Oxalis likes warm and humid environment, especially in the growing period, which needs a lot of water, and generally needs to be watered once a day. If there is too little water, the roots of plants can't store nutrients and the leaves are short of water. If the leaves are exposed to the sun, the water evaporates, the plants become weak, the leaves turn yellow and wither downward until the whole plant dies.

2. Insufficient exposure or light

If Oxalis is placed in a semi-shady place and suddenly moved to the sun, the leaves will burn yellow and the whole plant will wither gradually. In another case, if a plant is left indoors for a long time, its leaves will turn yellow.

3. Leaf spot disease

Leaf spot mainly harms leaves, and brown leaves appear on the leaves, which makes the leaves of plants dry up.

4. Preventive and control measures

Soaking basin method for replenishing water

In general, plants are short of water not because they are not watered, but because the watering method is wrong, so pot soaking method should be adopted. Find a small basin, hold 3~4 cm of water, and put the basin of Oxalis into it. Water seeps from the vent hole at the bottom of the flowerpot, and the leaves and stems will recover a little in about half a day.

5. Proper lighting

Oxalis has strict requirements for sunlight, and problems will occur if there is more or less. Put the plants on a well-ventilated balcony, receive light every day, and change the angle of the basin appropriately to ensure uniform sunlight. When the sun is strong, you can put a plastic bag on the flowerpot jacket to weaken the sun.
