The plant needs at least 6 hours of light per day to grow and develop properly. This makes it ideal to grow in a location with a south-facing window or under grow lights.
Temperature Requirements
Oxalis helicoides var. alba prefers warm, humid environments. The ideal temperature range is between 60 to 75 degrees Fahrenheit (15 to 24 degrees Celsius). It is important to keep the plant away from cold drafts and high-temperature fluctuations as it may cause the plant to wilt or damage the foliage. Furthermore, ensure to maintain a constant temperature around the plant for optimal growth.
Soil Requirements
For Oxalis helicoides var. alba to grow properly, it requires well-draining, fertile soil. The soil should be a mixture of peat moss, perlite, and coarse sand to allow for water drainage and proper aeration. Additionally, the soil pH should be between 6.0 to 7.0, which is slightly acidic to neutral. It is also best to keep the soil evenly moist, but not waterlogged, to prevent the plant's roots from rotting.
Cultivation Methods
Oxalis helicoides T.M.Salter var. alba T.M.Salter, commonly known as the Spiral Oxalis, is a plant that is native to South Africa. It belongs to the Oxalidaceae family and is a member of the Oxalis genus. When it comes to cultivation, this plant is relatively easy to care for and can be grown in indoor or outdoor settings.
For planting, it is essential to select a pot or container that is large enough to allow the plant to grow and develop. The soil should be well-draining to avoid waterlogging, and a mix of peat, soil, and sand is ideal. Planting should be done during the spring and summer months when the plant is in its active growth phase. The ideal temperature range for the plant is between 60-75°F.
Watering Needs
When it comes to watering, Oxalis helicoides var. alba prefers to be kept moderately moist. The plant does not tolerate soggy soil well. Overwatering can cause root rot and other problems, so it's essential to let the top inch of soil dry before watering again. The plant can withstand periods of drought but will do best if kept consistently moist. It is also essential to water the plant from the bottom to avoid getting water on the leaves, which can cause fungal diseases.
Fertilization
During the active growing season, fertilizer applications are recommended every two weeks using a balanced, water-soluble fertilizer. The plant is not a heavy feeder, so care should be taken not to over-fertilize. When the plant enters its dormant phase in the fall, fertilizer applications should be discontinued.
Pruning
Pruning is not typically necessary for Oxalis helicoides var. alba. However, it can be helpful to remove any dead or wilted leaves periodically. This will encourage new growth and help to keep the plant looking healthy and attractive. If the plant becomes too leggy or unruly, it can be trimmed back by up to one-third of its overall size. Regular trimming will help to keep the plant bushy and compact.
Propagation of Oxalis helicoides T.M.Salter var. alba T.M.Salter
Oxalis helicoides T.M.Salter var. alba T.M.Salter can be propagated through several methods such as division, cuttings, and seeds.
Division
Division is the easiest method for propagating this plant. You can divide the plant during spring or autumn when it is actively growing. Gently dig the soil around the plant and remove it from the ground. Carefully divide the tubers into several pieces. Ensure you leave a few healthy roots and shoots on each piece. Plant them in well-drained soil, and ensure they receive adequate moisture during the growing season.
Cuttings
You can also propagate Oxalis helicoides T.M.Salter var. alba T.M.Salter through stem cuttings. Take cuttings from healthy, mature plants during spring or summer. Cuttings should be 5-8 cm long and have a few leaves. Dip the cut end in rooting hormone and plant them in a well-draining soil mix. Keep the soil moist and ensure they receive bright, indirect light. Cuttings usually take between 4-6 weeks to root.
Seeds
Oxalis helicoides var. alba can be propagated through seeds; however, this method can be challenging as this plant does not produce seeds regularly. Collect seeds from the parent plant when the seedpods are dry and have turned brown. Sow the seeds in well-draining soil, and lightly cover them with soil mix. Keep the soil consistently moist and ensure they receive bright, indirect light. Germination can take up to several weeks, and it may take several years for the plant to reach maturity.
