Signs of Cold Stress in Coastal Pricklypear
Symptoms
Coastal Pricklypear flourishes in warm conditions and cannot withstand cold. Optimal growth occurs when temperatures exceed 65℉. In winter, it must be maintained above 50℉. Should the temperature drop 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 frost-damaged sections, checking for root rot. If roots are rotted, excise them, and the plant can be propagated via cuttings. Promptly relocate indoors to a warm setting, positioning the plant near a south-facing window for ample light. If natural light is inadequate, provide supplementary illumination.

Solutions
Excise sunburnt and decayed portions. 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.
