How to deal with houseplants that often have yellow leaves

During the growth of flowers and plants, yellowing leaves often occur, and the cause is mostly improper cultivation and management. Too much or too little water, too strong or too weak sunlight, and too much or too little fertilizer can all cause leaves to turn yellow, but the yellowing conditions differ, so the causes should be carefully observed and analyzed, and management should be carried out promptly.

1. Water yellowing: young leaves are dull yellow and lack luster, old leaves show no obvious change, the stems are thin and yellow-green, and new shoots shrink and stop growing, indicating overwatering. Take the plant out of the pot, place it in a ventilated and shady spot to let the soil ball dry on its own, then put it back into the pot.

2. Drought yellowing: the yellowing from lack of water is different from the yellowing from too much water. The yellowing from lack of water shows withered and dry leaf tips or edges, and old leaves turn yellow and fall off from the bottom upward, but new leaves grow relatively normally. Just be careful to water thoroughly and sufficiently.

3. Scorch yellowing: strong direct sunlight shining on some shade-loving flowers and plants (such as spider plants, hostas, etc.) easily causes the leaf tips and leaf edges to wither, and yellow spots appear on the sun-facing parts of the leaves. Just move them to a shady place.

4. Light-deficiency yellowing: when placed in a shaded environment for a long time, the leaves cannot get enough sunlight and cannot form chlorophyll, so the whole plant's leaves turn yellow and then fall off. Supplementing light can prevent this problem.

5. Fertilizer yellowing: yellowing of flowers and plants caused by excessive fertilization or too high concentration shows dry brown tips on new leaves; generally the leaf surface is thick and lacks luster, and is uneven and not spread out, while old leaves scorch yellow and fall off. Fertilization should be stopped immediately, and in severe cases, a large amount of clean water should be used to wash out part of the fertilizer.
