The ideal soil for cultivation should be well-draining, loose, and rich in organic matter. The plants prefer full sun but can also grow in partially shaded areas.
Watering Needs of Oxalis blastorrhiza T.M.Salter
These plants require regular watering during the growing season, especially in hot and dry conditions. The soil should be kept moist but not waterlogged. However, it is essential to avoid overwatering, as it can lead to root rot and other problems.
Fertilization of Oxalis blastorrhiza T.M.Salter
These plants require regular fertilization to promote their growth and health. Fertilize the plant in early spring and again in midsummer with a balanced, slow-release fertilizer. Be sure to follow the instructions on the package to avoid over-fertilization.
Pruning of Oxalis blastorrhiza T.M.Salter
Pruning is generally not necessary or recommended for Oxalis blastorrhiza T.M.Salter plants. However, removing any dead or damaged stems or leaves can help promote the plant's health and appearance. It is also a good idea to deadhead the flowers regularly to encourage the growth of new blooms.
Propagation of Oxalis blastorrhiza T.M. Salter
Oxalis blastorrhiza T.M. Salter, commonly known as the "Bulbil Oxalis," is a bulbous plant that produces small, underground bulbs called bulbils, which can be used for propagation. Other propagation methods include seed germination and division of bulbs.
Propagation from Bulbils
The bulbils of Oxalis blastorrhiza can be harvested in the fall, after the foliage dies back. They should be stored in a cool, dry place until spring, when they can be planted in a well-draining soil mix. Bulbils should be planted at a depth of approximately 3-4 inches, with the pointed end facing up. The soil should be kept lightly moist but not waterlogged. New plants will emerge from the bulbils in spring or early summer.
Propagation from Seed
Seeds are another option for propagating Oxalis blastorrhiza. Sow the seeds in a well-draining soil mix and keep them moist. Germination can take several weeks to several months. Once the seedlings have two or three true leaves, they can be transplanted into individual pots or into the garden, if the weather is warm enough. Keep the soil moist but not waterlogged.
Propagation by Division
Oxalis blastorrhiza can also be propagated by division of bulbs. Dig up the bulbs in the fall, and gently separate them into smaller sections. Each section should have several "toes" and a good root system. Plant the sections in well-draining soil and keep them moist. New growth should emerge in the spring.
