General Appearance of Othonna amplexicaulis Thunb.
The 'Ruby Necklace' plant features small, round leaves that are about 1/4 inch in diameter. The leaves are green on top, while the undersides are a deep ruby red color. The plant's bright yellow, daisy-like flowers grow on stalks that emerge from the center of the plant. The flowers bloom in summer and fall and are about 1 inch in diameter. The stems of the plant are thin, fleshy, and can grow up to several feet long, making it an ideal groundcover.
Growth Conditions of Othonna amplexicaulis Thunb.
Othonna amplexicaulis Thunb., also known as the Ruby Necklace, is a succulent plant native to southern Africa. It is a low-growing, trailing plant that typically reaches 6 to 12 inches in height and spreads up to 3 feet wide.
Light Requirements
This plant prefers to grow in full sun but can also tolerate partial shade. In areas with intense sunlight, it is best to provide some afternoon shade to prevent scorching of the foliage. However, insufficient sunlight may cause the plant to stretch and become leggy.
Temperature Requirements
The optimal temperature range for Othonna amplexicaulis Thunb. is between 50 to 70 degrees Fahrenheit. It cannot tolerate frost and prefers a warm, dry climate. In areas with colder temperatures, it is best to grow the plant in containers and move them indoors during the winter months.
Soil Requirements
This plant grows well in well-draining soil with a pH range of 6.0 to 7.0. It can tolerate poor soil conditions, but it is best to amend the soil with compost or sand to improve drainage. Avoid overwatering, as this can cause root rot and damage to the plant.
Water Requirements
Othonna amplexicaulis Thunb. is drought-tolerant and can survive long periods without water. It is best to water this plant infrequently but deeply, allowing the soil to dry out between watering. However, be cautious of overwatering, as this can cause root rot and damage to the plant. During the winter months, it is best to reduce watering to prevent the plant from becoming waterlogged.
Cultivation methods for Othonna amplexicaulis Thunb.
Othonna amplexicaulis Thunb. is a fast-growing perennial. It is best grown in well-draining soil, with a pH level of 6.1 to 7.8. The plant thrives in full sunlight, but it can tolerate partial shade. Sow the seeds directly into the pot or bed, or start the plant from a stem cutting. Cover the seeds with a thin layer of soil and keep them moist until germination.
Watering needs for Othonna amplexicaulis Thunb.
It is crucial to keep the soil moist but not waterlogged, as excessive moisture may cause the plant's roots to rot. Water the plant once or twice weekly, depending on the weather conditions. During the hot and dry season, increase the watering frequency. Reduce watering during the winter months.
Fertilization of Othonna amplexicaulis Thunb.
Although Othonna amplexicaulis Thunb. is a low-maintenance plant, it can benefit from regular fertilization. Fertilize the plant every four to six weeks using a balanced slow-release fertilizer, or a liquid fertilizer diluted at half strength. Avoid over-fertilizing the plant, as it can lead to salt buildup and root burn.
Pruning of Othonna amplexicaulis Thunb.
Pruning the plant is not necessary, but it can help keep the plant in shape and control its size. Trim back any overgrown or dead foliage as needed. Pinch the tips of the plant's stems to encourage branching and promote bushier growth.
Propagation of Othonna amplexicaulis Thunb.
Othonna amplexicaulis Thunb., also known as the ruby necklace plant or little pickles, is a succulent perennial plant that belongs to the Asteraceae family. This plant is popular for its unique appearance, as it features long, trailing stems covered in small, bean-shaped leaves that are bright green in color and look like little pickles. Propagation of this plant can be done through various methods, such as stem cuttings, division, and seed planting.
Stem Cuttings
Propagation through stem cuttings is a popular and simple method for Othonna amplexicaulis Thunb. This method involves taking a stem cutting from a parent plant and planting it in a suitable potting mix. The cutting should be taken from the healthy, mature stem of the plant during its active growing season. The cutting should be around 3-4 inches long and should have a few leaves on it.
After taking the cutting, remove the leaves from the bottom of the stem, leaving only a few leaves on the top. Dip the end of the cutting in rooting hormone powder and plant it in a potting mix that is well-draining and rich in organic matter. Water the cutting sparingly and keep it in a bright, warm, and humid location until it roots and starts to grow new leaves.
Division
Propagation through division is another method for Othonna amplexicaulis Thunb. This method involves separating the parent plant into smaller individual plants to replant. This method should be done during the active growing season and when the parent plant has grown larger and has several shoots or stems.
To propagate through division, carefully remove the parent plant from its pot or soil, and gently separate the stems or shoots from the root ball, making sure each division has its own set of roots. Replant the divisions in their individual pots or in a well-draining soil mix. Water them adequately and keep them in bright, indirect light until they establish and start to grow.
Seed Planting
Propagation through seed planting is another method for Othonna amplexicaulis Thunb. This method involves collecting the mature seeds from the parent plant and planting them into a suitable soil mix. This method takes longer compared to the other methods, as the seeds need to germinate and grow into a mature plant.
To propagate through seed planting, collect the mature seeds from the parent plant during the flowering season. The seeds should be sown into a well-draining soil mix that is moist. Cover the pots with a plastic bag or a sheet of plastic wrap to create humidity, and keep them in a warm location, with bright, indirect light.
Germination should occur in about two weeks, and once the seedlings are large enough, they can be transplanted into their individual pots or a larger container. Water them adequately and keep them in a bright, sunny location.
Disease Management:
Othonna amplexicaulis is susceptible to fungal infections such as powdery mildew and leaf spot. To manage powdery mildew, it is essential to maintain proper air circulation around the plant by spacing them appropriately. Also, avoid watering the foliage, remove diseased leaves, and apply a fungicide as recommended. Leaf spot can be managed by watering at the base of the plant and not overhead, avoiding crowding, and removing the infected leaves. A fungicide application would also be helpful.
Pest Management:
The most common pests that affect Othonna amplexicaulis are aphids and spider mites. Aphids can be managed using insecticidal soap or neem oil. For spider mites, applying a forceful spray of water to the undersides of leaves can lessen their population. Also, introducing natural predators such as ladybugs and lacewings is useful in controlling aphids and spider mites.
