Monstera Leaves Curling

Why Are My Monstera Leaves Curling | How to Fix It

Here's a comprehensive guide to solving monstera leaf curling problems

Monstera deliciosa, commonly known as the Swiss cheese plant, graces homes with its lush, tropical presence. While these plants are generally hardy, Monstera leaf curling can be a perplexing issue for many plant enthusiasts. In this extensive guide, we’ll delve deeper into the causes and solutions for Monstera leaf curling, ensuring your beloved plant thrives and flourishes.

Understanding Monstera Leaf Curling

Monstera plants, renowned for their glossy, dark green leaves and unique perforations, may exhibit leaf curling due to various environmental factors. Recognizing the symptoms and addressing them promptly is essential for maintaining the health of your Monstera.

Common Causes of Monstera Leaf Curling

Curling Upwards: Dehydration

When Monstera leaves exhibit the distinctive curling upwards, it’s often a sign of dehydration. The plant is signaling a desperate need for more water, attempting to retain moisture and limit transpiration. To remedy this issue, ensure a thorough watering until water drains from the container, repeating the process until the leaves begin to uncurl. Maintaining consistent soil moisture is crucial, so monitor the top 2 inches of the soil and water when it feels dry. By addressing dehydration promptly, you’ll revive your Monstera’s vibrant appearance and promote overall health.

Curling Downwards: Saturated Soil

When your Monstera leaves start curling downwards, it’s a clear indication of saturated soil, often stemming from poor drainage or over-watering. The plant’s roots are struggling in waterlogged conditions, leading to a range of symptoms such as downward-curling leaves, stunted growth, and pale water-soaked leaves. To remedy this, cease watering immediately and allow the soil to dry before resuming a more controlled watering routine. If oversaturation persists, consider transplanting your Monstera into a well-draining soil mixture to provide the optimal conditions for root health. By addressing the issue of saturated soil, you’ll rejuvenate your Monstera and encourage vigorous, thriving growth.

Curling with Brown Edges: Low Humidity

The phenomenon of Monstera leaves curling with brown edges is often attributed to low humidity levels in its environment. These tropical plants thrive in humid conditions, and when exposed to extended periods below 40% humidity, the leaves respond with curling and browning along the edges, particularly near the tips. To counteract this issue, consider increasing the humidity around your Monstera. Grouping houseplants together, placing moistened gravel in the catch tray, or misting the plant every 2-3 days are effective strategies. Alternatively, adding a humidifier to the room can provide a consistent humidity boost. By addressing the low humidity factor, you’ll promote healthier foliage and prevent the unsightly curling with brown edges in your Monstera plant.

Curling, Yellowing, and Browning: Salt Stress

When your Monstera leaves display a combination of curling, yellowing, and browning, salt stress is often the culprit. This occurs due to exposure to unfiltered tap water or overfertilization, leading to an excess of salts in the soil. The result is a cascade of symptoms, including discoloration, leaf curling, stunted growth, and premature leaf senescence. To address salt stress, flush the soil with filtered water until drainage occurs, repeating the process over the next 48 hours. If improvement isn’t observed within 4-5 days, consider transplanting your Monstera into new soil. Opt for rainwater or filtered water in your watering routine to prevent the gradual buildup of harmful salts. Additionally, incorporating calcium-rich fertilizers during times of sodium stress can provide vital protection to your Monstera, sustaining potassium transport within the plant and suppressing salt importation. Consider these measures to ensure a thriving, salt-stress-free Monstera.

Curling, Wilting, and Stunted Growth: Root Death

When you notice your Monstera displaying signs of curling, wilting, and stunted growth, it’s often indicative of root death caused by becoming root-bound. As the roots struggle within confined space, the plant exhibits symptoms such as curled and yellow leaves, along with inhibited growth. To address this issue, consider transplanting your Monstera into a container that is 2-3 inches larger than its current one. During the transplant, avoid removing all the soil from the root ball, and apply mycorrhizal inoculant on exposed roots to facilitate quick acclimation. Younger plants may benefit from annual transplanting, while larger Monstera plants typically require repotting every 2-3 years. By ensuring ample room for root expansion, you’ll rejuvenate your Monstera, promoting healthier foliage and robust growth.

Curled, Wilted Leaves, and Bent Stems: Lack of Support

When your Monstera leaves appear curled, wilted, and accompanied by bent stems, it’s a clear indication that the plant lacks proper support. Monstera plant can be prone to bending or arching stems, especially as they grow taller. To address this issue, follow the advice from the University of Hawaii and train your Monstera to grow on moss totem poles, trellises, or other supports. Providing the necessary support helps maintain the plant’s structure, preventing stems from bending under their weight. By incorporating these supportive measures, you’ll encourage your Monstera to grow healthily, showcasing its distinctive leaves and maintaining an attractive, upright appearance.

Curled and Yellow: Excessive Light

If you observe your Monstera leaves curling and turning yellow, it’s a clear signal of excessive light exposure. Monstera plants thrive in bright but indirect sunlight, and when subjected to too much direct sunlight, their leaves can suffer. To remedy this, consider adjusting the plant’s placement by using sheer curtains to diffuse light or relocating it at least 9 feet away from uncovered windows or main doors. Moving your Monstera to a low-light area is not advisable, as it may result in slower growth and erratic stretching. Regularly rotating the plant can also help limit stretching, ensuring a balanced light exposure. By finding the right balance of light, you’ll restore your Monstera’s vibrant green hue and prevent further leaf curling and yellowing.

Curled and Purplish: Phosphorus Deficiency

When your Monstera leaves display a distinctive curling with a purplish tint, it’s often a sign of phosphorus deficiency. This essential nutrient plays a crucial role in various physiological processes within the plant. Monstera plants experiencing phosphorus deficiency may show distorted leaves that drop prematurely, with older leaves developing a purplish hue underneath and younger leaves exhibiting purplish veins. To address this issue, apply a soluble fertilizer with an N-P-K ratio of 1–0.5–1. This balanced ratio ensures the plant receives the necessary nutrients without risking burn, salt buildup, or root shock. By addressing the phosphorus deficiency, you’ll promote healthy leaf development and restore your Monstera’s vibrant appearance.

Further Tips for Monstera Care

Maintaining a healthy Monstera involves more than just addressing leaf curling. Here are additional tips to ensure your plant thrives:

  • Proper Feeding: During the growing season, use a balanced fertilizer to provide essential nutrients. Follow recommended application rates for optimal plant health.
  • Regular Pruning: Trim yellow or damaged leaves to encourage new growth and maintain the plant’s aesthetic appeal. Pruning also helps redirect energy to healthy foliage.
  • Optimal Temperature: Monstera plants flourish in temperatures between 65-75°F (18-24°C). Avoid exposing them to extreme temperature fluctuations.
  • Pest Prevention: Monitor your Monstera for common pests like spider mites and scale insects. Regularly inspect the leaves and take prompt action if pests are detected.
  • Soil Health: Ensure your Monstera is potted in well-draining soil. Consider a mix with components like coconut coir, perlite, and worm castings for optimal aeration and nutrient retention.
  • Support for Growth: As your Monstera matures, provide support for its climbing nature. Moss totem poles, trellises, or other supports can help facilitate healthy growth.
  • Light Management: Maintain a balance of bright but indirect sunlight. If your Monstera exhibits leaf issues due to light exposure, consider adjusting its placement or using sheer curtains to filter sunlight.
