Understanding the Watering Needs of Ice Plants
Ice plants (Lampranthus spp.) need adequate water during the growing season but can survive long periods of drought with reduced watering needs. Their thick, fleshy leaves store water, enabling them to adapt to arid conditions [ Lithops ] . However during periods of active growth, ice plants benefit from regular water to maintain healthy foliage and abundant flowering.
The fleshy storage tissues of ice plants allow for some forgiveness on the timing of watering. Ice plants can go for up to two weeks without watering during the spring and summer before their leaves begin to wilt and drop. However, if left in a dry state for more than four to six weeks, plants can become permanently stunted.
During the spring and summer growth period, water ice plants deeply once every 7 to 14 days to maintain well hydrated but not soggy soil conditions. Reduce watering to once a month or less in cooler months with milder temperatures when growth slows down. Resume normal watering frequency at the start of the next active growing season.

Factors to Consider in Determining the Watering Frequency
Many factors influence how often ice plants need water. Soil type, temperature, humidity, sunlight exposure,the season, and the plant’s size and variety all determine their water requirements.
Soil type is a primary consideration. Sandy soils drain quickly and hold little moisture,so ice plants in sandy soils typically need to be watered more frequently.Clay soils retain moisture for longer periods,so ice plants in clay soil may only need watering once every 2 to 3 weeks.
Temperature also impacts ice plants’ water needs.During warmer periods whentemperatures exceed 80°F, ice plants can lose moisture quickly through their leaves.Watering every 5 to 7 days may be necessary during these hot http://seasons.In|seasons.In cooler fall and winter months with less evapotranspiration,ice plants may only need water once every 2 to 4 weeks.
Plants receive more sunlight exposure tend to dry out faster,requiring more frequent irrigation.Those planted in partially shaded areas tend to have lower water needs.
Plant size also matters. Larger,more established ice plants have deeper roots that can access soil moisture from a greater depth. They often only need water every 7 to 14 days,while younger plants may need water every 3 to 7 days.
The specific variety of ice plant also influences its water requirements.Some varieties like
Delosperma cooperi are more drought-tolerant and need less frequent watering.
Best Practices for Watering Ice Plants
During the main growing season from spring through summer, aim to water ice plants deeplyonce every 7 to 14 days depending on temperature and moisture conditions.
On watering days, soak the soil thoroughly until water drains from the drainage holes.This deep watering ensures moisture penetrates down to the plant’s roots.Using a soak hose or drip irrigation system can make the process easier and more efficient.
However, avoid leaving standing water around the plants for long periods as this canpromote root rot. Allow the top 1 to 2 inches of soil to dry out between waterings.
During the cooler fall and winter months with milder temperatures,ice plants enter a semi-dormant state and require less frequent watering. Once a month watering maybe sufficient to keep the soil slightly moist.
For container-grown plants, check the moisture level by feeling 1 to 2 inches below thesurface.Water only when the soil starts to feel dry. Make sure there are adequate drainage holes at the bottom of the pot to avoid overwatering.
In colder regions where ice plants are grown as annuals, stop wateringcompletely once nighttime temperatures fall consistently below 50°F. The plants will die backbut reemerge in spring once temperatures rise again.
Signs of Overwatering and Underwatering Ice Plants
Overwatering ice plants can cause several visible issues:
Yellowing leaves as the roots cannot get enough oxygen due to excess water.The leaf tissue starts to break down and turns yellow.
Brown leaf tips and edges. Brown spots and dieback of leaf margins indicate the tissues are rotting due to lack of oxygen.
Rotting and mushy stems that collapse easily. The stems rot where they contact the moist soil.
Algae growth on the soil surface that proliferates under continuously wet conditions.
Fungus gnats and mosquito larvae that feed on the roots of ice plants kept too wet.
Underwatering ice plants results in different symptoms:
Wrinkled, limp leaves that appear wilted as the plant struggles with lack of moisture
Leaves take on a purplish cast as anthocyanins develop under drought stress
Plant exhibits slow or stunted growth due to lack of sufficient water
Stems may become hard and woody over time in response to dry conditions
Plant produces fewer flowers and seeds under drought stress
To remedy overwatering, allow the soil to dry out fully between waterings. For underwatering,increase watering frequency and amount to restore moisture to the soil. Consistent watering at the appropriate frequency based on your soil type and local conditions is key to raising healthy ice plants.
