Propagation of Oxalis flaviuscula T.M.Salter
Oxalis flaviuscula T.M.Salter is a small, herbaceous plant that is native to Brazil. It is commonly known as "yellow wood sorrel" because of its yellow flowers and clover-like leaves. The plant is easy to propagate and can be grown from both seeds and cuttings.
Propagation by Seeds
The seeds of Oxalis flaviuscula T.M.Salter can be collected from mature plants and sown directly in soil. The best time to collect the seeds is when the pods turn brown and start to split open. The seeds should be stored in a dry and cool place until they are ready to be sown.
To sow the seeds, prepare a seedling tray or small pots with well-draining soil. Sow the seeds thinly on the soil surface and cover lightly with soil. Keep the soil moist and place the tray or pots in a warm and bright location, but out of direct sunlight. The seeds should germinate within two to four weeks.
Propagation by Cuttings
Oxalis flaviuscula T.M.Salter can also be propagated by stem cuttings. Take stem cuttings of about 5-7 cm in length from a healthy plant. Remove the lower leaves from the cutting and dip the cut end in rooting hormone powder.
Prepare a pot with well-draining soil and make a hole in the soil with a pencil. Insert the cutting into the hole and gently firm the soil around it. Water the cutting to settle the soil and place the pot in a warm and bright location, but out of direct sunlight. Keep the soil moist but not waterlogged.
The cutting should start to root within two to four weeks. Once the cutting has rooted, it can be transplanted to a larger pot or to the garden.
