What if the leaves of hibiscus are yellow?

One. Too much water

In general, we have to find out the cause of the problem. The reason why the leaves turn yellow is probably because the owner irrigates too much water to the plant, so that the soil in the basin is too wet for a long time, so there will be a lack of oxygen in the soil, and the roots can not breathe. It is easy to cause part of the roots to rot, so the plant is unable to absorb nutrients and water, and the leaves will turn yellow and fall. In general, this situation is shown in that the softer leaves first turn pale yellow, and then the old leaves turn yellow again. At this time, we should control the moisture, stop fattening temporarily, and help loosen the soil to restore it to a breathable state.

2. Too little moisture

If the above water is not too much, then it may be due to too little, the plant is dehydrated. Forgetting to water or watering only half of the water for a long time, the top is wet and the bottom is still dry, which will greatly affect the plant's absorption of nutrients, cause the leaves to become dim and dull, and the leaves will wither downward. This situation is shown in that the old leaves below begin to age, and then the leaves turn yellow and wither from the bottom to the top. At this time, we should add a little bit of water to it, so that it can gradually return to its normal state before watering normally.

Three. No fat

If you haven't added some ammonia fertilizer to it for a long time or haven't changed the basin soil for a long time, then the ammonia and other substances in the soil will be lacking, and the leaves of the plant will become thin and yellow. At this time, you should change the basin and soil in time, and then gradually add some fertilizer to it.
