Origin
Othonna subumbellata, also known as the "pickle plant" or "ruby necklace," is a species of flowering plant in the Asteraceae family. It is native to South Africa and Namibia, where it grows in rocky areas and on slopes.
Common names
The common names of Othonna subumbellata are pickle plant and ruby necklace. The former name comes from the plant's leaves, which resemble small pickles, while the latter name comes from the bright red color of the stems and leaves.
Uses
Othonna subumbellata is primarily grown as an ornamental plant in gardens and as a houseplant. Its unique appearance, with its fleshy, cylindrical leaves and red stems, makes it a popular choice for those looking for a low-maintenance, visually striking plant. It is also suitable for planting in hanging baskets or as a ground cover. The leaves of this plant are edible but are not commonly consumed.
General appearance
Othonna subumbellata is a succulent plant with cylindrical, fleshy leaves that range in length from 1-3 inches. The leaves are a bright green color and have a waxy appearance. The stems of the plant are also cylindrical, reddish-brown in color, and grow in a trailing manner. The plant produces small, yellow, daisy-like flowers that bloom in the spring and summer.
Light Requirements
Othonna subumbellata DC. prefers full sunlight to partial shade. It can grow well even in direct sun exposure, although it may require more water to keep the soil moist.
Temperature Requirements
The plant grows best in warm temperatures between 60 and 80 degrees Fahrenheit (15-27 degrees Celsius). It can tolerate a minimum temperature of 50 degrees Fahrenheit (10 degrees Celsius) and a maximum temperature of 95 degrees Fahrenheit (35 degrees Celsius).
Soil Requirements
Othonna subumbellata DC. prefers well-draining sandy or loamy soil with a slightly acidic to neutral pH level (6.0-7.0). The soil should be nutrient-rich and should not be compacted as it can restrict root growth and airflow. Addition of organic matter, such as compost or manure, can improve soil fertility and texture.
Cultivation methods
Othonna subumbellata DC. is a drought-tolerant plant that requires well-draining soil and a sunny location to thrive. It is best grown in USDA hardiness zones 9-11. The plant can be propagated by seeds or stem cuttings, with stem cuttings being the preferred method. When planting, make sure to give the plant enough space as it can spread up to 3 feet wide. The soil should be well-draining and slightly acidic to neutral. If the soil is not naturally well-draining, it can be amended with organic matter to improve drainage.Watering needs
Othonna subumbellata DC. is a drought-tolerant plant that can survive on low water levels. However, it is important to water the plant deeply every 7-10 days during the growing season. This will help the plant establish a deep root system and encourage healthy growth. Avoid overwatering the plant as it can lead to root rot and other diseases. The best way to determine if the plant needs water is by checking the soil moisture level. Stick your finger about 2 inches into the soil, and if it feels dry, it's time to water.Fertilization
Othonna subumbellata DC. does not require frequent fertilization. However, it can benefit from a slow-release fertilizer applied in the spring. The fertilizer should be low in nitrogen and high in phosphorus and potassium. Over-fertilization can lead to excessive foliage growth and reduced blooming. It is important to follow the manufacturer's instructions when applying fertilizer.Pruning
Othonna subumbellata DC. does not require frequent pruning. However, pruning can be beneficial to shape the plant and to remove any dead or diseased branches. Pruning should be done in the early spring when new growth begins to emerge. Avoid pruning too aggressively as it can reduce blooming. It is important to use sharp, clean tools when pruning to prevent damage to the plant.Propagation of Othonna subumbellata DC.
Othonna subumbellata DC. is a plant that can be propagated through various methods. Here are some of the common propagation methods:
Propagation through Cuttings
The most common method of propagating Othonna subumbellata DC. is through cuttings. Choose healthy stems, about 4-6 inches in length, and cut them just below a node. Remove the leaves from the bottom of the stem and dip it in a rooting hormone before planting it in a container filled with potting soil. Water it regularly, and within a few weeks, new roots will form, and new growth will appear.
Propagation through Division
Othonna subumbellata DC. can also be propagated through division, which involves dividing the plant's roots into sections and replanting them in new soil. This method is suitable for mature plants that have multiple stems. Carefully remove the plant from its container, gently separate the stem clusters, and plant them in a new container filled with potting mix. Be sure to water the new plants well, and they will take root and produce new growth.
Propagation through Seeds
Propagation through seeds is less common for Othonna subumbellata DC. This method involves starting the seeds indoors, planting them in a tray filled with potting mix. After the seeds germinate, transplant them into individual containers filled with potting soil and water regularly. However, propagating through seeds requires more patience and care than the other methods.
Overall, Othonna subumbellata DC. is an easy-to-grow plant with various propagation methods. Whether you choose to propagate through cuttings, division, or seeds, with proper care, your new plant will thrive and produce beautiful foliage and flowers.
Disease and Pest Management for Othonna subumbellata DC.
Othonna subumbellata DC., commonly known as the “little pickles” plant, is a South African succulent shrub that is relatively easy to grow. However, just like any other plant, it is susceptible to diseases and pests that can threaten its health and appearance. Proper disease and pest management practices can help ensure that the plant remains healthy and vibrant.
Common Diseases
One of the most common diseases that affect Othonna subumbellata is root rot. This disease is caused by overwatering the plant and can lead to the plant’s death. The infected plant may show wilted leaves and discoloration, which can eventually spread to the stem and kill the plant. Soil-borne fungal diseases like fusarium and pythium can cause rotting roots and yellowing of leaves.
Pest Management
In addition to diseases, pests can also attack Othonna subumbellata. Common pests that infest this plant include mealybugs, spider mites, scale insects, and aphids. These pests can cause damage to the plant by sucking out its sap and reducing its vigor. If left unchecked, they can cause severe damage to the plant and even cause its death.
Disease Management
To manage root rot in Othonna subumbellata, it is essential to avoid overwatering and amending the soil with a well-draining soil mix. Using a fungicidal spray can also help control the spread of fungal diseases. It’s also a good idea to avoid watering that could create moisture on leaves so they don't become infected with fungal diseases. Using a balance of minerals such as nitrogen, phosphorus, potassium, and calcium can also help the plant strengthen their root system and help avoid disease.
Pest Control Methods
To manage pests like mealybugs and scale insects, you can wipe them off with a soft damp cloth or use an insecticidal spray. Applying neem oil or rubbing alcohol on the infested plant parts can also be effective. For spider mites, spraying the plant with insecticidal soap or horticultural oil can be a good approach. If the plant is heavily infested, the use of a miticide is advisable. Regular inspection of plants, especially those from outside sources, to avoid the introduction of diseases and pests can also be a good prevention.
With proper disease and pest management practices, Othonna subumbellata DC. can provide a beautiful addition to any indoor or outdoor garden.
