Ideal Temperature for Dollarjoint pricklypear

Dollarjoint pricklypear flourishes in warm conditions and cannot withstand cold. Optimal growth occurs when temperatures exceed 70℉. In winter, maintain temperatures above 50℉. If temperatures 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.

Remove any frost-damaged sections, checking for root rot. If roots are rotted, excise them, and the plant can be propagated 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 insufficient, consider using artificial grow lights.

In summer, Dollarjoint pricklypear should be kept below 100℉. When temperatures surpass 110℉, the plant's development will halt, it will dehydrate, wilt, and be more prone to sun damage.

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.
