Light Requirements
Delosperma pachyrhizum L.Bolus needs full sun to partial shade to grow properly. It requires about 6 to 8 hours of direct sunlight for maximum growth. When grown in partial shade, ensure the plant does not receive more than 50% shade.
Soil Requirements
The soil should be well-draining with a pH range of 5.5 to 7.5. Delosperma pachyrhizum L.Bolus plants are versatile in their soil requirements and can grow in sandy, loamy or clay soils. However, the soil must be fertile to ensure adequate nutrient uptake by the plant.
Temperature Requirements
Delosperma pachyrhizum L.Bolus is drought-tolerant and can handle high temperatures as long as the soil is moist. It can thrive in a wide range of temperatures, from 50°F to 90°F (10°C to 32°C). However, it is important to keep in mind that low temperatures can harm the plant, and it may not tolerate frost or cold weather.
Cultivation
Delosperma pachyrhizum L.Bolus, also known as the thick root ice plant, is a succulent plant that is relatively easy to cultivate in warm and dry areas. To start, choose a location with well-draining soil and plenty of sunlight. If the soil is clayey, mix it with sand and perlite to improve the drainage. Prepare a shallow planting hole with a spacing of 8 to 12 inches between plants. Place the plant in the hole and cover the roots with well-draining soil. Water the plant until the soil is moist, but avoid overwatering, as the plant is susceptible to root rot.
Watering Needs
Despite its drought tolerance, Delosperma pachyrhizum L.Bolus requires regular watering during the establishment period, which can range from two to four weeks. Once the plant has formed a strong root system, reduce the watering to only when the top inch of soil is dry to the touch. In high temperatures or prolonged dry spells, increase the watering frequency. The plant has a shallow root system that can become damaged if watered too deeply or too frequently, so it's essential to water the plant slowly and deeply to promote root growth.
Fertilization
Delosperma pachyrhizum L.Bolus doesn't require a lot of fertilizer, but a light application of a balanced fertilizer during the growing season can boost its growth and overall health. Fertilize the plant once every four weeks using a slow-release fertilizer or a diluted liquid fertilizer. Be careful not to over-fertilize the plant, as this can result in excessive foliage growth and fewer flowers.
Pruning
Pruning is not mandatory for Delosperma pachyrhizum L.Bolus, but it can help maintain its shape and promote bushier growth. Pinch off the tips of the stems at the beginning of the growing season to encourage lateral growth. Deadheading the spent flowers can also prolong the blooming season and prevent the plant from self-seeding. Use sharp and sterile pruning shears to remove any damaged or diseased stems and leaves.
Propagation methods for Delosperma pachyrhizum L.Bolus plant
Delosperma pachyrhizum L.Bolus, commonly known as "Fragrant ice plant," is a succulent perennial plant that adapts well to arid environments. Propagation is an essential part of growing Delosperma pachyrhizum, and several methods can be employed to reproduce the plant. Here are some propagation methods:
Division
Dividing Delosperma pachyrhizum is an easy and effective way of propagating the plant. You can divide the plant after every two to three years when it becomes crowded or outgrows its container. It's best done in the spring season when new growth emerges.
To divide the plant, gently remove it from its container while preserving its roots. Divide the plant's clump into small sections and plant each segment in a container filled with well-draining soil. Keep the soil moist and place the containers in a bright, well-lit area.
Stem cuttings
Stem cuttings are another popular method of propagating Delosperma pachyrhizum. To propagate the plant, select a healthy stem from the existing plant and cut it using a sterilized utility knife or gardening shears. Make sure the stem is at least 4 inches long and has more than two leaves.
Remove the lower pair of leaves and dip the cut end of the stem in rooting hormone powder or gel. Plant the cutting in a container filled with well-draining soil, making sure that the cutting is well-anchored. Water the soil thoroughly and cover the container with a clear plastic bag to create a humid environment. Place the container in a bright, warm place, and wait for roots to form. Once the roots have formed, remove the plastic bag and keep the soil moist.
Seed propagation
Seed propagation is also possible with Delosperma pachyrhizum but requires a little patience and effort. It's best done in the early spring season when temperatures are warm.
To propagate Delosperma pachyrhizum through seed, prepare a seed tray filled with well-draining soil. Sow the seeds in the tray, barely covering them with soil. Water the soil thoroughly and cover the tray with a clear plastic lid. Place the tray in a warm, bright place and keep the soil moist.
The seeds usually germinate within two to three weeks. Once the seedlings have reached the right size for transplanting, remove them from the tray and plant them in separate containers or in your garden.
With proper care and attention, these propagation methods can yield beautiful and healthy Delosperma pachyrhizum plants!

The plant is drought tolerant and prefers full sun to partial shade. Like any other plant, it can be vulnerable to pests and diseases, which can compromise its growth and lead to poor yield. Here are some of the common diseases and pests that affect Delosperma pachyrhizum L.Bolus, and ways to manage them:
Diseases
Crown Rot: Crown rot is a fungal disease that affects the stem and roots of Delosperma pachyrhizum L.Bolus. It causes wilting and, in severe cases, the death of the plant. To manage this disease, it is essential to keep the soil well-drained to prevent waterlogging. Also, reduce the frequency of watering, and avoid over-fertilizing the plant. In case of an outbreak, remove and destroy the infected plant.
Leaf Spot: Leaf spot is a bacterial disease that causes circular brown spots on the leaves of the plant. It can also lead to the defoliation of the plant. A simple way to manage this disease is to avoid over-watering the plant, as wet leaves are a breeding ground for bacteria. You can also use a fungicide to manage an outbreak.
Pests
Spider Mites: Spider mites are tiny pests that suck the sap from the leaves of the plant, leaving them yellow and spotted. They are common in hot and dry weather conditions. To manage spider mites, spray the plant with water to increase humidity, which makes the environment unfavorable for their growth. You can also use insecticidal soap, neem oil, or other pesticides to control their population.
Scale Insects: Scale insects are pests that suck sap from the leaves, stems, and roots of the plant. They excrete a sugary substance that attracts ants and can lead to the growth of mold.
