Monstera leaves curling is one of several indicators that a Monstera may require attention. These plants are renowned for their large, stunning leaves that appear as if composed of multiple segments. When a Monstera is unhappy with its environment or isn’t cared for properly, the first sign often manifests in its leaves. Identifying the cause of Monstera leaf curling may involve a process of elimination and close observation, as numerous factors can contribute to this issue.
Types of Monstera Leaves Curling
Inward Curling Leaves
If your leaves are curling inward or upward, it might indicate underwatering, insufficient humidity, or pest infestation.
Downward Curling Leaves
Several reasons can lead to the downward curling of Monstera leaves. Sometimes, it’s a sign of thermal stress or waterlogging if the leaves lack enough turgor pressure to stay firm. The leaves might appear thin, Monstera leaves drooping, and as if they are wilting.
Crispy, Wrinkled Leaves
Dry or brown edges often signify dehydration or low humidity. Brittle leaves usually indicate this issue.
Why Are Monstera Leaves Curling?
Watering issues, such as under or overwatering, typically trigger Monstera leaves to start curling, especially in Monstera Deliciosa. Maintaining a consistent watering routine can help the leaves unfurl. Other factors like heat, pests, low humidity, and inadequate pot size can also lead to large leaves curling inward. However, it’s normal for Monstera leaves to appear curled during new growth, as they will open up as the plant matures.
Inadequate Watering
Start by checking the soil if you’re trying to understand the reasons behind curled Monstera leaves. Overwatering is a serious issue that can lead to Monstera leaves turning yellow and curling. Overwatered plants may also exhibit wilting. If left unaddressed, overwatering can quickly lead to Monstera root rot. Repot the plant after trimming affected roots to aid in its recovery.
Underwatering can also trigger leaf curling. If you reduce water and the plant becomes dehydrated, it responds by minimizing its leaf surface area to conserve water. Dehydration is the most common cause of curled Monstera leaves, along with other symptoms such as drooping, brittle leaf tips, extremely dry soil, and Monstera leaves turning brown.
Ensure thorough soaking when watering your plant. Continue adding water until it freely drains from the pot’s drainage holes. To prevent future dehydration, regularly check for dry soil and observe the foliage’s appearance every few days.
Monstera’s water requirements vary depending on the season, growth rate, temperature, and light exposure. Therefore, a fixed watering schedule is not recommended.
Inappropriate Humidity
Monstera leaves curling may occur if the humidity is too low. If the plant exhibits brown leaf tips and curling, it’s a clear indication that higher humidity is needed.
Monitor humidity levels with a hygrometer. If the average humidity is above 40%, low air humidity is unlikely to be the cause of Monstera leaves curling. Excess humidity can also be detrimental, especially if Monstera Deliciosa lacks proper air circulation. This can easily lead to fungal issues, causing Monstera leaves to curl or damage.
New Foliage
Don’t panic if newly emerging leaves appear curled; it’s normal for new foliage to be tightly curled, gradually opening as it matures.
Pests
Curling Monstera leaves can be a sign of pest infestations, such as mealybugs, spider mites, or thrips. These pests deplete the plant’s vital nutrients and water content.
Even if you’re watering adequately and the soil looks fine, these pests can deplete the moisture before it reaches the leaves. Inspect the undersides of leaves and stem joints to spot pests on the plant. Another symptom of pest infestation is yellow or spotted rings on the leaves.
Minor infestations can be treated easily with neem oil. However, isolate the plant from other healthy ones first.
Temperature
Indoor plants like Monstera Deliciosa dislike extreme temperatures. Warm drafts or high temperatures can also cause leaves to curl or turn yellow.
Leaf curling is a plant’s response to temperature changes. Move your plant if it’s placed near heaters or in excessively hot outdoor conditions. Leaves lose moisture more rapidly and curl as a protective mechanism to retain moisture. Monstera plants can experience thermal stress during intense summer heat.
Maintain consistent indoor temperatures and position the plant away from air conditioners, heaters, or drafty windows to avoid temperature fluctuations.
Over-fertilization
Beginner plant enthusiasts often over-fertilize their plants. Excess salt buildup harms not only soil microorganisms but also affects the appearance of leaves.
The process of over-fertilization is linked to dehydration and nutrient imbalance as a Monstera struggling with excess nutrients contends with absorbing water and nutrients from the soil, leading to leaf curling.
Conclusion
To maintain healthy Monstera plants, it is essential to focus on proper watering, maintaining suitable humidity, monitoring for pests, and avoiding over-fertilization. Addressing these factors can effectively prevent and remedy issues such as Monstera leaves curling, ensuring that your Monstera remains a vibrant and beautiful addition to your indoor garden.
