Signs of Cold Stress in Sand dollar cactus
Symptoms
Sand dollar cactus flourishes in warm conditions and cannot withstand cold. Optimal growth occurs when temperatures exceed 68℉. 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. Promptly relocate the plant indoors to a warm spot, positioning it near a south-facing window for abundant light. If natural light is inadequate, provide artificial illumination.

Symptoms
In summer, Sand dollar cactus should be kept below 86℉. When temperatures surpass 95℉, the plant will stop growing, lose moisture, wilt, and be more vulnerable 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 watering until new root development is observed.
