A Detailed Guide to the Latest Planting Methods for Oxalis

Oxalis is also called sour grass. It has many varieties, with more than 900 known species. Its leaves are obcordate, its flowers are brightly colored, and its ornamental value is extremely high. It is deeply loved by many people, and large-scale cultivation has begun. In addition, the whole plant can be used as medicine, and it has the effects of clearing heat and promoting diuresis, cooling blood and dispersing stasis, and detoxifying and reducing swelling. So how should it be planted? Let us take a look at the detailed introduction below.

1. Land preparation

Oxalis likes to grow in loose, well-drained sandy soil. Soil that is too heavy and sticky is not good for its growth. Before planting, the land should be prepared and fertilized. Plow the soil 30-40cm, apply organic fertilizer and compound fertilizer, then break it up finely, rake it level, and compact it. Oxalis has a high water requirement, so drainage measures should be well prepared. The plot can be kept at a certain slope or made into ridges and beds, and drainage ditches can be dug to facilitate drainage.

2. Propagation

There are many varieties of oxalis, but the ones we mainly see are yellow-flowered or purple-flowered oxalis, which can be propagated by small bulbs or cuttings. Every year in summer, when the temperature rises, the aboveground plants gradually turn yellow and wither. At this time, the underground bulbs can be dug out and stored in a cool place, then planted after the weather turns cool in autumn. When planting, place the bulb sprout upward, then cover with soil. The thickness of the soil layer is generally 1-2 times that of the bulb, then water and keep the soil moist. Keep the temperature above 5°C and wait for emergence.

3. Field management

After the seedlings emerge, management should be strengthened. First is water: it should not be watered too much, only kept moist for a long time. Generally, water again after the soil has dried completely. If watered too much, the bulbs will rot. Oxalis likes potassium fertilizer. During the seedling stage, some decomposed organic fertilizer can be applied appropriately, without too much, to promote its growth. In addition, oxalis likes an environment with sufficient light, so sufficient light should be provided, but exposure to strong sunlight should be avoided. Under sufficient light, the plants grow quickly, bloom more, and the yield is also higher. With insufficient light, the plants are weak, have fewer flowers, and the yield is lower.

4. Pests and diseases

The main pests and diseases are aphids and rust. Aphids generally reproduce in autumn and spring, will eat the leaves clean, and in severe cases cause plant death. They can be controlled by spraying imidacloprid. Rust is a fungal disease. The main causes are soil that is too moist or long periods of rainy weather. If not treated in time, it will cause yellow leaves or death of the plants. When the disease is found, the diseased plants can be pulled out and taken out of the field, then the diseased holes can be disinfected. If the disease has already spread, spray Cuibei for control.
