ZZ Plant’s Leaves Curling: Causes And Solutions
I am sure even if you are a beginner gardener, you will want your plant’s leaves to look beautiful and amazing.
But why do my ZZ plant’s leaves curl up?
There are several reasons why the ZZ plant’s leaves curl up. Luckily for you, I have made a complete list to help you with the questions that you have in your mind right now.
So, let us first start with the sunlight issue. Keep reading!
1. Does sunlight cause the ZZ plant’s leaves to curl?
Yes, too much sunlight is the main cause of curled ZZ plant leaves. This is probably the issue if the leaves have dark burn patches and are curled. If you place your ZZ plant outside for too long or on the window sill for long hours, especially during summers and you forget to bring it inside, the leaves of the ZZ plant curl up and can even change color or have a sunburn. So, lets now explore some steps below on how you can fix this issue:
- Medium, indirect light is preferred for ZZ plants. Long-term exposure to direct sunlight causes the leaves to curl as they attempt to flee the source of light.
- Relocate the plant away from the window and into a more shaded area. If moving the plant is not an option, cover the window with a sheer drape.
- Windows that face south, in particular, let in a lot of light. ZZ plants do not benefit from this sunshine like other plants like succulents may. The ideal windows are those that face east or west since they get enough light without being too intense.
Note to remember: Even when the plant is placed in the shade, brown sunburn patches on the foliage do not go away. Trim the leaves to get rid of burn stains.
2. ZZ plant leaves curling because of lack of water
Although ZZ plants are renowned for their ability to withstand drought, they can nevertheless become waterlogged. Your ZZ plant needs a good drink if you see curled leaves and dried, brown tips. If the soil is extremely dry, check it with your finger and water your plant. I have given some tips below on how you can fix this issue!
- Water the ZZ plants every two weeks in the summer and every three to four weeks in the winter. According to the unique environment of your facility, modify this timetable as necessary (humidity, temperature, and light received).
- More water is needed by plants in hotter, brighter environments than by plants in chilly, dark environments. It is recommended to water at the plant’s base until water begins to drain from the drainage hole.
- After that, let the soil dry before watering it again. The soil should not be misted in between waterings. ZZ plants prefer periods of dryness interspersed with periods of saturation.
3. ZZ plant leaves curling from overwatering
On the other hand, over-watering might cause leaves to curl. Overwatering can cause root rot, which is indicated by brown stems and yellow, mushy, and curled leaves. ZZ plants can endure drought, but they cannot stand too much wetness around their roots.
Reduce the frequency of watering and prune your plant if root rot is the problem. Before watering again, wait as long as a month to let the soil dry out. So that the soil dries up more quickly, keep the plant in a warm environment with medium-intensity indirect light. Let us now check out how you can prevent root rot in ZZ plants which I have discussed below!
How can you prevent root rot in ZZ plants?
Keep in mind that overwatering is the main reason ZZ plants die. As it is considerably simpler to fix, it is better to take care on the side of underwatering. Simply follow the steps given below to prevent root rot from overwatering the ZZ plants!
- Before watering again, always wait for the top inch of soil to dry off.
- A basic terracotta pot with a drainage hole is the ideal item to use. This enables extra water after watering to flow away. Pour out any water that accumulated in the saucer as well to prevent the plant from spending too much time there.
- Add perlite or gravel to the soil to improve drainage. As a result, the mixture becomes porous, allowing the roots to breathe.
4. ZZ plant leaves curling as a result of the cold
ZZ plants, which are native to tropical regions, prefer warmer temperatures between 65 and 80 °F (18 and 27 °C). The leaves could curl from the cold if they are kept in temperatures below 50 °F.
To keep your ZZ plant warm, keep it away from AC vents, fans, and draughty windows. Consider placing a humidifier or air purifier near your ZZ plant if the air is really dry and the tips of the plant appear crispy.
5. Pests can make the ZZ plant’s leaves curl
Many pests, including aphids, mealy bugs, and thrips, can alter the morphology of leaves. These insects alter the look of the plant by sucking its sap.
Examine the plant thoroughly for any indications of insects, paying close attention in particular to the underside of the leaves. If pests are found, relocate the ZZ plant far from any nearby plants to prevent the infestation from spreading. Use insecticidal soap, diluted neem oil, or rubbing alcohol to mist the plant. Repeat until the infestation is eliminated every three to four days (it may take several weeks).
6. ZZ plant leaves curled because of root entanglement
Rhizomes, which are plant-specific bulbs that store water and nutrients, are the source of growth for ZZ plants. The leaves may curl if the rhizomes become rootbound and unable to expand.
Every few years, repot ZZ plants to allow them to expand, especially if you see roots poking through the soil. Select a pot with a diameter that is one to two inches larger than the existing one (do not choose a pot that is too large, because the excess soil retains water and promotes root rot). Pick a soil for indoor plants that drains well and add perlite to improve drainage.
Prevention Tips: Prune a Curly ZZ plant leaf!

It is preferable to cut the stems close to the plant’s base as opposed to specific leaves or sections of the stem. Even plants don’t appreciate choppy hairstyles! Follow the steps I have given below before pruning the curled leaves of the ZZ plant!
