The plant is rich in antioxidants and has been found to have anti-inflammatory properties, making it useful in treating various health conditions, such as stomach ulcers and some skin conditions.
However, it is important to note that the plant contains oxalic acid, which can irritate the skin and be toxic when consumed in large amounts. Therefore, it is not recommended for consumption, especially by pregnant women, nursing mothers, and young children.
Light Requirements
Oxalis aurea Schltr. thrives in bright, indirect light. Too much direct sunlight can scorch its leaves, while too little light can result in leggy growth and fewer flowers. It is recommended to place Oxalis aurea a few feet away from a south- or west-facing window to provide the ideal amount of light.
Temperature Requirements
Oxalis aurea Schltr. prefers temperatures between 65-75°F (18-23°C) during the day, and slightly cooler temperatures at night. It is crucial to maintain a consistent temperature and avoid drastic temperature changes, as this can negatively impact the plant's growth and cause stress.
Soil Requirements
Oxalis aurea Schltr. grows best in well-draining, slightly acidic soil with a pH range of 5.5-6.5. The soil should be kept moist, but not waterlogged. It is recommended to use a peat-based potting mix, which provides good drainage and proper moisture retention. Adding a layer of organic mulch on top of the soil helps to maintain proper moisture levels and adds nutrients to the soil.
Cultivation Methods for Oxalis aurea Schltr.
Oxalis aurea Schltr. is best grown in zones 9-11. However, it can also be grown indoors in pots. The plant requires well-draining soil for optimal growth. Hence, plant it in a well-drained soil mixture to ensure that the plant's roots do not remain waterlogged.
Plant the plant in an area with enough light, preferably in a position with morning sun and afternoon shade. If not possible, a bright filtered light should be sufficient.
When planting outdoors, plant the oxalis aurea bulbs outside in the fall. Plant them 2-3 inches deep and about 4 inches apart. For indoor plants, plant them in a potting mixture with a pH of about 6.1-7.5. The plants should be planted about 1-2 inches deep.
Watering Needs for Oxalis aurea Schltr.
The oxalis aurea Schltr. plant requires moderate watering. Allow the soil to dry out completely before the next watering. Overwatering will lead to root rot, and this may cause the plant's death.
When planting outdoors, water newly planted bulbs once, and then water them as the soil dries out. Indoors, water the plants once a week but ensure that the soil has dried out completely before watering again.
Fertilization of Oxalis aurea Schltr.
Oxalis aurea Schltr. tends to be quite heavy feeders. Therefore, it is advisable to fertilize at least once every two weeks. Use a balanced fertilizer with an N-P-K ratio of 10-10-10. When the plant starts flowering, switch to a high-potassium fertilizer to boost blooming.
When planting outdoors, the fertilizer should be added to the soil before planting the bulbs. For indoors, use a half-strength solution every two weeks.
Pruning Oxalis aurea Schltr.
Pruning is not required for this plant. However, removing the spent flowers will encourage the development of new blooms. When the plant starts to yellow, this may be a sign that it is going dormant. Allow the plant to die back naturally and then replant new bulbs. No pruning is required while the plant is in its dormant phase.
Propagation Methods for Oxalis Aurea Schltr.
Oxalis Aurea Schltr., commonly known as Golden Oxalis or Shamrock Vine, is a popular indoor plant widely grown for its beautiful foliage and distinct trumpet-shaped yellow flowers.
Propagation of Oxalis Aurea Schltr. can be achieved through:
1. Division
Division is the fastest and easiest way to propagate Oxalis Aurea Schltr. This method involves separating the plant into smaller sections and replanting each section in a new pot with fresh soil. The best time to divide the plant is during the growing season in spring or early summer.
To propagate through division, gently lift the plant out of the soil and gently pull apart the leaves and stems of the plant. Be careful not to damage the roots. Once separated, replant each section in its new pot with fresh soil and water thoroughly.
2. Stem Cuttings
Propagation through stem cuttings is also a popular method for Oxalis Aurea Schltr. This method involves taking a stem cutting from the plant and growing new roots on the cut end of the stem. The best time to take stem cuttings is during the growing season in spring or early summer.
To propagate through stem cuttings, cut a 3-4 inch section of stem from the plant just below a leaf node. Remove the bottom leaves of the stem, leaving only a few at the top. Dip the cut end of the stem in rooting hormone and plant it in a small pot with fresh soil. Water the soil well and keep the cutting in a warm, bright location. Roots should develop within a few weeks.
3. Seeds
Propagation through seeds is also possible but less commonly used for Oxalis Aurea Schltr. Seeds can be collected from mature plants and planted in small pots with fresh soil. However, this method is more time-consuming and requires more patience as seeds may take several weeks to germinate.
To propagate through seeds, collect the mature seeds from the plant and plant them in small pots with fresh soil. Cover the seeds lightly with soil and water the soil well. Keep the pots in a warm, bright location, and water regularly to keep the soil moist. Germination should occur within 2-3 weeks.
Propagation of Oxalis Aurea Schltr. is relatively easy, and any of the above methods can be used to create new plants that will produce the same beautiful foliage and trumpet-shaped yellow flowers as the parent plant.
