Plant Expert Reply:
When poinsettia cuttings have heat stress issues, the first course of action is to place them under cooler conditions. Poinsettia cutting should be grown at an 80-85degree day time temperature and a 70-75degree night time temperature. Keep the cuttings under a shade cloth until they form roots. Keep the humidity high and give the plants adequate moisture with out over saturating the soil with water. Soil that is too soggy will not allow the roots to form and will promote the growth of fungus gnats. Although the plants look wilted many will recover given the right conditions from here on out.
