What to do when the leaves of Philodendron 'Golden Diamond' turn yellow? Causes and solutions

Philodendron 'Golden Diamond' is deeply loved by plant enthusiasts for its outstanding indoor air-purifying effect and excellent ornamental value, making it a very good foliage plant. It has strong vitality, and as long as it is cared for properly, it can generally be grown very well. But if it is not cared for correctly, even the easiest potted foliage plant will develop problems. Take the phenomenon of yellowing leaves and leaf drop in Philodendron 'Golden Diamond', for example - it is mostly caused by improper care. So what should be done when the leaves of Philodendron 'Golden Diamond' turn yellow?

Below, the editor shares the causes and treatments for yellowing leaves in Philodendron 'Golden Diamond':

1. Overwatering

If a potted Philodendron 'Golden Diamond' is watered too much, it easily causes its young leaves to turn dull yellow and lose their luster, while the old leaves show no obvious change in growth. The stems become thin and long and appear yellow-green, and newly sprouted shoot tips shrivel and stop growing.

Solution: Overwatering naturally requires drainage. You can first take the plant out of the flower pot, then place it in a cool, ventilated spot. After the potting soil dries out, replant the plant back into the pot.

2. Long-term lack of water

Long-term lack of water is another important cause of yellow leaves in Philodendron 'Golden Diamond'. The yellowing from lack of water is clearly different in color from the yellowing caused by overwatering. When yellowing is due to lack of water, the leaf tips and leaf edges will appear dry and yellow, while the old leaves will turn withered yellow and fall off, and the new leaves grow relatively normally.

Solution: In this situation, the plant should be watered promptly, and it needs to be given sufficient water - just water it thoroughly.

3. Insufficient light

If Philodendron 'Golden Diamond' is kept in a shaded environment, because it cannot get the light needed for photosynthesis for a long time, it naturally cannot produce chlorophyll, and the plant's leaves will turn yellow and then fall off.

Solution: Move the plant promptly to a place with sufficient light so that it can fully receive light to promote photosynthesis and restore normal growth. But avoid direct strong light or sun exposure, especially in summer.

4. Overfertilizing

Many plants suffer fertilizer burn from overfertilizing, resulting in yellowing leaves and leaf drop. Philodendron 'Golden Diamond' is no exception. It mainly shows as the tips of newly sprouted leaves turning dry and brown, with the leaves being thick and lacking luster, uneven, and unable to unfurl, while the old leaves turn scorched yellow and drop off.

Solution: In this situation, what we need to do is immediately stop fertilizing, and at the same time rinse with clean water to dilute it, but drainage must be done well to prevent water accumulation in the pot.

5. Long-term lack of fertilizer

During the care of Philodendron 'Golden Diamond', if you want it to grow quickly, you need to supplement nutrients in a timely manner. If it effectively receives nutrient supplementation over the long term - or rather, if it lacks it - the plant's leaves will show yellowing due to lack of fertilizer.

Solution: Because the potting soil lacks nutrients for a long time, it will naturally become compacted. In addition to loosening the soil in time, you need to spray the plant with a dilute liquid fertilizer at the right time. It is recommended to follow the principle of frequent application of thin fertilizer, and you can appropriately add some alum water when watering normally.

6. Improper pH

As everyone knows, based on the growth habits of Philodendron 'Golden Diamond', we know that it prefers slightly acidic soil. If the soil is on the alkaline side, especially in the north where this is more pronounced, the leaves will easily gradually turn yellow, and leaf drop may even occur.

Solution: To adjust the soil's pH, you can appropriately pour fermented, fully decomposed rice-washing water into the potting soil, or even use rainwater.
