Reduce light: After the leaves of the green lotus pillar turn yellow, it should first be maintained in another position, and changed to a cool and ventilated place to avoid direct sunlight.
Pruning yellow leaves: Cut off the dead yellow leaves to avoid the spread of pests and diseases.
Replenish water: Dry yellow needs to be watered in time, and iron products such as nails can also be put into the water to increase the iron element in the water.
Replenish nutrients: Regular application of nitrogen and potassium fertilizer promotes the return of leaves to emerald green.
First, reduce the light
When the light is too strong, the leaves of the green lotus will be sunburned by the sun, and then the yellowing of the leaves will occur. Therefore, after finding that the leaves are yellow, the first thing to do is to change the breeding environment and move the green lotus to a cool and ventilated place.
Second, prune the yellow leaves
After changing the breeding environment, and then use scissors to prune off those yellow branches and leaves, the green leaves may also be because the leaves are infected with diseases and insect pests, and pruning off the yellow leaves can prevent infection with other healthy leaves. If it is found that the leaves are indeed yellow due to disease during pruning, they can be treated with the corresponding agent.
Third, replenish water
If it is not watered for too long, the leaves will turn yellow due to lack of water, and the lack of iron in the soil will also cause iron deficiency xanthophyll disease. Therefore, after changing the maintenance position and pruning off the yellow leaves, it is necessary to add some iron and water. Iron products such as iron nails can be soaked in water for one night, and then irrigated with these iron-rich waters, which can be restored by placing them in a cool and ventilated place for a period of time.
Fourth, supplement nutrients
Applying some nitrogen and potassium fertilizer every month can promote rapid plant growth and the leaves will return to their former emerald green. However, after applying the fertilizer, remember to irrigate it every other day to allow the fertilizer to penetrate completely into the soil.
