Oxalis saronensis F.Bolus, also known as Saron oxalis, is a small shrub-like plant belonging to the Oxalidaceae family. The plant is native to the Western Cape region of South Africa, growing in the winter rainfall areas.
Common Names
Oxalis saronensis F.Bolus is commonly known as Saron oxalis, which refers to the town of Saron, located in the Western Cape region where the plant is found. Other names for the plant include Saron sorrel, pink wood sorrel, and pink oxalis.
Appearance
The Oxalis saronensis F.Bolus plant typically grows up to 50cm in height and has a compact, bushy appearance. The tri-lobed leaves vary in size, ranging from 1-5 cm in length and width, and are a deep green color in the summer and a bronze color in the winter. The blossoms are pink and white with yellow centers, and grow in clusters at the end of long stems.
Uses
The plant is commonly grown for its ornamental value as a decorative plant in gardens and landscapes. In South Africa, it is also used as a medicinal plant for treating various ailments, including stomach aches, diarrhea, and fever. Additionally, some people use the leaves as a food source, as they are rich in vitamin C and have a lemony flavor.
Light Requirements
Oxalis saronensis F.Bolus requires a considerable amount of sunlight exposure to grow and thrive. It is best to place the plant in a spot that receives partial to full sunlight, either indoor near a bright window or outside in a garden where it can receive dappled shade.
Temperature Requirements
The optimal temperature for the growth of Oxalis saronensis F.Bolus is between 18°C to 24°C (64°F to 75°F), which corresponds to the typical room temperature. It is essential to keep the plant away from temperature fluctuations, as it can lead to stunted growth or death.
Soil Requirements
Oxalis saronensis F.Bolus needs well-draining, acidic soil to grow properly. It thrives in a mixture of peat moss, perlite, and sand that offers good drainage and allows for healthy root development. The soil should also be kept moist but not waterlogged, as overwatering can lead to root rot and other problems.
Fertilizer Requirements
Oxalis saronensis F.Bolus requires regular feeding to promote healthy growth and lush foliage. Use a balanced, water-soluble fertilizer once a month during the active growing season. Avoid overfeeding, as it can lead to salt buildup and damage the plant.
Cultivation Methods:
Oxalis saronensis F.Bolus can be grown in both indoor and outdoor environments. It requires well-draining soil and partial shade to full sun for optimal growth. The plant prefers temperatures between 50-80°F and can tolerate a light frost.
It is best to start growing the plant indoors in the early spring, starting with small pots and placing them in a sunny location to allow for adequate growth before transplanting them outside once the weather warms up. Outdoor plants should be planted in early spring in well-draining soil.
Watering Needs:
Oxalis saronensis F.Bolus requires moderate watering, making sure to keep the soil moist but not oversaturated. It is important to avoid allowing the soil to become too dry as this can cause damage to the plant. During the summer months, the plant may require more frequent watering due to increased heat and dryness.
Fertilization:
Fertilization should occur during the growing season, from spring to fall. Use a balanced, slow-release fertilizer every 6-8 weeks to promote healthy growth. It is important not to over-fertilize as it can cause damage to the plant. Be sure to read the instructions on the selected fertilizer and apply accordingly.
Pruning:
Pruning is necessary to promote new growth and maintain the overall health of the plant. It is especially important to remove any dead or damaged foliage as soon as possible. Pruning should be done during the growing season, using clean and sharp tools to avoid the spread of disease. Pinching back the tips of the plant will encourage a more bushy growth pattern. Trim stems back to a node just above where leaves are growing and avoid cutting the stem too far below the node.
Propagation of Oxalis saronensis F.Bolus
Oxalis saronensis F.Bolus can be propagated through different methods, such as seed propagation, division, and rooting of cuttings. Each method has its advantages and disadvantages, and the choice depends on the availability of materials and desired outcomes.
Seed Propagation
Seed propagation is the most common and straightforward method to propagate Oxalis saronensis F.Bolus. Collect the mature seed pods, which turn brown when ripe, and place them in a paper bag to dry before opening and collecting the seeds. The seeds are sown in well-draining soil mix, shallowly covered, and kept moist. Germination occurs within 2 to 3 weeks, and the seedlings need to be transplanted when they grow their second set of true leaves.
Division
Division is the most natural and quickest method to propagate Oxalis saronensis F.Bolus. It is done when the plant is actively growing, preferably in the spring or early fall. To divide, gently dig up the plant, shake off any excess soil, and separate the rosettes or bulbs using a sharp and sterilized knife. Ensure each divided bulb or rosette has its roots attached and replant them in well-draining soil mix.
Rooting of Cuttings
Rooting of cuttings is another method to propagate Oxalis saronensis F.Bolus, but it is not commonly used. The cuttings of about 4-6 cm length are taken from the stem tips in the growing season, dipped in the rooting hormone, and inserted into a well-draining soil mix. It takes up to three weeks for roots to form, and then the plant can be transplanted into a permanent pot or garden bed.
Disease and Pest Management for Oxalis saronensis F.Bolus
Oxalis saronensis F.Bolus is a stunning and delicate plant genus that produces small and colorful flowers. Similar to other plants, the Oxalis saronensis F.Bolus is also vulnerable to pest infestations and various diseases. However, protecting the plant from pests and diseases is essential to keep it healthy and vibrant. Here are some common pests and diseases of the plant and ways to manage them.
Pest Management
Aphids: Small and soft-bodied insects, aphids, or plant lice, infest the stems or the undersides of the leaves. They puncture the cells, leaving wilted and yellowish leaves. To manage these pests, spray the plants with a strong spray of water to remove the aphids from the plant's surface. You can also use horticultural oils or insecticidal soaps to manage aphids.
Spider mites: These tiny insects are barely visible to the naked eye. Another sign of spider mites is to observe a thin web-like layer on the leaves and stems. To control spider mites, remove heavily infested leaves and spray the plant with a strong blast of water. You can also use neem oil, insecticidal soap, or miticide to control the pests.
Caterpillars: These worms feed on the leaves, stems, and flowers and can cause massive damage to the plant. To control caterpillars, remove them by hand. Apply Bacillus thuringiensis (BT) to caterpillar-infested plants to control the pests.
Disease Management
Root rot: Poor drainage and overwatering practices can lead to root rot, where the roots start to decay. To control root rot, ensure that the plant's soil is well-draining and avoid overwatering the plant. Remove infected plants from the soil and discard them.
Powdery Mildew: This disease can occur due to cool and wet weather. Powdery mildew appears as a white, powdery coating on the plant's leaves. To control powdery mildew, improve air circulation, and spray the plant with horticultural oil, potassium bicarbonate, or neem oil.
By following the above-described disease and pest management practices, you can keep your Oxalis saronensis F.Bolus healthy and thriving.
