Light Requirements
Oxalis deserticola typically grows in areas with plenty of bright sunlight. Therefore, it is essential to place the plant in a position where it receives full or partial sunlight for about 4-6 hours a day. Lack of enough sunlight can result in the plant becoming leggy and producing few flowers.
Temperature Requirements
As the name suggests, Oxalis deserticola is mostly found in desert regions, meaning that it can withstand high temperatures. The plant can thrive in temperatures ranging from 18°C to 38°C. However, it is sensitive to frost, and temperatures below 5°C can cause it to wither and die.
Soil Requirements
Oxalis deserticola prefers well-draining soils with a mixture of sand, clay, and organic matter. The soil should have a slightly acidic pH ranging from 6.0 to 7.0. The plant can be grown in pots or in garden beds. If planting in a pot, ensure it has drainage holes, and use a potting mix with added perlite or sand to aid drainage. The addition of organic matter like compost can also help improve soil structure and nutrient availability.
Cultivation of Oxalis deserticola T.M.Salter
Oxalis deserticola T.M.Salter is native to the southwestern part of the United States and can be grown both indoors and outdoors.
Watering Needs
This plant requires moderate watering and can tolerate drought conditions. It is best to water this plant when the topsoil feels dry to the touch. Overwatering can cause root rot, so it is essential to ensure that the soil is well-drained.
Fertilization
Oxalis deserticola T.M.Salter does not require frequent fertilization. However, it can benefit from a slow-release fertilizer during the growing season. This plant is adapted to thrive in low-nutrient soils, so overfertilization can lead to salt buildup in the soil.
Pruning
Oxalis deserticola T.M.Salter does not require regular pruning. However, it is essential to remove any yellow or dead leaves promptly. If the plant gets too leggy or sprawling, it can be lightly pruned to encourage bushier growth.
Propagation Methods of Oxalis deserticola T.M.Salter
Oxalis deserticola T.M.Salter, also known as Desert Wood Sorrel, is a drought-tolerant plant that is native to the southwestern United States. Propagation of this species can be easily done through various methods that are discussed below:
Seed Propagation
Seeds are the easiest and most common way to propagate Oxalis deserticola. The seeds should be collected from mature fruits, which are formed after the flowers have bloomed. They should be sown in a well-draining soil mixture, covered lightly with soil, and kept humid until the seedlings emerge. It takes about 2-3 weeks for the seeds to germinate.
Division
Oxalis deserticola can also be propagated through division, which involves separating the parent plant into several smaller sections and replanting them individually. This is typically done when the plant outgrows its current pot or when the plant becomes too large.
The best time to divide is in the spring, when new growth appears. To divide, remove the plant from its pot or ground, gently separate the roots, and replant the divided sections in a well-draining soil mix.
Cuttings
Cuttings of Oxalis deserticola can be rooted in the same way as with many other plants. The stem cuttings about 4 inches long should be taken from the parent plant, with a few leaves attached. Dip the cuttings in rooting hormone and then plant them in a well-draining soil mix. It can take 2-3 weeks for the cuttings to form roots.
Propagation of Oxalis deserticola T.M.Salter is easy and straightforward, and can be done through seeds, division, or cuttings. With proper care and attention, newly propagated plants can grow and flourish in any suitable environment.
Disease and Pest Management for Oxalis deserticola T.M.Salter
