Why Is My Peace Lily Turning Yellow? Reasons Explained

Peace lily is a beautifully arranged floral creation that makes it home in various indoor environments all over the globe. For most plant lovers, taking care of a plant is an intimate and heartwarming experience, and even the subtlest signs of destabilized health feel devastating. 

Yellow leaves are one of the most widespread problems associated with the peace lily’s health, though the reasons differ drastically. So, why are my peace lily leaves turning yellow? How do we address this issue and why is an annual “check-up” necessary not only for humans but garden inhabitants, too? 

What Do Peace Lilies Usually Need? 

Throughout the years of indoor gardening, peace lily remains an overly popular solution that captivates plant enthusiasts with its peculiar appearance and plant care requirements that do not seem unreal. Although they are generally considered low-maintenance plants, peace lilies do have specific needs to develop into mature plants and stay healthy further.

Light: A perfect environment for peace lilies presupposes bright, indirect sun, yet low-light conditions may also be more or less suitable. What one should definitely avoid is direct sunlight exposure, for it can cause burns and hinder the plant’s growth in the end.

Watering: Like the majority of houseplants, peace lilies prefer consistently moist soil but they are still sensitive to overwatering. To determine when it is time to water your plant again, check the top few inches of soil, and if it feels dry to the touch, proceed with your regular watering routine.

Humidity: What peace lilies also need is high humidity in the air around. So as to maintain an appropriate humidity level, regularly mist your plants and/or employ a humidifier for quicker results.

Temperature: As a warmth-loving creature, peace lily enjoys temperatures between 65-80°F (18-27°C), so that it can thrive and stay consistent. Sudden fluctuations, though, may pose threats to the plant’s health, for peace lilies are usually too sensitive to any changes.

Soil: Peace lilies ultimately need a well-drained potting mix supported by a balanced, water-soluble fertilizer. It is the soil that takes responsibility for proper water and nutrition absorption, as well as reproduction. 

The Main Reasons Why Peace Lily Goes Yellow

When encountering a problem, one may be thinking: Why does my peace lily have yellow leaves and how do I change it? As soon as the lush green foliage turns yellow, it inevitably becomes a cause for concern. There is no time to panic but put yourself together and take proactive measures according to its cause.

Inconsistent Watering: Water stress is probably the most common issue connected with peace lily care. While some may occasionally overwater a plant and leave it with waterlogged roots, others frequently forget about watering sessions at all but provide peace lilies with water inconsistently. Both conditions mean stress that may result in yellowing leaves.

Improper Sunlight Exposure: What happens when a living being is exposed to direct sunlight without protection to cover with? Indeed, persistent sunlight exposure can scorch the leaves and lead to yellowing. A shady environment, in turn, causes the plant to become weak and pale.

Low Humidity Levels: As we have mentioned before, peace lilies do love humid environments, and when this requirement is missed, they gradually get stressed and turn yellow and brown, too. Hence, it is important to provide your indoor garden with stable conditions with little to no humidity and temperature fluctuations. 

Nutrient Deficiency: When a plant lacks essential nutrients, nitrogen in particular, the leaves of peace lilies surely turn yellow. However, if the soil is being managed and fertilized on a regular basis, such situations are not meant to happen anymore. 

Pest Infestation: When a plant is already stressed, it may be susceptible to pest infestation and other related diseases. Such pests as spider mites, aphids, and mealybugs are the worst enemies of peace lilies that can take advantage of weak conditions and exhaust the plant for good. 

The Age of a Plant: Life is a cycle with a start and an end somewhere far away. Nevertheless, as peace lilies age, it is natural for older leaves to turn yellow and shed, which is not a problem but a normal part of the peace lily’s life. 

How to Troubleshoot Yellow Leaves on the Peace Lily

The first and foremost part is to evaluate if the plant needs pruning or not. When the leaves are severely damaged, it might be beneficial to trim off yellowing leaves to allow your peace lily to focus on new growth rather than reviving what cannot be revived. Then, try to finally answer the question “Why are the leaves of my peace lily turning yellow?” 

As soon as the cause of a problem is found, one should proceed with additional procedures, such as repotting (for waterlogged roots), fertilizing (for nutrient deficiency), prompt pest treatment (for pest infestation), and so on. This is how the issue may be addressed, but what also matters is consistent care, without which restoring your peace lily’s health does not make sense.
