they can harm the leaves. Moderate humidity is perfect for this plant.
