Signs of Heat Stress in Australian tree fern
Symptoms
In summer, Australian tree fern should be kept below 75℉. When temperatures surpass 90℉, the plant's foliage may lighten, curl, and become more prone to sun damage.
Solutions
Remove any sun-damaged or desiccated portions. Relocate the plant to an area offering protection from intense midday and afternoon sun, or use a shade cloth. Water the plant in the morning and evening to maintain soil moisture.
