Oxalis is an evergreen shrub, mainly cultivated in the southern part of Guangdong, China. Oxalis flowers have a strong fragrance, and many flower enthusiasts grow Oxalis potted plants indoors. They are often placed by the windowsill in the bedroom or in the living room. This plant looks beautiful and also has medicinal value, such as beauty and health care. To cultivate Oxalis, one must know how to propagate it. Let's talk about the propagation methods of Oxalis.
I. Cutting Propagation
Most cutting propagations of Oxalis are done in spring and summer, with spring cuttings typically done in late March.
Spring Cutting Method: The shoots should be selected from two-year-old branches, with a length of about 12 centimeters. The lower leaves of the shoots should be cut off and a rooting hormone applied before inserting them into the seedbed. After cutting, it is necessary to provide appropriate shading and keep the soil moist.
Summer Cutting Method: The branches should be selected from the current year's semi-woody branches, with a length of about 8 centimeters. The cutting method is the same as in spring. The cutting substrate should be disinfected in advance.
II. Grafting Propagation
Grafting propagation is usually done in spring and autumn. Spring grafting should be done between March and April, while autumn grafting should be done between September and October.
The rootstock is usually chosen from Magnolia, and the grafting method often used is the cleft grafting method. First, select a high-quality one-year-old branch from the upper middle part of the mother plant, with two nodes and remove the leaves. Then, perform the cleft grafting as appropriate. After grafting, cover it with a layer of straw, leaving the top bud exposed and avoiding excessive watering. After four weeks, the scion will recover and grow new buds. At this time, the straw needs to be removed, and the buds on the rootstock should also be removed.
III. Seed Propagation
From late February to early March, Oxalis seeds can be sown. They can be sown immediately after collection or stored in sand.
When sowing, place the seeds directly in the flowerpot. After sowing, cover the seeds with a thin layer of soil, about 2 to 3 centimeters thick, and place the Oxalis potted plant in a semi-shaded environment. After a month, the Oxalis will sprout. After the seedlings emerge, with proper care, they can be transplanted in the following spring.
IV. Layering Propagation
Layering propagation is not limited by time, but April is the best time with the highest survival rate. For home cultivation of Oxalis potted plants, two or three plants are sufficient.
Select robust branches from two-year-old plants, with a length of 15 to 20 centimeters. Choose a good position for soil生根, then perform a ring剥皮 (ring bark) about 0.8 centimeters wide, reaching the xylem. Then, cover it with a plastic bag, tie it securely at the bottom, and fill it with moss and cultivation soil, leaving a hole at the top for watering and ventilation.
During the maintenance stage, maintain a certain humidity, and water the bag appropriately. After two months, it can root, and once the roots are established, it can be transplanted to a pot. After potting, place the Oxalis potted plant in a semi-shaded area for two weeks without fertilizing, and gradually increase sunlight exposure.
The above is a comprehensive introduction to how to propagate Oxalis flowers and the correct propagation methods, hoping to provide green plant enthusiasts with some knowledge about green plants.
