Light Requirements
Oxalis psilopoda Turcz. prefers to grow in partial to full shade. It cannot tolerate direct sunlight for extended periods and might suffer from sunburn or drying out. A location with filtered light, such as under a tree canopy or near a north-facing window, is ideal for this plant.
Temperature Requirements
The ideal temperature for growing Oxalis psilopoda Turcz. is between 65°F to 75°F (18°C to 24°C). It can withstand cooler temperatures as low as 50°F (10°C) and slightly warmer temperatures up to 80°F (27°C) but not for extended periods. Frost can damage or kill the plant, so it is preferable to keep it indoors during the winter season if you experience those conditions.
Soil Requirements
Oxalis psilopoda Turcz. does well in well-draining, loose soil that is rich in organic matter. A mixture of peat moss, perlite or vermiculite, and sand is ideal. The pH of the soil should be slightly acidic, around 6.0 to 6.5. Avoid using heavy soil or those that tend to hold water for long periods, such as clay soils.
Cultivation Methods
Oxalis psilopoda Turcz. is a small, easy-to-grow flowering plant that can be grown both indoors and outdoors. It prefers well-draining soil and can thrive in full sun or partial shade. The plant prefers a slightly acidic soil with a pH range of 5.5 to 6.5. The seeds can be sown in early spring or fall, and the plant can be propagated from cuttings as well.
Watering Needs
Oxalis psilopoda Turcz. requires moderate watering, and the soil should be kept moist but not waterlogged. Overwatering can lead to root rot and cause damage to the plant. Watering should be done when the top layer of soil feels dry. In summer, the frequency of watering may need to be increased due to the higher evaporation rate.
Fertilization
The plant requires regular fertilization to encourage blooming and healthy growth. A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium can be used every two weeks during the growing season. Over-fertilization can lead to issues such as salt buildup and root burn, so it's essential to follow the instructions on the fertilizer package.
Pruning
Oxalis psilopoda Turcz. does not require frequent pruning, but trimming can help maintain the plant's shape and promote blooming. Deadheading is essential to prevent the plant from producing seeds and to encourage the growth of new blooms. It's best to prune the plant in early spring before new growth appears.
Propagation of Oxalis psilopoda Turcz.
Oxalis psilopoda Turcz., commonly known as pink wood sorrel, is a herbaceous flowering plant that belongs to the family Oxalidaceae. It is widely cultivated for its attractive pink and white flowers and deep-green foliage. Propagation of this plant can be done through various methods, and some of them are discussed below.
Propagation by seeds
Propagation by seeds is a cost-effective method for raising Oxalis psilopoda. Sow seeds directly into the soil in spring or fall. For indoor sowing, sow the seeds about six to eight weeks before the last frost. Cover the seeds lightly with soil and water them well. Place the seed tray in a warm and bright place, but avoid direct sunlight. Seeds usually germinate within two weeks.
Propagation by division
Propagation by division is a simple and effective way of multiplying Oxalis psilopoda plants. Gently dig up the mature plants, and carefully separate the small rosettes using a clean and sharp knife. Ensure that each rosette has some healthy roots. Plant the rosettes in well-draining soil and keep them moist until they establish. Division is best done during the plant's dormant period, which is in summer or early fall.
Propagation by cuttings
Propagation by cuttings is another method of propagating Oxalis psilopoda, which is ideal for those who want a large number of plants in a short period. Take cuttings from the mother plant during its active growth period, which is in spring or summer. Cut off a 4-inch-long stem, remove the lower leaves, and make a clean cut at the base of the stem. Dip the cut end in rooting hormone and plant it in a container filled with well-draining soil. Keep the soil moist and place the container in a bright place, but avoid direct sunlight.
In conclusion, Oxalis psilopoda Turcz. can be propagated through various methods such as seeds, division, and cuttings. Each of these methods is simple, cost-effective, and practical for gardeners with different experience levels.
