Monstera Leaves Turning Yellow: 17 Expert Tips

If you’re a proud owner of a Monstera plant, you’re probably no stranger to its lush green leaves and striking appearance. The Monstera deliciosa, often recognized as the Swiss cheese plant, is a favored selection among indoor plant enthusiasts owing to its distinctive foliage and relatively straightforward maintenance requirements. You can easily propagate this plant in 3 ways. However, if you’ve noticed your Monstera leaves turning yellow, it can cause concern. The yellowing of leaves can indicate a range of problems impacting the overall well-being of your plant. In this article, we will explore the common reasons why your Monstera might be turning yellow and offer solutions to help bring your plant back to its vibrant green glory. Let’s dive into Monstera care.

1. Natural Aging Process: Leaves Aging Gracefully

Before jumping to conclusions and assuming something is seriously wrong with your Monstera, it’s essential to understand that yellowing leaves can be a natural part of the plant’s growth and aging process. Like all living organisms, Monstera plants have a finite lifespan for each leaf. As older leaves age, they will naturally turn yellow and eventually brown before dying off. This is entirely normal, and there’s no need to worry.

Spotting the Difference: Natural Aging vs. Troubled Health

To distinguish between natural leaf aging and a problem with your plant’s health, examine the location of the yellow leaves. If the older, lower leaves are yellowing while new growth remains green, it’s likely just a part of the Monstera’s natural cycle.

2. Why Monstera leaves turning yellow: Overwatering

One of the most common causes of Monstera leaves turning yellow is overwatering. Monstera plants are tropical in origin and prefer consistently moist but well-draining soil. If the soil becomes waterlogged and lacks proper drainage, the roots can suffocate, leading to root rot. As a result, the plant’s ability to take up nutrients and water becomes impaired, causing yellowing leaves and other symptoms of stress.

Solution: Nurturing with Care

• Adjust Your Watering Routine: Make sure the top one to two inches of the soil dries out before giving your plant a drink. Verify the moisture level by inserting your finger into the soil before the next watering. It’s relatively safer to go underwater than to overwater your Monstera.
• Use Well-Draining Soil: Re-pot your Monstera in a well-draining potting mix to ensure excess water can escape quickly and reduce the soil moisture.
• Choose the Right Pot: Make sure that your pot includes drainage holes to avoid the accumulation of excess water at the base.
• Empty Saucers: Don’t let your Monstera sit in a saucer filled with excess water. Empty the saucer after watering to avoid root rot.

3. Why Monstera leaves turning yellow: Underwatering

While overwatering is a common issue, underwatering can also cause your Monstera’s leaves to turn yellow. Like many other tropical plants, insufficient water supply can induce stress, resulting in the wilting and discoloration of its leaves.

Identifying the signs of underwatering is the first step in addressing this issue. When your Monstera doesn’t receive sufficient water, its leaves may start to droop, become limp, or curl inward. Additionally, you might observe leaf edges turning brown, crispy, or completely yellow leaves. Over time, the plant may shed leaves, especially the older ones at the bottom. These visual cues can alert you that your Monstera requires more moisture to thrive.

Solution: Hydration is Key

• Establish a Consistent Watering Schedule: Check the moisture level regularly and water your Monstera when the top inch or so of the soil is dry. The frequency may vary depending on your home’s humidity and environmental conditions.
