Propagation Methods
Oxalis corniculata L. var. ringoettii (De Wild.) R.Knuth, commonly referred to as creeping wood sorrel, is propagated through several methods. The following are some of the most effective propagation methods:
Seeds
One of the simplest methods to propagate Oxalis corniculata L. var. ringoettii is through seeds. The seeds should be sown in well-draining soil and covered with a thin layer of soil. The soil should be kept moist, and the seeds will germinate within 1-2 weeks. When the seedlings reach 3-4 inches tall, transplant them to larger containers or directly to the garden bed.
Cuttings
Cuttings are another propagation method for the Oxalis corniculata L. var. ringoettii plant. Cuttings should be taken from healthy stems and placed in moist soil. Place the container in a bright, well-lit area out of direct sunlight. The cuttings will begin to root within 2-3 weeks. Transplant the cuttings to larger containers or directly to the garden bed when they have established roots and are growing well.
Division
Division is an effective propagation method for mature plants. With a sharp knife or shears, divide the plant into smaller sections, each with an equal amount of root and foliage. Plant each division in a well-draining soil mix, and keep the soil moist. It is best to perform division in the spring when the plant is actively growing.
Bulbs
Oxalis corniculata L. var. ringoettii produces small bulbs that can be harvested and replanted to propagate new plants. Simply remove the bulbs from the plant and plant them in well-draining soil, covering them with a thin layer of soil. Keep the soil moist, and the plants will begin to grow within a few weeks.
