Care methods for home potted purple sorrel

Temperature

Oxalis likes a warm and humid environment, and the most suitable growth temperature is 16 ~22℃.

Not cold tolerant, plants stop growing below 10℃ and leaves wither at 0℃. However, as long as the underground rhizomes are not frozen, new leaves can still sprout and grow normally in April next year. In winter, the leaves should be kept in normal condition and the temperature should be kept above 5℃.

It is not resistant to high temperatures. When the temperature exceeds 35℃, the leaves curl, grow slowly, and enter a dormant period. Spray water on the leaves in time, provide shade and enhance ventilation.

Light

Oxalis needs sufficient light to grow, and it must grow in full sun or half sun.

In spring and autumn, it should receive sufficient sunlight. Too much shade will cause the leaves to be dull, the petioles to be thin, and the plant shape to be scattered. However, you should also avoid direct exposure to strong light and provide adequate shade from 5 to 9 months to avoid sunburn.

Oxalis has a strong phototaxis. During maintenance, it should be placed on the balcony or windowsill. The position of the plant should be changed frequently to allow it to receive even light all around.

Watering

Tolerant of drought, but prefers a moist environment.

During the growth period, keep the pot soil moist and adhere to the principle of "don't water it if it's dry, water it thoroughly". During the high temperature season in summer, the plants enter the dormant period. At this time, water should be sprayed to keep the pot soil slightly moist. In winter, when the temperature drops below 10℃, watering should be done dry rather than wet to prevent the bulbs from rotting.

Proper exposure to rain will help growth and development. However, water must be drained in time. Accumulated rain in the pot soil will cause the leaves to rot and cause the plants to die in pieces.

Environmental humidity

Oxalis likes a humid environment. When the growing environment is dry, spray water around it in time to increase the humidity.

Fertilization

When potting, apply enough base fertilizer.

During the growing season, in order to make the plants grow robustly and ensure the leaves are thick and shiny, apply nitrogen, phosphorus and potassium compound fertilizer once a month. Pay attention to the concentration when fertilizing. Excessive concentration will burn the bulbs and affect growth. Stop fertilizing in July to August.

Be careful not to apply a single fertilizer, especially nitrogen fertilizer, which will cause the leaves to turn from purple to green, affecting the viewing. When fertilizing, do not splash liquid fertilizer on the leaves, as this may cause leaf diseases.

Pruning

The following three situations require pruning:

When the plant grows too vigorously, the denser leaves should be removed in time to improve ventilation and light transmission conditions and promote growth.

Of course, in daily maintenance, yellow leaves should be removed in time to reduce the occurrence of diseases and insect pests.

Flower cultivation pays attention to beauty. When the petiole is too long or the plant shape is not beautiful, you can cut the leaves again to let them grow new leaves.

Repotting

Oxalis grows quickly and should be repotted once every spring. It is best to change the soil when repotting. Loose, fertile, medium-acidic soil with good drainage is preferred.
