In South Africa, Mesembryanthemum collinum Sond. is often used in traditional medicine to treat various ailments including coughs, colds, and influenza. It is also used as a poultice for wounds, bites, and stings.
Additionally, Mesembryanthemum collinum Sond. is commonly grown as an ornamental plant due to its attractive flowers and ability to adapt to dry conditions. It is also suitable for use in rock gardens and succulent collections.
Light Requirements
Mesembryanthemum collinum Sond. thrives in full sunlight and requires at least six hours of direct sunlight per day. Failure to provide sufficient light may lead to stunted growth or even death of the plant.
Temperature Requirements
For optimal growth, the plant requires warm temperatures ranging from 18-25°C. The plant is not frost-resistant, and exposure to colder temperatures could cause damage or death of the plant. If growing Mesembryanthemum collinum Sond. in areas with colder climates, it is best to transfer them indoors or to a greenhouse during winter.
Soil Requirements
The plant grows best in well-draining soil with a pH level ranging from slightly acidic to neutral. Mesembryanthemum collinum Sond. can tolerate poor soils, but soil that is too acidic or nutrient-deficient could inhibit growth and flowering. Adding organic matter, such as compost or manure, could enhance soil fertility and improve soil structure for better growth of the plant.
Cultivation methods
Mesembryanthemum collinum Sond., commonly known as dew plant, is a popular plant known for its bright, daisy-like flowers, and fleshy leaves. It is native to South Africa and is recognized for its easy-to-grow nature.
The plant grows well in warm and dry weather conditions and does not require much attention. Mesembryanthemum collinum Sond. thrives well in sandy and well-drained soils that are slightly acidic. The optimum temperature required for the plant to grow is between 25-30°C.
In terms of light, the plant prefers full sunlight. Therefore, it is advisable to keep it in a location where it can get at least 6-8 hours of sunlight per day. Additionally, the plant does well when it is sheltered from strong winds as the stems are prone to breaking.
Watering needs
Mesembryanthemum collinum Sond. requires minimal watering, primarily when it is grown in pots or containers. The plant requires watering when the top layer of soil has dried out. Overwatering can lead to root rot, limiting growth and affecting the plant's health.
It is advisable to apply water to the surface of the potting media and avoid getting water on the leaves and stems of the plant. During the winter months, watering should be reduced, and the roots kept dry to prevent rotting.
Fertilization
The dew plant does not require frequent fertilizer application since it is adaptable to poor soils. However, a monthly application of a general-purpose fertilizer can help improve growth and flowering.
It is important to avoid applying too much fertilizer as it can lead to salt buildup in the soil, making it unsuitable for the plant's growth. Therefore, use a balanced fertilizer and follow the instructions on the package to avoid overfeeding the plant.
Pruning
Mesembryanthemum collinum Sond. does not require much pruning. However, regular removal of dead or yellowing leaves and flowers can help improve the aesthetic appeal of the plant.
It is advisable to use a sharp and sterilized pair of scissors when pruning the plant to prevent any possible infection. Additionally, pruning can help prevent the plant's legginess and promote bushier growth.
Propagation of Mesembryanthemum collinum Sond.
Mesembryanthemum collinum Sond. is commonly known as Collinevy. The plant is native to southern Africa and grows in sandy or rocky soils. Collinevy is a low-growing, perennial succulent plant that produces striking pink flowers from September to November. The easiest way to propagate M. collinum is through stem cuttings.
Stem Cuttings
The best time to take stem cuttings from M. collinum is during the spring or early summer when the plant is actively growing. Select a healthy stem with no flower buds and cut it using a clean, sharp pair of scissors or knife. The cutting should be around 5-7cm long.
Remove the lower leaves from the cutting and leave 2-3 pairs of leaves at the top. Allow the cuttings to dry out for a few days until a callus forms at the base. Make sure the cuttings are not exposed to direct sunlight.
Fill a pot with well-draining soil mix and make a hole using a pencil or your finger. Place the cutting in the hole and firm the soil around it. Water the cutting sparingly to avoid rotting.
Provide the cutting with bright indirect light and maintain a temperature between 18-24°C. The cutting should root within 2-4 weeks, after which small leaves will appear.
After a few weeks, when the cutting has established roots, transplants it into a larger pot or directly into the garden soil.
