Signs of Cold Stress in Shiranji-tea
Symptoms
Shiranji-tea thrives in warmth and cannot withstand cold. Optimal growth occurs above 60℉. In winter, maintain temperatures above 50℉. Below 40℉, leaves may lose color. After frost, they progressively turn brown or black, potentially leading to wilting and drooping.
Solutions
Remove frost-damaged sections. Relocate the plant indoors to a warm area for protection. Position it near a south-facing window for sufficient light. Avoid placing it near heaters or AC vents to prevent air from becoming too dry.
