First Paragraph: Succulent shoots and flower clusters may be killed by temperatures below 31 degrees F. If warm weather and rapid growth have immediately preceded a frost, some killing of rapidly growing shoots is likely to occur at 30 degrees F; but if the temperatures are not lower than 30 degrees F and are of short duration and occur in periods of cool weather, damage is slight. Temperatures of 26 degrees F or lower for a few hours will kill all green shoots, flower clusters, and even buds that are partly open.
