Find out how to get rid of yellow leaves on your ZZ plant and get it back to its lush green color!
If you’ve noticed the leaves on your ZZ plant turning a lighter shade of green, you may be wondering what’s causing this change and if it’s something to be concerned about. The good news is, some lightening of leaf color is often natural and not necessarily a sign of a problem. However, in some cases it can indicate issues with care that need to be addressed.
Typical Causes of Light Green ZZ Plant Leaves
There are a few common reasons you may see ZZ plant leaves turning lighter green:
New Growth
It’s very normal for new leaves that are still developing to be lighter in color at first. They will darken over time as they mature. So if it’s only the newest leaves that are light green, this is nothing to worry about. Give them time to darken up to match the older foliage.
Insufficient Light
ZZ plants do best in bright, indirect light. If your plant isn’t getting enough sun, the leaves may start turning lighter green as a result. Try moving it to a spot with more light, but be gradual so you don’t shock or scorch the plant. East or west-facing windows are often ideal.
Overwatering
Too much moisture can lead to root rot and nutrient deficiencies, causing leaves to become pale. Allow the soil to dry out completely between waterings. ZZ plants prefer a relatively dry environment.
Underwatering
On the flip side, not watering enough can also cause leaves to lighten from lack of nutrients and hydration. Stick your finger in the soil to gauge moisture before watering. Water when the top few inches become dry.
Low Humidity
ZZ plants come from tropical areas with naturally high humidity. In drier indoor environments, the leaves may start to pale. Run a humidifier nearby or mist the plant regularly to boost moisture levels.
Temperature Extremes
Exposure to very cold or very hot temps can stress a ZZ plant and affect leaf color. Keep it away from drafty areas as well as heat sources like appliances or heating vents. Ideal temps are 60-75°F.
Nutrient Deficiencies
Lack of nutrients like nitrogen, iron, magnesium, and manganese can all cause leaves to turn light green. Fertilize monthly in spring and summer with a balanced houseplant fertilizer.
Root Damage
If the ZZ’s roots get damaged from repotting, pests, or overwatering, it can affect the plant’s ability to take up nutrients, resulting in lighter leaves. Examine roots and trim any that are black or mushy.
Natural Aging
As ZZ plant stems and rhizomes age over time, the leaves they produce may become lighter naturally. This isn’t harmful. Just remove old stems to encourage new, vibrant growth.
What to Do About Light Green ZZ Leaves
If your ZZ plant’s leaves are turning light green, take these steps to get your plant back to health:
-
Assess care to determine if any cultural factors like light, watering, or temperature need adjustment. Make tweaks as needed.
-
Check the roots and repot in fresh soil if they are damaged or diseased. Trim off affected parts.
-
Move the plant to a spot with more bright, indirect sunlight to encourage darker foliage.
-
Give the plant a thorough soaking anytime the soil is dry 2-3 inches deep. Don’t overwater.
-
Mist the leaves or use a pebble tray to boost humidity around the ZZ plant.
-
Apply a balanced liquid fertilizer monthly during the growing season.
-
Remove any old or dying stems to direct energy to new growth.
-
Be patient! It can take weeks or months for leaves to regain their dark green color.
When to Worry About Light Green ZZ Leaves
In most cases, light green ZZ plant leaves are nothing to be concerned about. However, if the lighter color spreads rapidly or is accompanied by other symptoms like leaf spotting, wilting, or leaf drop, it could indicate a more serious underlying issue that needs treatment.
Yellowing that starts at the base of leaves and spreads outward or affects most of the plant may be a sign of root rot from overwatering. A thorough inspection of the roots is recommended to check for damage.
Sudden widespread lightening of leaves may signal shock from a recent change in conditions like moving the plant or altering watering. Try to determine the trigger and address it.
If lighter leaves correspond with new limp or curled growth, it can point to a nutrient deficiency. Fertilizing more often should help.
Watch for pests like spider mites that can suck nutrients from leaves, causing lightening. Treat with insecticidal soap spray if spotted.
With proper care, ZZ plants are pretty hardy and tolerant of occasional light green leaves. But if the condition persists or worsens despite your efforts, consulting a horticulturalist may be worthwhile.
Caring For Your ZZ Plant
Here are some tips to keep your ZZ plant looking its best:
-
Place in bright, indirect sunlight. East or west-facing windows are ideal.
-
Water thoroughly only when the top few inches of soil are dry. Don’t overwater.
-
Mist leaves or use a pebble tray for humidity. Aim for 40-60%.
-
Repot every 2-3 years in a container one size larger with fast-draining soil.
-
Fertilize monthly from spring through summer with a balanced liquid fertilizer.
-
Prune old stems and leaves at the base to encourage new growth.
-
Keep away from drafts, heat sources, and cold windows. Ideal temperature is 60-75°F.
-
Watch for pests like mealybugs and spider mites and treat promptly.
-
Allow light green new growth time to mature and darken. It’s usually normal.
With proper care and favorable conditions, ZZ plants can grow for decades and their lush green leaves will remain a vibrant, healthy color. Pay attention for any worrying changes, but otherwise sit back and enjoy this easy-care houseplant.
Proper Watering Techniques
Lets dive into the art of hydration. Overwatering is a common mistake, often leading to yellowing leaves. The ZZ Plant stores water in its rhizomes and likes it dry. It’s kind of like a camel. So, how do you know when to water?.
Wait until the top 3 inches of soil feel dry. If youre unsure, use a water meter. When its time to water, moisten the entire root zone. Water should be exiting the drain hole when youve given enough. Remember, your ZZ Plant isnt a fan of overhead showers. Deliver water slowly to the base of the plant.
Avoid letting your pot sit in standing water. Its like leaving your feet in a puddle – not comfortable, right?.
Next up, lets talk plant food. Nutrient deficiencies can also cause yellowing leaves. Your ZZ Plant needs a balanced diet, just like you do.
Use a low-nitrogen fertilizer every three weeks during the growing period. But hold off in the fall and winter when the plant goes dormant. Its like the ZZ Plants version of intermittent fasting.
If youve already got the basics down, consider incorporating a plant multivitamin into your care routine. These mixtures have a lot of zinc, iron, and boron, which are all important nutrients for plants to use light and keep growing strong.
Finally, lets tackle the creepy crawlies. Pests like aphids and mealybugs can cause yellowing leaves.
Regularly inspect your ZZ Plant for signs of infestation. It’s easier to get rid of pests before they do a lot of damage to your plant.
Neem oil is a good way to ward off these uninvited guests. You can also wipe them away with a mixture of water and a few drops of dish detergent.
Remember, a clean plant is a happy plant. Regularly wipe away dust from your ZZ Plants leaves to ensure optimal photosynthesis. But avoid commercial leaf shine products that can suffocate the leaves.
Preventing yellowing leaves is all about understanding your ZZ Plants needs and acting proactively. You can keep your ZZ Plant looking green and glossy by giving it the right amount of water, food, and care, and keeping pests away.

Adjusting Watering Practices
If you water your plants too much, the roots will drown, but if you water them too little, the roots will dry out. Both scenarios can lead to those dreaded yellow leaves.
Overwatering is a common culprit. If your ZZ plants leaves are yellow, limp, and curling downwards, its time to play detective. Check the soil and the roots. If the roots are brown and mushy, your plants been taking too many water shots. Healthy roots, on the other hand, are firm and white.
Underwatering can also cause yellowing. If the leaves are dry, yellow, and crispy around the edges and the soil is bone dry, your ZZ plant may need more water than a camel in the desert.
