Signs of Cold Stress in Chalk Lettuce
Symptoms
Chalk Lettuce flourishes in warm conditions and cannot withstand cold. Optimal growth occurs when temperatures exceed 60℉. In winter, maintain temperatures above 50℉. If temperatures drop below 40℉, the plant may weaken, droop, and become susceptible to root decay. Minor frost damage might not show immediate signs, but the plant will progressively decline after about a week.
Solutions
Remove any parts damaged by frost, checking for root rot. If roots are rotted, trim them and propagate the plant via cuttings. Relocate the plant indoors to a warm spot immediately, positioning it near a south-facing window for ample light. If natural light is insufficient, provide artificial illumination.
Signs of Heat Stress in Chalk Lettuce
Symptoms
In summer, Chalk Lettuce should be kept below 75℉. When temperatures surpass 85℉, the plant will stop growing, lose moisture, wilt, and be more prone to sun damage.
Solutions
Discard any sunburnt or decayed sections. Protect the plant from direct afternoon sun until it recovers and resumes growth. For plants with root rot, cease watering until new roots start to form.
