Signs of Cold Stress in Macadamia nut
Symptoms
Macadamia nut favors warm conditions and cannot withstand low temperatures. It flourishes optimally when the temperature exceeds 59℉. In winter, it must be maintained above 50℉. If the temperature drops below 41℉, foliage may lose its vibrant color. Following frost damage, the leaves progressively turn brown or black, and signs like wilting and drooping might appear.
Solutions
Remove the sections affected by frost. Promptly relocate the plant indoors to a warm setting for protection from cold. Select a location near a south-facing window for the plant, ensuring abundant light. Furthermore, avoid positioning the plant near heating units or AC vents to prevent excessive air dryness.
Signs of Heat Stress in Macadamia nut
Symptoms
In summer, Macadamia nut should be kept below 77℉. When temperatures surpass 86℉, the leaves' color fades, and the plant becomes more prone to sun damage.
Solutions
Prune off the sun-scorched and desiccated portions. Relocate the plant to an area that offers protection from the intense midday and afternoon sun. Irrigate the plant in the morning and evening to maintain soil moisture.
