Signs of Heat Stress in Arborvitae fern
Symptoms
In summer, Arborvitae fern should be maintained below 75℉. When temperatures surpass 80℉, the plant's foliage might lighten, curl, become prone to sun damage, and in severe instances, the whole plant could wilt and dry out.
Solutions
Remove any sun-damaged and desiccated portions. Relocate the plant to a spot offering protection from midday and afternoon sun, or use a shade covering. Water the plant in the morning and evening to maintain soil moisture.
