Overall, Delosperma nakurense is a fascinating plant that offers both ornamental and medicinal value and is easy to maintain.Light Requirements
Delosperma nakurense (Engl.) Herre prefer full sun or partial shade. When planted in full sun, it can tolerate several hours of direct sunlight. However, care should be taken to place the plant in a location where it is protected from intense afternoon sunlight and heat, especially in hot summer months.
Temperature Requirements
Delosperma nakurense (Engl.) Herre grow best in temperatures ranging from 18 to 25 degrees Celsius, but can also tolerate temperatures as low as 5 degrees Celsius. It is important to monitor the plant during frost or cold periods and provide protection, such as covering with a cloth.
Soil Requirements
The plant prefers well-draining, sandy soil with a pH range of 5.5 to 7.5. A soil mixture of sand, garden soil, and compost is ideal for growing Delosperma nakurense (Engl.) Herre. It's important to note that this plant is tolerant of drought and overwatering should be avoided as it can lead to root rot.
Cultivation Methods
Delosperma nakurense (Engl.) Herre, commonly known as Ice Plant, is a drought-tolerant plant that can be easily propagated from stem cuttings or seeds. The plant prefers well-drained soil and full sun exposure. It can be grown in containers or planted directly in the ground.
Watering Needs
Ice plants are adapted to dry conditions, and therefore, they require minimal watering. Inadequate water can cause wilting and poor growth, while overwatering can lead to root rot. Water the plant deeply once a week during the growing season and reduce watering in the winter.
Fertilization
Delosperma nakurense thrives in poor soil conditions and rarely requires fertilization. However, you can apply a balanced fertilizer during the active growing season to boost growth. Avoid over-fertilizing the plant as it can lead to weak growth and susceptibility to pests and diseases.
Pruning
Ice plants do not require pruning to maintain their shape or size. However, the plants can benefit from deadheading, which involves removing faded flowers to encourage more blooming. Prune the plant lightly in the early spring to remove old or dead stems and improve air circulation around the plant.
Propagation of Delosperma Nakurense
Delosperma nakurense is a fascinating succulent plant native to South Africa. Propagating this plant is relatively easy, and there are three primary propagation methods for the Delosperma nakurense:
1. Division:
Division is the quickest and most straightforward way of propagating the Delosperma nakurense. To do this, remove the plant from its current container and gently pull the plant apart, ensuring that each division has enough roots. Plant the divisions in well-draining soil, and water the new plants thoroughly.
2. Cuttings:
Another propagation method for Delosperma nakurense is through stem cuttings. Take a healthy leaf and remove it from the base of the plant. Allow the cutting to dry and callus for a day or two, then plant the cutting in well-draining soil. Keep the soil moist but not waterlogged and position the cutting in bright but indirect light. In a few weeks, the cutting should root and start to develop new foliage.
3. Seeds:
Delosperma nakurense can also be propagated by seeds. The seeds should be sown in a well-draining soil mixture consisting of coarse sand and perlite or vermiculite. Water lightly and cover the pot with a plastic bag to retain moisture. Keep the seedlings in a location that receives plenty of natural light or under fluorescent bulbs. In a few weeks, the seeds will germinate, and the new plants will develop.

Spider Mites: Spider mites are another common pest that might affect Delosperma nakurense. They are minuscule pests that feed on the plant’s sap, which can result in the discoloration of leaves and the shedding of flowers. To manage spider mites, it is essential to ensure that the plant is grown in a well-ventilated area to prevent overgrowth of the pests. Also, using an insecticidal soap or introducing natural predators, such as ladybugs and lacewings, can help to manage spider mites effectively.
Disease and pest management is essential for the optimal growth and development of Delosperma nakurense. By being cautious and following the above suggestions, you can successfully manage the diseases and pests that commonly affect this plant.
