Once established, the plant is drought-tolerant and requires little water, making it a good choice for low-maintenance gardens. However, it cannot tolerate freezing temperatures and should be protected during winter months.
Light Requirements
Mesembryanthemum speciosum Haw. requires full sunlight exposure for optimal growth and development. It cannot withstand shady conditions as it is adapted to living in areas with high exposure to sunlight.
Temperature Requirements
The plant grows best in warm environments with average temperatures ranging between 20-30 °C (68-86 °F). Temperatures below 10 °C (50 °F) can be detrimental to the plant's growth and survival. Therefore, it is important to keep the plant in a warm environment all year round.
Soil Requirements
The plant prefers well-draining, sandy soils with a pH range of 6.0-7.0. The soil should be rich in organic matter and have good water holding capacity. Overwatering should be avoided as it can lead to root rot. Additionally, the plant is highly sensitive to salts and therefore requires careful soil management to avoid accumulation of salts.
Cultivation Methods
Mesembryanthemum speciosum Haw. is a drought-tolerant plant that is widely used in landscaping. To cultivate this plant, it is advisable to plant it in well-drained soil. The soil should be moderately fertile and should have a slightly acidic pH.
The plant should be exposed to direct sunlight, at least for part of the day. In colder climates, the plant should be grown in a greenhouse or indoors.
Watering Needs
Mesembryanthemum speciosum Haw. is a drought-resistant plant and does not require a lot of water. Overwatering could lead to root rot and other plant diseases. It is advisable to water the plant once a week, especially during the growing season.
The soil should be allowed to dry out between watering sessions. During the winter months, the plant can survive on little to no water.
Fertilization
Mesembryanthemum speciosum Haw. does not require a lot of fertilization. However, it is essential to provide the plant with the necessary nutrients to ensure healthy growth.
An all-purpose fertilizer can be applied in the spring, at the beginning of the growing season. It is advisable to use a slow-release fertilizer to avoid overfeeding the plant.
Pruning
Mesembryanthemum speciosum Haw. does not require a lot of pruning. However, if the plant becomes too leggy or out of shape, it is advisable to trim it back.
Pruning should only be done in the early spring before the growing season begins. This will allow the plant to recover from any damages caused by trimming.
Propagation of Mesembryanthemum speciosum Haw.
There are several methods to propagate Mesembryanthemum speciosum Haw.
Seed Propagation
One of the most common methods of propagating Mesembryanthemum speciosum Haw. is through seed propagation.
The best time to sow the seeds is in the spring or early summer, as the plant needs warmth and light to germinate. Before sowing, the seeds can be soaked in warm water for several hours to soften the seed coat and facilitate germination.
The seeds should be sown on top of well-draining soil, covered lightly with a thin layer of soil, and kept moist until they germinate. It takes approximately two to three weeks for the seeds to germinate.
Division
Mesembryanthemum speciosum Haw. can also be propagated through division. This method involves dividing the plant into smaller sections and planting them in individual pots or in the ground.
The best time to divide the plant is in the spring when the plant is actively growing. Care should be taken to ensure that each division has roots and shoots, and the plant should be watered thoroughly after division.
Cuttings
Mesembryanthemum speciosum Haw. can also be propagated through stem cuttings.
The cuttings should be taken in the late spring or early summer from the current year's growth. The cuttings should be at least 5-8 cm long and should be cut just below a leaf node. The lower leaves should be removed, and the cutting should be allowed to callus for several days before planting.
The cuttings should be planted in a well-draining soil mix and kept moist until rooting occurs. It takes approximately two to three weeks for the cuttings to root.
Disease and Pest Management of Mesembryanthemum speciosum Haw.

Common Pests
Like other succulent plants, Mesembryanthemum speciosum is prone to infestations by mealybugs, spider mites, and scale insects. Mealybugs are small, white, cotton-like insects that feed on the plant's sap and can cause stunted growth and discoloration of the leaves. Spider mites are tiny, red, or black pests that pierce the plant's tissue and feed on its sap, causing it to wilt and die. Scale insects are small, immobile insects that attach themselves to the plant's stem and feed on its sap, causing yellowing and stunted growth of the leaves.
Management of Pests and Diseases
To manage pests and diseases on Mesembryanthemum speciosum, it is important to regularly inspect the plant for any signs of infestation or infection. Early detection will make it easier to manage the problem. Some of the ways to manage pests and diseases include:
- Handpicking and removing any insects or infected leaves.
- Applying a horticultural oil or insecticidal soap to control pests.
- Applying a fungicide to control fungal diseases.
- Maintaining proper soil drainage and watering to prevent diseases such as root rot.
- Maintaining proper nutrition and light conditions to strengthen the plant's immune system.
- Practicing good hygiene and cleaning gardening tools to prevent the spread of diseases.
By following these management practices, you can keep your Mesembryanthemum speciosum healthy and free from pests and diseases, ensuring that it remains an attractive plant in your garden for years to come.
