If you have a zz plant (Zamioculcas zamiifolia), you may have noticed that its leaves are turning yellow. This can be a sign of a problem with the plant and is important to address.
In this article, we will explore some of the common causes of yellowing leaves in zz plants and what you can do to fix the problem.
What is a zz plant?
Before we dive into the causes of yellowing leaves, let’s first talk a little bit about the zz plant itself. The zz plant is a popular houseplant that is known for its glossy, dark green leaves and its ability to thrive in a range of conditions.
It is native to eastern Africa and is known for its ability to withstand drought and low light levels.
Causes Of Yellowing Leaves In Zz Plants
There are several common causes of yellowing leaves in zz plants. Some of the most common include:
Overwatering
One of the most common causes of yellowing leaves in zz plants is overwatering. This happens when the soil in the pot stays too wet for too long, causing the roots to rot. To fix this problem, make sure you only water the plant when the top inch of soil is dry, and use well-draining soil.
Underwatering
On the other hand, if the soil in the pot becomes too dry, the leaves of the zz plant may turn yellow and droop. To fix this problem, make sure you water the plant regularly, making sure the soil is evenly moist but not soggy.
Poor Lighting Conditions
Zz plants need bright, indirect light in order to thrive. If the plant is not getting enough light, its leaves may turn yellow. To fix this problem, move the plant to a brighter location or consider using artificial lighting.
Nutrient Deficiencies
Yellowing leaves can also be a sign of a nutrient deficiency in the plant. For example, if the plant is not getting enough nitrogen, its leaves may turn yellow. To fix this problem, you can use a balanced fertilizer that contains all the necessary nutrients.
Pests
Pests such as aphids, mealybugs, and spider mites can also cause yellowing leaves in zz plants. To fix this problem, you can use a safe, organic pest control method or bring the plant to a professional for treatment.
How To Determine The Cause Of Yellowing In Zz Plants
There are a few steps you can follow to determine the cause of yellowing in your zz plant:
Observe The Plant Closely
Take a good look at the plant and try to notice any patterns or changes. For example, are the yellowing leaves concentrated in one area or are they scattered throughout the plant? Are the yellow leaves new or old? This will help you narrow down the possible causes.
Check The Soil Moisture
One of the most common causes of yellowing leaves in zz plants is improper watering. To check the moisture level of the soil, stick your finger about an inch into the soil. If it feels dry, the plant may be underwatered. If it feels very wet or soggy, the plant may be overwatered.
Examine The Lighting Conditions
Another common cause of yellowing leaves in zz plants is poor lighting. Check the location of the plant and consider whether it is getting enough light.
Zz plants prefer bright, indirect light, so if it is in a dark corner or far from a window, it may not be getting enough light.
Look For Pests
Pests such as aphids, mealybugs, and spider mites can also cause yellowing leaves in zz plants. To check for pests, gently turn the leaves over and look for any small insects or webs.
If you do find pests, you can try using a safe, organic pest control method or bring the plant to a professional for treatment.
Consider Nutrient Deficiencies
If you have ruled out the other causes and the yellowing leaves are still a mystery, it is possible that the plant is suffering from a nutrient deficiency. You can try using a balanced fertilizer that contains all the necessary nutrients to see if this helps.
Solutions For Yellowing Zz Plants
If you have a zz plant with yellowing leaves, here are some possible solutions to try:
Adjust Your Watering Habits
If the soil in the pot is too wet or too dry, this can cause the leaves to turn yellow. Make sure you are only watering the plant when the top inch of soil is dry, and use well-draining soil to prevent overwatering.
Move The Plant To A Brighter Location
If the plant is not getting enough light, its leaves may turn yellow. Consider moving the plant to a brighter location or using artificial lighting to help it get the light it needs.
Use A Balanced Fertilizer
If the plant is suffering from a nutrient deficiency, you can try using a balanced fertilizer that contains all the necessary nutrients. When determining the appropriate dose, be sure to read and follow all instructions provided on the product’s packaging.
Control Pests
If you have found pests such as aphids, mealybugs, or spider mites on the plant, you can try using a safe, organic pest control method or bring the plant to a professional for treatment.
Repot The Plant
If the yellowing leaves are concentrated in one area of the plant and the rest of the plant is healthy, the problem may be that the plant is rootbound (the roots have outgrown the pot). In this case, you can try repotting the plant into a larger pot with fresh soil.
