Light Requirements
Oxalis polyphylla Jacq. var. alba T.M.Salter grows best in partial to full shade. It can tolerate some direct sunlight, but too much can scorch its leaves. If grown indoors, place the plant near a window that receives filtered light.
Temperature Requirements
Temperature requirements vary depending on the time of year. During the growing season, the ideal temperature range is between 60-75°F (15-24°C). In the winter, the plant can tolerate temperatures as low as 45°F (7°C) but will not grow actively. Protect the plant from extreme temperature fluctuations, as sudden changes in temperature can cause stress and damage.
Soil Requirements
Oxalis polyphylla Jacq. var. alba T.M.Salter needs well-draining soil that is rich in organic matter. The soil should be moist but not waterlogged. A soil pH between 5.5-7.5 is ideal for this plant. Use a good quality potting mix or make your own by combining equal parts of peat moss, perlite, and vermiculite.
Cultivation Methods
Oxalis polyphylla Jacq. var. alba T.M.Salter, also known as the white-flowered wood sorrel, is a beautiful and easy-to-care-for plant that can be grown both indoors and outdoors. If you plan on growing this plant indoors, choose a well-lit spot away from direct sunlight. The plant grows best in partial shade and moist environments. If planting outdoors, choose a location with well-draining soil and partial shade.
Watering Needs
A consistent watering schedule is crucial for keeping Oxalis polyphylla Jacq. var. alba T.M.Salter healthy and thriving. The plant prefers moist soil, but it is essential not to overwater it. The best way to water the plant is to wait until the top inch of the soil feels dry to the touch before watering it again. During the summertime, the plant may require more frequent watering than during the winter months.
Fertilization
Oxalis polyphylla Jacq. var. alba T.M.Salter does not require frequent fertilization. Fertilize the plant in the growing season, from spring to fall, using a balanced fertilizer at half strength. Over-fertilizing the plant can lead to root burn, so always read the fertilizer instructions before using it on your plant.
Pruning
Pruning can help the plant maintain a robust and healthy shape. Prune back any yellow or dead leaves as soon as possible, as it helps maintain good airflow and prevents fungal growth. Also, Oxalis polyphylla Jacq. var. alba T.M.Salter can become leggy over time, and pruning can help control its growth. Prune back the plant by one-third of its height to promote bushier growth and prevent it from becoming too tall and top-heavy.
Propagation of Oxalis polyphylla Jacq. var. alba T.M.Salter
Oxalis polyphylla Jacq. var. alba T.M.Salter can be propagated through several methods including division of rhizomes, stem cuttings, and seed propagation.
Division of Rhizomes
Division of rhizomes is the easiest and quickest method of propagating Oxalis polyphylla Jacq. var. alba T.M.Salter. This method involves carefully digging out the plant and separating the rhizomes into sections. The separated rhizomes can then be potted individually.
Stem Cuttings
Stem cuttings are another viable method of propagation for Oxalis polyphylla Jacq. var. alba T.M.Salter. This method involves taking cuttings from the stem of the plant and planting them in soil. The cuttings should have at least two nodes and be around 5 to 10 cm in length. The cuttings should be planted in well-draining soil and kept in a humid environment until they develop roots.
Seed Propagation
Seed propagation is a longer and more challenging method of propagating Oxalis polyphylla Jacq. var. alba T.M.Salter. The seeds should be sown on the surface of well-draining soil and kept moist until they germinate. Once the seedlings have reached a suitable size, they can be transplanted to individual pots.
Disease Management
Oxalis polyphylla Jacq. var. alba T.M.Salter is susceptible to various fungal and bacterial diseases. The common diseases that affect this plant include:
- Leaf spot: This is a common fungal disease that affects the leaves of the plant. It causes brown or black spots on the leaves, resulting in defoliation if not managed on time.
- Rust: Rust is another fungal disease that attacks the leaves, stems, and flowers of the plant. It causes yellow or brown spots on the plant, leading to stunted growth and premature death.
- Mildew: Mildew is a fungal disease that thrives in humid conditions. It causes powdery white spots on the leaves of the plant, leading to reduced photosynthesis and plant growth.
- Bacterial blight: This disease spreads quickly, causing water-soaked spots on the leaves. The spots soon turn brown or black and may lead to stunted growth or plant death.
The following are ways to manage these diseases:
- Pruning: Remove all infected leaves, stems, and flowers and dispose of them properly to avoid spreading the disease.
- Fungicides: Application of fungicides will control fungal diseases. Choose a product that is registered for use on Oxalis polyphylla Jacq. var. alba T.M.Salter, and follow the instructions for application.
- Cultural measures: Proper care of the plant, including regular watering, fertilization, and removal of dead plant material, helps increase the plant's resistance to these diseases.
- Plant resistance: Choose disease-resistant varieties and ensure you obtain high-quality planting material to avoid introducing diseases into your garden.
Pest Management
Oxalis polyphylla Jacq. var. alba T.M.Salter is not highly susceptible to pests, but some common pests that may attack this plant include:
- Spider mites: Spider mites are tiny pests that suck sap from the leaves, resulting in yellowing of leaves and stunted growth. They also produce webbing, which gives the plant a dusty appearance.
- Aphids: Aphids are small, sap-sucking insects that attack the young leaves of the plant. They cause leaf curling, stunted growth, and they also produce honeydew, which attracts ants and promotes fungal growth.
- Snails and slugs: These pests will eat holes in the leaves or completely devour the plant, leading to plant death.
The following are ways to manage these pests:
- Handpicking: Pick off snails and slugs by hand; aphids and spider mites can be dislodged with a strong jet of water to reduce their population.
- Biological control: Introduce natural predators such as ladybirds and lacewings that feed on aphids and spider mites. Also, nematodes can be used to control snails and slugs.
- Pesticides: Use pesticides as a last resort only if the pest population is overwhelming. Choose a product that is registered for use on Oxalis polyphylla Jacq. var. alba T.M.Salter, and follow the instructions for application.
