Signs of Cold Stress in Teddy bear cholla
Symptoms
Teddy bear cholla flourishes in warm conditions and cannot withstand cold. Optimal growth occurs when temperatures exceed 70℉. In winter, maintain temperatures above 50℉. If the temperature drops below 32℉, 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 frost-damaged sections, checking for root rot. If roots are rotted, trim them and consider propagating new plants from cuttings. Relocate the plant indoors to a warm spot immediately, positioning it near a south-facing window for ample light. Supplement with artificial lighting if natural light is insufficient.

Symptoms
In summer, Teddy bear cholla should be kept below 90℉. When temperatures surpass 100℉, the plant will stop growing, lose moisture, 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 rot, cease irrigation until new roots develop.
