Signs of Cold Stress in Key lime
Symptoms
Key lime favors warm conditions and cannot withstand low temperatures. It flourishes optimally when temperatures exceed 70℉. In winter, it must be maintained above 50℉. If the temperature drops below 32℉, leaves might lose their vibrant color. Following frost damage, the foliage progressively darkens to brown or black, and signs like wilting and drooping may appear.
Solutions
Remove the sections damaged by frost. Promptly relocate the plant indoors to a warm setting for protection against cold. Select a position near a south-facing window for the plant, ensuring abundant sunlight. Furthermore, refrain from placing the plant near heating units or air conditioning vents to prevent excessive air dryness.
Signs of Heat Stress in Key lime
Symptoms
In summer, Key lime should be kept below 100℉. When temperatures surpass 104℉, the leaves' color fades, and the plant becomes more prone to sunburn.
Solutions
Prune off the sun-scorched and desiccated portions. Transfer the plant to an area that offers shelter from the midday and afternoon sun. Irrigate the plant in the morning and evening to maintain soil moisture.
