Signs of Heat Stress in Japanese morning glory
Symptoms
In summer, Japanese morning glory should be kept below 75℉. When temperatures surpass 85℉, the plant's leaves might lighten, curl, become prone to sunburn, and in severe instances, the entire plant could wilt and dry out.
Solutions
Prune off any sunburned and desiccated portions. Relocate the plant to a spot offering protection from the midday and afternoon sun, or use a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
