Signs of Cold Stress in Silverleaf Scorpionweed

Symptoms

Silverleaf Scorpionweed exhibits significant cold hardiness, yet winter temperatures should remain above 32℉. Should the temperature fall below this point, while immediate changes might not be apparent in winter, a reduction or complete absence of sprouting could occur in spring.

Solutions

During spring, eliminate any sections that have not germinated.

Signs of Heat Stress in Silverleaf Scorpionweed

Symptoms

Silverleaf Scorpionweed does not thrive in elevated temperatures. When the temperature surpasses 75℉, its development ceases, and its vulnerability to decay increases.

Solutions

Remove any sun-damaged and desiccated portions. Relocate the plant to an area offering protection from the midday and afternoon sun, or employ a shade cloth for cover. Irrigate the plant in the morning and evening to maintain soil moisture.
