Signs of Heat Stress in California milkweed
Symptoms
In summer, California milkweed should be maintained below 75℉. When temperatures surpass 85℉, the plant's leaves might lighten, curl, suffer sunburn, 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 cloth. Water the plant in the morning and evening to maintain soil moisture.
