What to do if the leaves of Oxalis turn yellow

Causes of yellowing

Lack of water

Oxalis likes a warm and humid environment, especially during the growing season, it needs a lot of water, and usually needs to be watered once a day. If there is too little water, the roots of the plant cannot store nutrients, and the leaves lack water. If exposed to sunlight, the moisture in the leaves evaporates, the plant becomes weak, and the leaves start to turn yellow and wilt downwards until the entire plant dies.

Excessive sunlight or lack of light

If Oxalis is placed in a semi-shaded place and suddenly moved to the sun for exposure, the leaves will be burned and turn yellow, and the entire plant will gradually wilt. Another situation is that if the plant is placed indoors for a long time and lacks light, the leaves of the plant will turn yellow.

Leaf spot

Leaf spot mainly harms the leaves, causing brown spots to appear on the leaves and causing the leaves of the plant to dry up.

Prevention and treatment measures

Water replenishment by immersion basin method

Usually, the reason why plants lack water is not because of lack of watering, but because of incorrect watering method. The immersion method should be used. Find a small basin, fill it with 3 to 4 cm of water, and place the Oxalis basin in it. Water seeps through the vent holes at the bottom of the flowerpot, and the leaf stems will recover a little in about half a day.

Proper lighting

Oxalis is very demanding in terms of sunlight, and a little more or less will cause problems. Place the plant on a well-ventilated balcony so that it can receive sunlight every day. Adjust the angle of the pot appropriately to ensure even sunlight exposure. When the sunlight is strong, you can put a plastic bag on the flower pot to weaken the sunlight.

Drug prevention

When watering and supplementing light do not improve the condition, you can spray copper noble suspension or benomyl solution once every 2 to 3 days. There will be improvement after 3 to 5 times.
