Signs of Heat Stress in Arctic lupine
Symptoms
Arctic lupine does not handle high temperatures well. When temperatures go above 75℉, its development ceases, and it becomes more prone to decay.
Solutions
Cut off any parts that are scorched and dried. Relocate the plant to a spot offering protection from the midday and afternoon sun, or use a shade cloth. Water the plant in the morning and evening to maintain soil moisture.
