How to solve the problem of yellowing leaves

When growing flowers at home, healthy flowers and plants grow vigorously and have green branches and leaves, but if yellow leaves appear, it will greatly affect the appearance. Let’s learn how to solve the problem of yellowing leaves of flowers.

1. Improper watering

Too much or too little watering can easily cause the leaves of the plant to turn yellow. This is mainly because the potting soil is damp for a long time, causing soil hypoxia and root rot, which hinders the plant's normal absorption and respiration of water and causes the leaves to turn yellow. Drought and water shortage can also cause the leaves to become dull, old and yellow.

Solution: If you water too much, you should immediately control watering and stop fertilizing. If the situation is serious, you need to replace the potting soil in time and cut off the rotten roots. If you water too little, you need to water in small amounts and spray water on the leaves of the plant.

2. Lack of light

Flowers and potted plants basically need sunlight. Even shade-loving plants cannot be kept in a place without any light all year round. It needs a certain amount of diffuse light. If it is placed in a hidden environment for a long time, the leaves will not get enough sunlight, which will also cause yellowing.

Solution: If the flowers and leaves turn yellow due to insufficient light, you need to move the plant to a sunny location for maintenance.

3. Improper fertilization

Improper fertilization, too much or too little fertilization can also cause yellowing of leaves. If too much fertilizer is applied, it will easily cause nutritional excess, and the plants will not be able to fully absorb nutrients, thus causing fertilizer damage. Long-term lack of fertilizer, especially nitrogen fertilizer, will cause the plants to be malnourished and the leaves to turn yellow.

Solution: Usually follow the principle of "applying thin fertilizers frequently". The concentration should not be too high, and it is best to water once the next day after applying the fertilizer to dilute the concentration.

4. Poor ventilation

For plants, ventilation is also an essential factor in the growth environment. If the ventilation conditions are poor, the flowers and leaves will easily wilt and turn yellow, or even be infected with bacterial diseases.

Solution: If the yellowing of flowers and leaves is caused by poor ventilation, you need to move the plant to a ventilated place for maintenance.

5. Soil pH

Different flowers and plants have different growth habits. Some prefer acidic soil , while others prefer alkaline soil. If the soil pH is not suitable, it will inevitably cause poor plant growth and the leaves will lose their green color and turn yellow.

Solution: Plant the flowers in soil suitable for their growth. For example, flowers that like acid should be planted in acidic soil; flowers that like alkaline soil should pay attention to applying calcium, magnesium and phosphate fertilizers to prevent the soil from becoming "acidic".

6. Temperature reasons

Too high or too low temperatures are also not conducive to plant growth. If the room temperature is too low in winter, the plants are likely to suffer from frost damage, causing the leaves to turn yellow. If the room temperature is too high, the transpiration of the plant will be too strong, and the roots will not be able to normally supply the leaves with water and nutrients, which will also cause the leaves to turn yellow.

Solution: Generally speaking, most plants can grow normally at temperatures between 15 and 25 degrees. Therefore, we should pay attention to temperature changes in daily maintenance, keep warm in winter, and pay attention to cooling and shading in summer.

7. Infection with bacteria

If a large number of yellow spots appear on the leaves of plants in your home and they continue to expand and worsen, you must be alert, as this indicates that they are likely infected with bacteria.

Solution: Prune the branches and leaves infected with the bacteria promptly, clean them, and isolate them from other healthy plants to avoid contaminating other plants. Move them to a well-ventilated and well-lit place, and spray them with appropriate fungicides promptly.

That’s it
