Light Requirements
Othonna coriifolia Sond. typically requires full sun to partial shade for optimal growth. This plant requires a minimum of 6 hours of direct sunlight per day to thrive. If grown indoors, it is recommended to place the plant near a south-facing window or provide artificial light for at least 10 hours a day.

Temperatures below 50°F (10°C) can cause damage to the plant. If grown indoors, it is recommended to maintain a consistent temperature and avoid placing the plant near drafty windows.
Soil Requirements
The soil for Othonna coriifolia Sond. should be well-draining and not too dense. A mixture of potting soil and sand or perlite is recommended to ensure proper drainage. The pH of the soil should be slightly acidic to neutral, between 6.0-7.5. Fertilization should be done sparingly, as this plant is adapted to low-nutrient environments. It is recommended to fertilize every 4 weeks with a balanced fertilizer diluted to half strength.
Cultivation
Othonna coriifolia Sond. is a hardy plant that grows well in various soil types, ranging from sandy soil to loamy soil. It thrives well in areas with well-drained soil, and the pH level of the soil should be slightly acidic.
The plant prefers areas with adequate sunlight exposure and can tolerate direct sunlight, making it ideal for outdoor cultivation. It is essential to plant the seeds or seedlings in areas protected from strong winds and extreme temperatures.
Propagation is possible through seeds or cuttings. If using cuttings, it is vital to dip the cut end in rooting hormone powder before planting it in soil mixtures made up of peat moss, perlite and sand.
Watering Needs
Othonna coriifolia Sond. requires moderate watering. Overwatering the plant can lead to root rot, so it's critical to water only when the soil is dry. A good tip is to check the soil's moisture level in the top 2-3 inches before watering.
During the winter months, it is essential to reduce watering as the plant tends to go dormant during this period, and overwatering can cause root rot.
Fertilization
When it comes to fertilization, Othonna coriifolia Sond. does not require too much, and excessive fertilizers can harm the plant. A balanced fertilizer such as a 10-10-10 works well, and it is ideal to apply during early spring and mid-summer.
It is essential to follow the manufacturer's instructions and avoid over-fertilization, as it can cause weak growth and damage to the plant.
Pruning
Othonna coriifolia Sond. requires moderate pruning to keep it looking tidy and compact. Deadheading, or removal of spent blooms, can promote the growth of new flowers.
Softwood pruning is advisable during the summer months. A good rule of thumb is to prune to remove any dead, damaged, or infected areas. It is best to prune early in the morning or late in the evening to prevent stress on the plant due to high temperatures.
Propagation methods of Othonna coriifolia Sond.
Othonna coriifolia Sond. is a perennial groundcover plant that is native to South Africa. It is also known as the "Ruby Necklace" due to its striking appearance. Propagation of this plant is relatively easy and can be done through several methods, including seed propagation, stem cuttings, and division.
Seed propagation
Seeds can be collected from the plant after the flowers have bloomed and the ovules have matured. The seeds are then cleaned, and planted in a well-draining soil mix. The soil should be kept moist until the seedlings emerge, which can take up to two weeks. After that, the seedlings should be gradually acclimated to direct sunlight and the outdoors.
Stem cuttings
Stem cuttings can also be used to propagate Othonna coriifolia Sond. Take a stem cutting from the plant about 4 to 6 inches long, making sure it has at least one node. Remove the bottom leaves and dip the cutting into rooting hormone. Then, plant it in a well-draining soil mix and keep it moist. It should develop roots within a few weeks and can be transplanted into a larger pot or outdoors.
Division
Othonna coriifolia Sond. can also be propagated through division, which involves separating the plant into smaller sections that each contain a portion of the roots. This method should be carried out in the spring, and the sectioned plants should be replanted in well-draining soil mix and kept moist. They should be acclimated to direct sunlight and the outdoors gradually.
Regardless of the propagation method used, Othonna coriifolia Sond. grows best in well-draining soil in full to partial sunlight. It is also important to keep the soil moist but not waterlogged, as this can lead to root rot. With proper care, this plant can bring a pop of color to any garden or indoor space.
