Signs of Cold Stress in Poinsettia
Symptoms
Poinsettia favors warm conditions and cannot withstand cold. It flourishes optimally when temperatures exceed 60℉. In winter, maintain temperatures above 55℉. If the temperature drops below 50℉, foliage may lose vibrancy. Following frost damage, leaves progressively turn brown or black, and signs like wilting and drooping might appear.
Solutions
Remove any parts damaged by frost. Promptly relocate indoors to a warm setting for protection against cold. Position the plant near a south-facing window to ensure sufficient light. Furthermore, avoid placing it near heating units or AC vents to prevent excessive air dryness.
Signs of Heat Stress in Poinsettia
Symptoms
In summer, Poinsettia should be kept below 70℉. When temperatures surpass 75℉, leaf coloration fades, and the plant becomes more prone to sunburn.
Solutions
Prune off any sun-scorched and desiccated sections. Relocate the plant to an area offering shelter from the midday and afternoon sun. Irrigate the plant in the morning and evening to maintain soil moisture.
