Water Requirements for an Ice Plant

An ice plant (Delosperma nubigerum) is a succulent plant that resists drought by storing water in its stem, leaves or roots. Ice plants tolerate poor soil as long as it is well-draining, loose and porous. The succulent requires full sunlight, six to eight hours daily. Ice plants are an attractive landscaping feature when displayed in a rock garden, but the plant can get out of control and crowd out more desirable vegetation.

Dry, arid conditions exist when the soil receives rain but is quick draining, making it dry to a depth of 12 inches. Water the ice plant deeply every seven to 10 days while taking into account any rainfall or especially dry or light climate conditions. Water the soil to a depth of at least 7 to 12 inches so the root ball is completely soaked. Inadequate watering will result in the plant withering and dying. If wilting is observed, the plant needs water. Too much water too frequently will block oxygen to the root system of the ice plant and will cause root or stem rot, withering and dying. Do not water the ice plant before a freeze since the influx of water could cause the plant to freeze and die. It is necessary to monitor the condition of the plant from day to day.

Normal conditions exist when the soil receives rain, the climate is more temperate, and the soil is not as well-draining. The ice plant generally likes 1 inch of water per week during the growth period. Do not water the plant this often except during the growth period,as it could cause the plant to develop root or stem rot leading to the death of plant. Water ice plants weekly and deeply for the first year after they are set in the soil. Apply less water the second year, while maintaining a watchful eye on the condition of the ice plant.

Water the ice plant late in the day to alleviate stress to the plant, but early enough to allow the leaves to dry before nightfall. This is necessary to protect the plant from fungal infection.
