Why are the old leaves of the rainbow arrowroot turning yellow?

1. Normal metabolism

The old leaves of the rainbow arrowroot turn yellow, which may be due to normal metabolism. After a period of care, the leaves underneath will naturally turn yellow. This is a normal natural phenomenon. There is no need to worry or interfere. Just pick off the old and yellow leaves underneath and continue with normal maintenance.

2. Lack of water

Rainbow arrowroot needs a certain amount of water to supplement its growth. If it lacks water for a long time, the leaves will be affected, causing the old leaves to gradually turn yellow from the bottom to the top and fall down, but the newly grown leaves are still normal, which can be observed. Be sure to pay attention to watering at ordinary times, add water according to the growth situation, and do not let the potting soil lack water. Make sure to water thoroughly each time, not too much or too little.

3. Too much fertilizer

It needs certain fertilizers during its growth process to maintain normal growth. If the concentration of fertilizer applied is too high, the roots will find it difficult to absorb it, and it will accumulate at the roots, causing the old leaves to turn yellow and fall off. You need to stop fertilizing immediately. You can also apply water to promote the outflow of fertilizer. If the situation is serious, you can replace the potting soil.
