Origin
Othonna retrofracta F.Bolus, L.Bolus & Glover, also known as the Ruby Necklace plant or String of Rubies, is native to South Africa.
Common Names
The common names for Othonna retrofracta are Ruby Necklace plant and String of Rubies.
Appearance
The Ruby Necklace plant is a succulent that grows as a trailing vine. It has small, oval leaves that are a shiny green color on top and a purple-red color on the bottom. The plant gets its name from the clusters of small, bead-like leaves that grow along the stems, giving the appearance of a string of rubies. As the plant matures, it may produce small yellow flowers at the tips of the stems.
Uses
The Othonna retrofracta is primarily grown as an ornamental houseplant because it is easy to care for and has a unique appearance. It is also a drought-tolerant plant and can survive in dry conditions, making it a great addition to a xeriscape garden. Some people believe that the plant has medicinal properties and use it for healing purposes such as treating stings and bites.
Light Requirements
Othonna retrofracta requires full sun to thrive and grow. It needs at least six hours of direct sunlight every day to photosynthesize and produce energy. Without enough sunlight, the plant may become leggy and weak, affecting its overall health and development. Therefore, it's best to place the plant in a bright, sunny spot, such as a south or west-facing window, balcony, or patio.
Temperature Requirements
The ideal temperature range for Othonna retrofracta is between 60°F to 80°F (15°C to 27°C). It's crucial to avoid exposing the plant to extreme temperature fluctuations, such as sudden drops or rises, as it can lead to stress or damage. In the winter, it's best to keep the plant away from cold drafts and windows, while in the summer, provide adequate ventilation and shading during the hottest hours of the day.
Soil Requirements
Othonna retrofracta grows best in well-draining, sandy soils with a pH level between 6.1 to 7.5. The soil should be rich in organic matter and have good aeration to prevent waterlogging and root rot. It's recommended to use a cactus or succulent mix or create a custom blend of perlite, sand, and peat moss. When potting the plant, ensure that the container has drainage holes to allow excess water to escape and avoid overwatering.
Cultivation
Othonna retrofracta F.Bolus, L.Bolus & Glover, commonly known as Ruby Necklace or String of Rubies, is an attractive succulent plant that can be grown both indoors and outdoors. This plant requires a well-draining potting mix that is rich in organic matter. A suitable soil mix can be made by mixing peat moss, coarse sand or perlite, and a small amount of compost or organic fertilizer.
Othonna retrofracta prefers bright indirect light but can tolerate some direct sunlight. Therefore, it is recommended to place this plant near a window that receives bright natural light. If you are growing this plant indoors, make sure to rotate it every few weeks to provide uniform exposure to light.
Watering Needs
Like most succulents, Othonna retrofracta is drought-tolerant and can survive in low-water conditions. However, it is important to water it thoroughly but sparingly to prevent root rot. It is recommended to allow the soil to dry out completely between watering intervals. A good way to check if the soil is dry is by inserting a finger up to the first knuckle into the soil, and if it feels dry, it's time to water the plant.
During the dormant season, which is typically in winter, watering can be reduced to once every two to three weeks. During the active growing season, which starts in spring and lasts until fall, Othonna retrofracta may require more frequent watering, but make sure not to overwater it.
Fertilization
Fertilization is not crucial for the growth of Othonna retrofracta, but it can promote faster growth and better bloom production. A balanced fertilizer that is low in nitrogen and high in phosphorus can be applied once a month during the growing season. Alternatively, an organic fertilizer that is specifically formulated for succulent plants can also be used according to the manufacturer's instructions.
Pruning
To keep the plant to the desired size and shape, pruning can be done at any time of the year. Pinching off the shoot tips can encourage bushier growth, and removing the withered or yellowing leaves can improve the plant's appearance. Deadheading or removing the spent flowers can also promote the growth of new blooms.
Pruning can be done using a sterilized pair of scissors or gardening shears. Make sure to disinfect the pruning tools before and after use to prevent the spread of diseases.
Propagation for Othonna Retrofracta F.Bolus, L.Bolus & Glover
Othonna Retrofracta F.Bolus, L.Bolus & Glover, commonly known as the Ruby Necklace plant, is a popular succulent plant that is native to South Africa. The plant is easy to grow and maintain, and it is a favorite among gardeners and plant collectors. Propagation of the plant can be done in different ways, which include:
Propagation by Seeds
The Ruby Necklace plant can be propagated by seeds. The first step in propagating the plant by seeds is collecting the seeds from a mature plant. The seeds should be allowed to dry for a few days before sowing. The seeds can be sown in a well-draining soil mix and covered with a thin layer of soil. The soil should be kept moist and warm until the seeds germinate, which should take about 2-3 weeks. Once the seedlings are established, they can be transplanted into individual pots.
Propagation by Stem Cuttings
The Ruby Necklace plant can also be propagated by stem cuttings. The cuttings should be taken from a healthy plant in the spring or early summer. The cuttings should be about 3-4 inches long and should be allowed to dry for a few days before planting. The cuttings should be planted in a well-draining soil mix and kept moist until roots form, which should take about 2-3 weeks. Once the roots are established, the new plant can be transplanted into individual pots.
Propagation by Division
The Ruby Necklace plant can also be propagated by division. Dividing the plant involves separating the plant into two or more sections, each of which grows into a new plant. This method of propagation is best done in the spring when the plant is actively growing. Carefully dig up the plant, and separate the offsets from the mother plant. Each offset should have roots and at least one leaf. Plant the offsets in individual pots with well-draining soil mix and water them. Keep them in a bright, warm, and humid environment until they are established.
Propagation of the Ruby Necklace plant can be done using different methods, and the choice depends on the grower's preference and availability of resources. Regardless of the method used, the plant requires proper care and maintenance to thrive.
Disease Management
The Othonna retrofracta is a relatively healthy plant. However, it can be affected by some fungal diseases including powdery mildew, leaf spot, and root rot. To manage these diseases, you need to ensure that the plant is properly watered and the soil is well-drained. Also, avoid overcrowding the plant and promoting air circulation by proper spacing. Fungicides can also be used, but always read the label directions carefully before applying any chemicals.
Pest Management
Othonna retrofracta is attacked by a few pests, including spider mites, aphids, mealybugs, and thrips. These pests suck the sap and weaken the plant, leading to stunted growth and death in severe infestations. To manage these pests, you can use insecticides and acaricides, but ensure that they are safe for use on the plant. You can also use natural predators like ladybugs and lacewings to control the pests. Proper sanitation practices such as removing infested plant parts, cleaning tools, and avoiding the use of infected soil are also effective ways to prevent pest infestations.
