People love the Monstera Deliciosa. It’s also called the Swiss Cheese Plant. They love it for its vibrant, tropical leaves. This makes it a top pick for indoor gardeners. Yet, a frequent challenge is the curling of its leaves. This guide examines why this happens and provides thorough solutions.
What Causes Curling Leaves in Your Monstera Deliciosa?
Under the right conditions, your Monstera Deliciosa should thrive. The conditions are steady warmth, high humidity, indirect sunlight, and light fertilization. They should be from spring to autumn. It will grow and reach upwards when given support.
But, if you’ve spotted curling leaves on your plant, the cause is usually one of the nine reasons below. Let’s dive into these causes and learn how to fix them.
1. Insufficient Watering
One of the main reasons for curling leaves in Monstera Deliciosa is not enough watering. If the plant is not watered enough or if watering is not timely, the leaves may begin to curl. To fix this, first check the soil’s moisture by feeling it below the surface. Check to be sure it hasn’t dried out.
Solution:
Water the plant , ensuring that the water reaches deep into the soil. If the soil has begun to crack, loosen it first. Then, water it to ensure it absorbs the water well. Consider watering the plant many times to saturate the soil. A few days after watering, check the soil’s moisture. Also, see if the leaves have started to uncurl. Remember to check the soil to prevent it from drying out.
2. Low Air Humidity
Most tropical foliage plants, including Monstera Deliciosa, prefer a high humidity environment. Dry air slows growth and makes the plant’s leaves curl and turn brown. To thrive, they need conditions like a tropical rainforest.
Solution:
Raise the humidity around your Monstera by misting the leaves. Misting also helps to clean them. Also, a small humidifier near the plant can raise the nearby humidity. Placing your Monstera with other tropical plants can create a “rainforest effect.” They do this through their transpiration, which keeps local humidity high. Also, put a tray of pebbles and water under the pot. This can help raise humidity as the water evaporates.
3. Overwatering
An overwatered Monstera can be due to two main reasons. The soil may not drain well. Or, the owner waters too often.
Overwatering often causes yellowing and wilting. It can also cause leaf curling.
Solution:
If you notice the soil stays wet, drain excess water. Then, move your Monstera to a better-ventilated area. Elevate the pot to dry it more . Provide some gentle, diffused light to help.
In severe cases, you may need to remove the top layer of soil. This is to check for black, rotten roots, which need immediate attention.
If you find root rot, take the plant out of its pot. Cut away the rotten roots. Soak the healthy roots in a fungicide for half an hour. Then, replant in fresh, well-draining soil.
4. Sudden Temperature Changes
Quick temperature shifts can be from a heatwave or a cold draft. They can cause Monstera leaves to curl. Don’t put your plant in spots that are too hot or too cold. This includes near heating vents or air conditioning units. Big temperature swings can dry out the plant and make its leaves curl.
Solution:
Keep the plant in a place with stable temperatures. This will prevent rapid changes. Avoid placing your Monstera in spots where temperatures exceed 95°F (35°C) or drop below 50°F (10°C). In colder conditions, below 41°F (5°C), there’s a risk of frost damage. Ensuring good air circulation can also help mitigate extreme temperature effects.
5. Using Chlorinated Tap Water Long-Term
In some areas, tap water contains chloramines. Chloramines can kill helpful soil microbes. Watering your Monstera Deliciosa with chlorinated tap water may make the leaves curl. It can also make their edges crispy.
Solution:
Let tap water sit in an open container for a day or two before using it; this allows the chloramines to evaporate. Adding beneficial microbial fertilizers to the soil can also mitigate the negative effects. Of course, using rainwater for watering is the best option if available.
6. Pest Infestations
Indoor Monstera Deliciosa plants can get pests. This is especially true in dry air, which can lead to more spider mites. These pests make the leaves rough. They cause yellow spots on the undersides by sucking the plant’s juices. This leads to yellow, dried-out leaves and curling.
Spider mites are very small and hard to detect. They are often overlooked until they cause significant damage. It’s crucial to inspect the undersides of the leaves for tiny spots or a rough texture.
Solution:
Rinse the affected leaves with clean water as a first step. If you prefer not to use chemicals indoors, you can apply soap water, neem oil, or rubbing alcohol as a treatment.
For outdoor plants, direct application of insecticides can be more straightforward. For spider mites, use products like sulfur or miticides. They can be effective. Apply them every three days for 2-3 times.
7. New Leaf Curling
There’s no need to worry if you notice new leaves on your Monstera Deliciosa curling as they emerge. It’s natural for new leaves to start off curled and then unfold as they grow. This is a healthy sign of growth in Monstera plants.
8. Pot Too Small
If you keep a large Monstera in a pot that is too small, the soil will dry out. This can cause the leaves to curl due to lack of moisture.
If you see the roots of your Monstera have filled the pot. Some roots are even starting to emerge from the holes. This indicates that the plant is overcrowded and requires repotting. The best time to repot is in the spring, when temperatures are above 64°F (18°C).
9. Over-fertilization
Over-fertilizing your Monstera Deliciosa can lead to too many nutrients in the soil. This can affect its pH and harm the plant’s roots. This imbalance can hinder the plant’s water absorption. It causes leaf curling.
Solution:
If you’ve used too much fertilizer and notice the leaves curling, flush the soil with clean water. Do this to wash away excess nutrients.
If you suspect root damage in severe cases, you must remove the plant from its soil. Trim away any damaged roots, rinse the rest with water, and replant in fresh, well-draining soil.
Conclusion
To fix Monstera Deliciosa leaves curling, grasp what your plant needs. Then, react to its environment and care needs. Proper watering and humidity, avoiding overwatering, and fertilizing are key. Also, guard against sudden temperature shifts. They keep your Monstera Deliciosa healthy and attractive. Following the guide’s advice will help you fix leaf curling. This will let you enjoy your Swiss Cheese Plant’s tropical charm for many years.
