The ZZ plant (Zanzibar Gem) is a popular houseplant due to its ability to tolerate low light conditions and its ease of care.
However, when one notices their ZZ plant’s leaves curling, it can be a sign that something is wrong.
In this article, we’ll discuss some of the potential causes of curled or drooping leaves on your ZZ plant, as well as how you can go about fixing them.
What Causes of My ZZ Plant Leaves Curling?
There can be several causes for the curling of your ZZ plant’s (Zamioculcas zamiifolia) leaves. These include:
Overwatering
Like most houseplants, overwatering is one of the main culprits behind leaf curl on your ZZ plant. The best way to avoid this problem is by only giving your ZZ plant enough water when the top inch or two of the soil feels dry.
Underwatering
On the other hand, underwatering can also cause leaves to curl. If you think this may be the issue for your plant, try increasing the water slightly and check back in a few days to see if there has been any improvement.
Sunburn
Too much direct sunlight can cause leaf curling and burn on your ZZ plant, so it’s always best to avoid any direct sunlight exposure if possible.
If you do have sunlight coming into the area where your ZZ plant resides, try filtering it with sheer curtains or blinds to reduce its intensity before it reaches your plant.

Pests
Another potential cause for curled leaves on your ZZ plant could be pests such as mealybugs or mites that are feeding off its sap and causing damage.
If this is the case then you will need to treat your plant with an appropriate insecticide as soon as possible in order to get rid of them before they spread further throughout the entire potting medium and foliage.
How Can I Fix My Curled Leaves?
Once you have identified what might be causing leaf curl on your ZZ Plant, here are some tips on how you can go about fixing them:
- Make sure that you are watering at regular intervals when necessary (see above). You should also test out different irrigation techniques such as using less frequent but deeper watering sessions in order to find out what works best for your particular species of houseplant.
- Move your plants away from direct sunlight or use sheer window screens/blinds in order to reduce any burning caused by excessive sunlight exposure.
- Check for signs of pests such as yellow staining or sticky deposits on the surface of leaves which could indicate a pest infestation that needs treating immediately with an appropriate insecticide or miticide product (see below).
- Prune away any browned/dead leaves from time to time in order to encourage dense growth and vigorous health for the rest of the foliage remaining intact on the stem/branches of your specimen(s).

Should I Cut Already Curled leaves?
There is no definitive answer to this question, as it will depend on the cause of the curled leaves. For example, if your ZZ plant’s leaves are curling due to under or overwatering, then you should avoid cutting away already curled leaves, as doing so would remove any source of moisture for the rest of the leaves.
On the other hand, if your plant is showing signs of pest or disease damage, then you may need to cut away leaves that appear to be affected in order to limit the further spread and help restore health to the rest of the foliage.
So in general, it’s best to consult with a local garden center or horticultural professional for specific advice on treating your particular ZZ plant’s curled leaves.
Conclusion
Leaf curl is often a sign that something isn’t quite right with a houseplant – whether it’s too little water being provided or pests taking hold which need treating immediately – but thankfully most issues can easily be fixed given enough time and attention!
By following some simple tips outlined above such as providing regular irrigation when necessary, shielding direct sunlight exposure where possible, monitoring for pests regularly, and pruning away dead foliage from time-to-time; to then hopefully, these issues won’t arise again anytime soon!
