Noticed your ZZ plant’s lush, dark green leaves fading to light green? Don’t worry—this common issue often has a simple fix.
Known for their striking foliage, ZZ plants (Zamioculcas zamiifolia) can lose their vibrant color due to light, water, or nutrient problems.
In this guide, I’ll uncover the top causes of pale ZZ leaves and share easy solutions to restore their deep green glow.
7 Reasons for ZZ Plant Leaves Turning Light Green
New Growth
ZZ plant leaves often start light green when they’re new, darkening as they mature. This is totally normal for fresh growth.
What to Do: Be patient! New leaves typically deepen in color within 2-4 weeks. If they stay pale longer, check for other issues below.
Too Much or Too Little Light
ZZ plants thrive in bright, indirect light. Too much direct sun can bleach their leaves, while too little light hampers chlorophyll production, leaving them faded.
Fix: Move your ZZ to a spot with medium to bright, filtered light—avoid direct sunlight.

Overwatering or Underwatering
Watering issues can throw your ZZ plant off balance, with overwatering being a top culprit for light green leaves. Underwatering, while less common, can also stress the plant. Here’s how to spot and fix both.
Overwatering
Too much water is a frequent reason ZZ plant leaves turn light green. Excess moisture drowns the roots, blocking oxygen and nutrients. Over time, this fades the foliage from rich green to a washed-out shade—sometimes leading to yellowing or browning.
Signs of Overwatering:
- Soft, light green leaves
- Mushy or yellowing foliage
- Soggy soil that stays wet
- Wilting, even in damp conditions
Fix: Stop watering and let the top inch of soil dry out. If roots are black or mushy (a sign of rot), repot in fresh, well-draining soil. Use a pot with drainage holes to prevent water buildup.
Underwatering
Too little water stresses the ZZ plant, though it’s less likely to cause light green leaves directly. It often leads to other signs first.
Signs of Underwatering:
- Dry, crispy leaves
- Soil shrinking from pot edges
- Brown or yellow leaf tips
Fix: Water thoroughly until it drains out the bottom, then wait until the top inch dries before watering again. Aim for every 2-3 weeks, adjusting to your home’s humidity.
Pro Tip: Use a cactus or succulent mix and a pot with drainage for perfect moisture balance.

Lack of Nutrients
ZZ plants need nitrogen, magnesium, and iron to maintain their deep green color. Without them, leaves can turn pale. Nitrogen, for instance, fuels chlorophyll production, keeping foliage vibrant.
Fix: Feed your plant a balanced liquid fertilizer (10-10-10 or 20-20-20) once a month in spring and summer. Avoid over-fertilizing—too much can stress it.
Poor Soil or Root Problems
Heavy, compacted soil blocks nutrient uptake, while root rot (often from overwatering) stops the ZZ plant from staying lush and green.
Fix: Repot with a well-draining mix, like a cactus blend. If roots are black or soft, trim them before repotting.
Wrong Temperature or Humidity
ZZ plants prefer temperatures of 65-75°F (18-24°C) and moderate humidity. Cold drafts or dry air can stress them, fading their leaves.
Fix: Keep your plant away from AC vents, heaters, or drafty windows. Add a humidifier or pebble tray if your home’s air is too dry.
Pests or Disease
Spider mites, aphids, or fungal infections can sap vitality from ZZ leaves, leaving them pale. Pests suck sap, while fungi weaken the plant.
Fix: Wipe leaves with a damp cloth, then treat with neem oil or insecticidal soap. Remove infected leaves to stop the spread.
How to Restore Green ZZ Plant Leaves
- Adjust Light: Place your plant in bright, indirect sunlight.
- Fix Watering: Water only when the top inch of soil is dry.
- Fertilize Smartly: Use a balanced liquid fertilizer monthly in growing season.
- Check Roots: Repot if soil is soggy or roots are rotting.
- Control Pests: Treat with neem oil if you spot bugs or spots.
