Signs of Heat Stress in Prostrate knotweed
Symptoms
In summer, Prostrate knotweed should be maintained below 75℉. When temperatures exceed 85℉, the plant's leaves might lighten, curl, become prone to sunburn, and in severe cases, the whole plant could wilt and dry out.

Remove any sun-damaged and desiccated portions. Relocate the plant to a spot offering protection from midday and afternoon sun, or use a shade cloth. Water the plant in the morning and evening to maintain soil moisture.
