Overview of Mesembryanthemum angulatum Thunb.
Mesembryanthemum angulatum Thunb., also known as Angular Sea Fig, is a succulent plant that is characterized by its fleshy and angular leaves. This plant belongs to the family Aizoaceae and is native to South Africa, specifically in the Cape Province.
Common Names
Aside from Angular Sea Fig, Mesembryanthemum angulatum Thunb. is also known by a variety of names, including:
- Ice Plant
- High Noon
- Fig Marigold
- Bushman’s Candle
General Appearance
The Angular Sea Fig can grow up to 6 inches tall, and it has long, thin, and angular leaves that range from green to purple. The leaves can become red under exposure to sunlight. In the summer months, the plant produces bright yellow flowers that only open on sunny days. The flowers bloom from July to September. Angular Sea Fig is a fast-growing plant and can spread up to a foot per year.
Uses
Mesembryanthemum angulatum Thunb. is commonly used as an ornamental plant because of its unique appearance. It is suitable for growing in rock gardens, containers, and as a ground cover. The plant is drought-tolerant and can withstand extreme temperatures.
Angular Sea Fig is also used in traditional medicine for its antibacterial and anti-inflammatory properties. In South Africa, the plant’s sap is used for treating ear infections and boils. The sap is sometimes made into a candle for lighting purposes, which is how it got its other common name, Bushman’s Candle.
Light requirements
Mesembryanthemum angulatum Thunb. is a sun-loving plant that requires full sunlight for proper growth and development. It can tolerate partial shade, but it will not thrive in low light conditions. Therefore, it is best to grow the plant in an area where it will receive at least six hours of direct sunlight each day.
Temperature requirements
The plant prefers warm temperatures and can tolerate high heat up to 95°F. However, it cannot withstand frost or freezing conditions and requires a minimum temperature of 50°F to survive. Therefore, it is best to plant Mesembryanthemum angulatum Thunb. in areas where the minimum temperature stays above 50°F throughout the year.
Soil requirements
Mesembryanthemum angulatum Thunb. prefers well-drained soil that is rich in organic matter. The plant can tolerate various soil types, including sandy, loamy, and rocky soils with a pH range of 6.0 to 7.5. However, it cannot thrive in waterlogged or poorly drained soil. It is best to add compost or organic matter to the soil to improve its quality and drainage before planting this species.
Cultivation Methods
Mesembryanthemum angulatum Thunb. is a drought-resistant plant that thrives in well-drained soils and requires full sunlight. It is best grown in sandy soils with a pH range of 6.0-7.0. The ideal time to plant the seeds is during the early spring, and they should be spaced out about 20-30cm apart. Alternatively, this plant can also be propagated through cuttings.
Watering Needs
Mesembryanthemum angulatum Thunb. is highly tolerant of drought conditions and as such, only requires occasional watering. Overwatering can lead to root rot and other diseases that affect their growth and overall health. It is advisable to use a well-draining soil mix that allows for excess water to drain out properly.
Fertilization
This plant does not require much fertilizer, but if the soil is poor, a balanced fertilizer can be used. It is best to fertilize during the growing season, usually from early spring to mid-summer. Overfertilizing can lead to excessive foliage growth at the expense of flowers.
Pruning
Mesembryanthemum angulatum Thunb. does not require any pruning, but if it becomes overgrown, it can be trimmed back to keep the plant tidy. Deadheading can also be done to encourage more flower buds to form. Regularly trimming the plant will help improve its overall health and appearance.
Propagation of Mesembryanthemum angulatum Thunb.
Mesembryanthemum angulatum Thunb. is propagated through various methods, including:
1. Seed propagation
Seeds are the most common method of propagating Mesembryanthemum angulatum Thunb. The seeds are small and should be sown in well-draining soil. The soil should be moist, but not too wet as wet soil can lead to fungal growth.
The seeds can be planted in a seed tray or directly in the ground. When planting in a seed tray, plant the seeds approximately 1cm deep. Once the seedlings have grown to about 10cm in height, they can be transplanted.
2. Stem cutting propagation
Propagation through stem cuttings can be done in the summer months. The ideal stem cuttings are approximately 5cm long and taken from healthy plants. The cuttings should be allowed to dry for a few days before planting.
The cuttings can be planted in well-draining soil, with the bottom 1cm buried in the soil. The soil should be kept moist, but not too wet. Within a few weeks, new growth should appear.
3. Division propagation
Division propagation is another method of propagating Mesembryanthemum angulatum Thunb. It involves dividing the plant's root ball into multiple smaller plants. This method is best done in the spring.
To divide the plant, carefully remove it from the soil and gently separate the root ball into two or more sections. Replant the sections in well-draining soil and water them thoroughly. Be sure to keep them out of direct sunlight until new growth has appeared.
Disease and Pest Management for Mesembryanthemum angulatum Thunb.
Mesembryanthemum angulatum Thunb., commonly known as angular leaf ice plant, is a low-growing plant with vibrant pink flowers that bloom from late spring to early summer. To maintain the plant's health and beauty, it's important to keep an eye out for common diseases and pests that may affect it. Here are some of the most common issues and ways to manage them:
Diseases
Angular leaf ice plants are generally resistant to many diseases, but there are a few that can affect them:
Root Rot
Root rot can occur if the soil is too wet or if there is poor drainage. If you notice the plant looking wilted or the leaves turning yellow, you may have root rot. To manage this, remove any affected plants and improve the soil's drainage by adding coarse sand or perlite.
Leaf Spots
Leaf spots are caused by fungal infections and can occur in areas with high humidity. If you notice dark, water-soaked spots on the leaves of your plant, you may have leaf spots. To manage this, remove any affected leaves and improve air circulation around the plant by spacing them out and pruning them regularly.
Pests
Angular leaf ice plants are also susceptible to a few pests:
Aphids
Aphids are small, pear-shaped insects that can be found on the undersides of leaves. They suck the sap from the plant, which can reduce its overall health. If you notice a sticky residue on the leaves or curled and distorted leaves, you may have an aphid infestation. To manage this, you can spray the plant with a solution of water and dish soap or use an insecticidal soap.
Mealybugs
Mealybugs are small, white insects that look like bits of cotton. Like aphids, they suck sap from the plant. If you notice a white, powdery substance on the plant or stunted growth, you may have a mealybug infestation. To manage this, you can remove them manually with a cotton swab dipped in alcohol or use an insecticidal soap.
By taking proactive measures and monitoring your plants for any signs of disease or pest infestations, you can help keep them healthy and thriving.
