Signs of Cold in Madagascar periwinkle
Symptoms
Madagascar periwinkle thrives in warmth and cannot withstand cold. It grows best when temperatures exceed 68℉. In winter, it needs to stay above 59℉. If the temperature drops below 50℉, leaves may lose their vibrant color. After frost, damage appears as browning or blackening, accompanied by wilting and drooping.
Solutions
Remove any parts damaged by frost. Promptly relocate the plant indoors to a warm area for protection from cold. Position the plant near a south-facing window to ensure sufficient light. Furthermore, avoid placing it near heating or air conditioning vents to prevent overly dry air.
