Signs of Cold Stress in Organ pipe cactus
Symptoms
Organ pipe cactus flourishes in warm conditions and cannot withstand cold. Optimal growth occurs when temperatures exceed 65℉. In winter, maintain temperatures above 50℉. If the temperature drops below 40℉, the plant may weaken, droop, and be susceptible to root decay. Minor frost damage might not show immediate signs, but the plant will gradually decline after about a week.
Solutions
Remove any frost-damaged sections, checking for root rot. If roots are rotted, excise them, and the plant can be propagated from 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 supplementary illumination.

Symptoms
In summer, Organ pipe cactus should be maintained below 85℉. When temperatures surpass 95℉, the plant will stop growing, dehydrate, wilt, and be more prone to sun damage.
Solutions
Excise any sunburnt or decayed portions. Protect the plant from intense afternoon sun until it recovers and resumes growth. For plants with root decay, cease watering until new roots develop.
