Why is My Zz Plant Turning Yellow? A Comprehensive Guide with Expert Solutions
Why Is My Zz Plant Turning Yellow?
The ZZ plant may be turning yellow due to overwatering, which can lead to root rot and attract fungus gnats.
It is important to only water the ZZ plant when the soil feels dry to the touch and to plant it in a well-draining pot with drainage holes.
If overwatering is suspected, allowing the plant to dry out and placing it in a sunnier location may help.
Severely saturated soil may require repotting and removing rotted roots.
Underwatering can also cause yellowing, so thoroughly soaking the soil is necessary in this case.
Pest problems, such as aphids, spider mites, thrips, and mealybugs, can lead to yellowing.
Treating them with neem oil or insecticidal soap can help.
Excessive sun exposure can also cause yellowing, so placing the ZZ plant in shadier areas is recommended.
Removing yellow leaves is advised, and fertilization is not necessary if the plant is repotted annually.
However, if fertilizing, a balanced succulent fertilizer should be used.
Key Points:
- Overwatering can cause ZZ plant to turn yellow, leading to root rot and attracting fungus gnats
- Water the plant only when the soil feels dry to the touch and use a well-draining pot with drainage holes
- If overwatering is suspected, allow the plant to dry out and move it to a sunnier location
- Severe saturation may require repotting and removal of rotted roots
- Underwatering can also cause yellowing, so thoroughly soak the soil in this case
- Yellowing can be caused by pests such as aphids, spider mites, thrips, and mealybugs, treat them with neem oil or insecticidal soap
- Excessive sun exposure can cause yellowing, so place the plant in shadier areas
- Remove yellow leaves and fertilization is not necessary if the plant is repotted annually, but if fertilizing, use a balanced succulent fertilizer.
Did You Know?
1. The ZZ plant (Zamioculcas zamiifolia) is native to drought-prone regions of Eastern Africa, particularly Tanzania and Zanzibar.
2. One possible reason for a ZZ plant turning yellow is overwatering. These plants prefer to be kept on the drier side and can easily become waterlogged if given too much water.
3. Interestingly, the ZZ plant is named after its botanist discoverer, Gustav Wilhelm J. Zamioculcas.
4. The yellowing of a ZZ plant’s leaves can also be caused by too much exposure to direct sunlight. These plants thrive best in medium to low light conditions.
5. Did you know that the ZZ plant has the ability to purify the air? It is known for its efficient removal of toxins such as xylene, toluene, and benzene from indoor spaces.
Overwatering And Root Rot
One of the primary reasons why ZZ plants may turn yellow is overwatering. When these plants are watered excessively, it can lead to root rot, which in turn attracts fungus gnats. These little pests thrive in moist environments and can cause further damage to the plant. Therefore, it is crucial to ensure that the ZZ plant is not being overwatered.
Proper Watering Techniques
Proper watering techniques for ZZ plants
To prevent overwatering, it is important to understand the proper watering techniques for ZZ plants. These plants should only be watered when the top inch of the soil feels dry to the touch. This indicates that the plant needs water. However, if the soil feels moist, it is best to hold off on watering until it dries out. By following these guidelines, you can avoid the risk of root rot and yellowing leaves.
Importance Of Well-Draining Pots
The type of pot in which the ZZ plant is planted plays a crucial role in preventing yellowing leaves. It is recommended to use a well-draining pot with drainage holes. This allows excess water to escape, preventing the soil from becoming waterlogged. The drainage holes provide an outlet for excess moisture, reducing the risk of root rot and maintaining the plant’s health.
Drying Out And Sunnier Locations
If you suspect that overwatering is the cause of your ZZ plant’s yellowing leaves, it is crucial to allow the plant to dry out. Cease watering and let the soil dry completely before watering again. In addition, consider moving the plant to a sunnier location.
ZZ plants thrive in bright, indirect light, and placing them in a sunnier spot can help regulate moisture levels and promote healthier growth.
- To improve the health of your ZZ plant:
- Allow the plant to dry out between waterings
- Move it to a sunnier location for better light
- Regularly check soil moisture to avoid overwatering
Sometimes, too much water can be harmful to plants.
Repotting And Removing Rotted Roots
In severe cases of root rot, it may be necessary to repot the ZZ plant. This process involves carefully removing the plant from its current pot, inspecting the roots for signs of rot, and trimming away any affected areas. Once the plant is repotted in fresh, well-draining soil, it should be watered sparingly until it shows signs of new growth. Repotting and removing rotted roots can help revive the ZZ plant and prevent further yellowing.

Frequently Asked Questions
What do I do if my ZZ plant has yellow leaves?
If your ZZ plant has yellow leaves, the first step is to carefully assess its watering habits. Overwatering is often the culprit behind this issue, leading to drooping and even leaf loss. Allow the soil to dry out before watering and ensure the plant is potted in well-draining soil and a container with drainage holes. Adjusting these factors should help revive the plant and prevent further yellowing of the leaves.
What does an overwatered ZZ plant look like?
When a ZZ plant is overwatered, several visual signs become evident. The stalks of the plant become noticeably soft and mushy, losing their healthy green appearance and turning brown. In addition, the leaves of an overwatered ZZ plant start to yellow, indicating that they are being damaged by excess moisture. Another clear indication of overwatering is the dropping of leaves, as the plant tries to shed some of the excess water it is retaining. If you suspect overwatering, it is best to refrain from watering further and consider pruning the plant to remove any damaged parts.
Can yellow leaves turn green again?
After the chlorophyll is lost in a leaf, the plant typically discards it and starts retrieving nutrients from the leaf. Consequently, once the leaf transitions to a yellow hue, it is unlikely to revert back to green. However, certain instances of nutrient deficiencies may potentially enable the yellow color to transform back into green with appropriate treatment.
Does ZZ plant need sunlight?
ZZ plants do not require direct sunlight to thrive. In fact, they prefer indirect light as direct sunlight can potentially harm their leaves. With their ability to grow well under fluorescent lights, ZZ plants are well-suited for office and commercial spaces. In warmer regions, they can also be grown outdoors in areas with filtered light and soil that promotes good drainage. This adaptability to different light conditions makes ZZ plants a very forgiving and versatile choice for any indoor or outdoor space.
