1. Water yellowing. Leaf yellowing caused by long-term watering is manifested by the young leaves turning yellow without luster, while the old leaves show no significant changes, the roots are thin and yellow-green, the new shoots shrink and do not grow, and watering should be controlled. In severe cases, remove the pot, let the soil dry in a shaded place, and then repot.
2. Drought yellowing. Leaf yellowing caused by lack of water or insufficient watering. The old leaves turn yellow and fall from the bottom up, but the new leaves generally grow normally. The amount and frequency of watering should be increased appropriately.
3. Fertilizer yellowing. Excessive or overly concentrated fertilization causes the top of the new leaves to turn brown, the tip of the old leaves to dry and turn yellow and fall off, although the leaf surface is thick and glossy, most of them are uneven. Stop watering with fertilizer or rinse the fertilizer with clean water.
4. Fertilizer deficiency yellowing. The pot plant has been watered without fertilizing for a long time, or the pot has not been changed for many years, the roots become tangled, the plant does not get fertilizer, causing the leaves to turn yellow. In addition to changing the pot in time, thin and frequent fertilization is recommended.
5. Scorching yellow. Shade-loving pot plants and foliage plants, such as吊兰 (Spider plant),万年青 (Rohdea), 一叶兰 (Aspidistra), 玉簪竹芋 (Calathea), etc., often show yellow leaf tips when exposed to strong sunlight. They should be placed in a shaded area.
6. Alkali yellowing. Acidic soil-loving flowers, such as azalea, gardenia, camellia, osmanthus, and white magnolia, often cause leaves to turn from green to yellow or even fall off if the pot soil or water is alkaline. In addition to using acidic nutrient soil, you can use alum fertilizer water or a 0.2%-0.5% ferrous sulfate solution to spray, which can make the leaves turn from yellow to green.
7. Humid heat yellowing. Some flowers that are not heat and humidity tolerant may turn yellow due to hot weather, poor ventilation, and improper shading in the summer. For example, hanging bells and azaleas show this phenomenon in a stuffy and humid environment. Attention should be paid to ventilation and cooling, and the pot soil should not be too warm.
8. Whitening yellowing. Insufficient lighting for a long time causes a decrease in chlorophyll in the leaves, making the green color gradually disappear and showing a white disease. The plant can be moved to a sunny place to make the leaves slowly turn green.
9. In the cold winter, if the indoor temperature is low, some cold-sensitive flowers, such as white magnolia, Guangdong evergreen, and poinsettia leaves, will also turn yellow and fall off. In addition, flowers affected by diseases and pests can also cause yellow leaves and fall off. If only a few leaves at the bottom of the plant turn yellow and fall off, it is normal.
