Overview
Mesembryanthemum obtusum Haw. is a succulent plant that is native to South Africa. It belongs to the family Aizoaceae and is known for its vibrant flowers and thick, fleshy leaves. The plant is commonly referred to as the ice plant or bokbaai vygie in South Africa.
Description
The ice plant typically grows to be around 4-6 inches in height and spreads outwards up to 12 inches in diameter. The plant's leaves are generally small and lanceshaped, with a greenish-grey color and a smooth, papery texture. Its flowers grow on short stems, with thin petals that can range from white to pink or yellow in color. The flowers only open up when exposed to sunlight and typically bloom in the summer months.
Uses
Mesembryanthemum obtusum is commonly used as a decorative plant for gardens and indoor spaces. Its unique appearance and vibrant flowers make it a popular choice for adding color and texture to any space. In addition, the plant is also used for medicinal purposes. It has been found to have anti-inflammatory properties and has been used to treat stomach ulcers and skin irritations.
The plant's leaves are also edible and have a slightly salty taste. In South Africa, the leaves are often pickled and used as a condiment or added to salads to add a crunchy texture. The plant's ability to thrive in arid conditions has also led to its use in erosion control and land reclamation projects.
Cultivation
The ice plant is a low-maintenance plant and is generally easy to grow. It prefers well-drained soil and a sunny location, but can also tolerate partial shade. The plant does not require frequent watering and can survive long periods of drought. In fact, overwatering can be detrimental to the plant and can lead to root rot. Propagation can be done through stem cuttings or by sowing seeds in the spring. The ice plant is also known to attract butterflies and bees, making it a great addition to any garden or outdoor space.
Light Requirements:
Mesembryanthemum obtusum Haw. is a sun-loving plant that requires full sun to grow properly. The plant should receive at least 6 to 8 hours of direct sunlight every day to thrive. Lack of proper sunlight can result in spindly growth and poor flower development, making it essential to place the plant in a location with adequate sunlight exposure.
Temperature Requirements:
Mesembryanthemum obtusum Haw. grows well in a wide range of temperatures. Ideally, the plant requires a temperature range of 60°F to 80°F (15°C to 27°C) throughout the year. The plant can tolerate higher temperatures for a short period, but it is better to keep the temperature around 70°F (21°C) during the day and 50°F (10°C) at night.
Soil Requirements:
Mesembryanthemum obtusum Haw. plants prefer well-draining and nutrient-rich soil, which should be slightly acidic to neutral. Sandy or loamy soil is the best suited for the plant’s growth, and it can handle various types of soil, including alkaline, acidic, and even poor soil. The soil should also allow excess water to drain away quickly, as prolonged soil moisture can lead to root rot and other diseases.
Cultivation Methods for Mesembryanthemum obtusum Haw.
For cultivation, choose a location with well-drained soil and full sunlight exposure. The plant grows well in warm temperatures, preferably 68°F to 86°F (20°C to 30°C).
You can propagate the plant by seed or cuttings. Sow the seeds in a seed tray or directly in the prepared garden bed when the temperature is above 64°F (18°C). The germination time is typically two weeks. For cuttings, select the healthy branches and cut them at a 45-degree angle before planting.
Keep the plants about 8 to 12 inches apart to provide ample space for growth. The plant can grow up to 6 inches in height and about the same width.
Watering Needs for Mesembryanthemum obtusum Haw.
The plant requires moderate watering. Water the plant when the top layer of soil feels dry to the touch. However, do not overwater, as this may cause root rot. During the winter season, water less frequently.
It is advisable to water the plant in the early hours of the day to reduce evaporation and control the moisture levels.
Fertilization for Mesembryanthemum obtusum Haw.
The plant requires minimal fertilization. You can use a well-balanced fertilizer, such as 10-10-10, once a month during the growing season. However, do not over-fertilize, as this may cause the plant to produce few flowers.
Alternatively, you can use compost or organic matter to fertilize the plant. Apply the compost around the base of the plant and gently mix it into the soil.
Pruning Mesembryanthemum obtusum Haw.
The plant does not require regular pruning, but it's advisable to deadhead spent flowers regularly. Once the plant starts to wilt or wither, trim the dead foliage to encourage growth.
During the winter season, cut the plant back to about half its size to prepare it for spring growth. This will also maintain the shape of the plant.

- Plant the seeds in well-drained soil and cover them lightly with soil.
- Water the soil and keep it moist until the seeds germinate, which usually takes one to two weeks.
- Once the seedlings have grown a few sets of true leaves, you can transplant them to individual pots or a garden bed.
Propagation of Mesembryanthemum obtusum Haw. is relatively easy, and the plant grows quickly, making it an excellent choice for beginners or anyone looking to expand their collection of succulent plants.
Disease and Pest Management for Mesembryanthemum Obtusum Haw.
Mesembryanthemum obtusum Haw., commonly known as "ice plant," is a popular succulent plant that is known for its attractive, colorful daisy-like flowers and its ability to grow in various soil types. However, just like any other plant, it is susceptible to attacks from pests and diseases. Proper disease and pest management is crucial in maintaining the health and appearance of this plant.
Common Diseases
Crown Rot: This is a fungal disease that causes the plant to wilt and die. It is caused by overwatering and poor drainage. To manage this disease, ensure the soil is well-draining and use appropriate watering techniques.
Leaf Spot: This disease is caused by fungi and bacteria that cause spots on the leaves, leading to leaf drop and weakening of the plant. To manage this disease, ensure the plant is not overcrowded, and that there is proper air circulation around the plant. Remove affected leaves and ensure the soil is not too wet.
Root Rot: This disease is also caused by overwatering and poor drainage. It causes the roots to rot, leading to the decline and eventual death of the plant. To manage this disease, ensure the soil is well-draining and avoid overwatering the plant.
Common Pests
Scales: These insects appear as small bumps on the plant's stem and leaves and can cause yellowing and wilting of leaves. To manage scales, prune affected parts of the plant and use insecticidal soap.
Mealybugs: These insects appear as white, cottony spots on the plant's leaves and stem. They sap the plant's sap and can cause stunted growth. To manage mealybugs, wipe them off with a cotton swab soaked in alcohol or use insecticidal soap.
Aphids: These insects cluster on the plant's stems and leaves and can cause yellowing and wilting of leaves. To manage aphids, prune affected parts of the plant and use insecticidal soap.
Spider Mites: These insects cause the plant's leaves to appear stippled or have a bronzed appearance. To manage spider mites, hose them off with a stream of water or use insecticidal soap.
By ensuring proper watering and drainage techniques and promptly managing any pest or disease outbreaks, plant owners can maintain healthy, thriving Mesembryanthemum obtusum Haw plants.
