Aglaonema, commonly known as the Chinese Evergreen, is a popular houseplant admired for its lush foliage and low-maintenance nature.

However, one common issue many Aglaonema plant owners face is browning leaf tips. This can be frustrating, especially when you’re unsure of the cause.

In this article, we’ll explore the 10 best reasons why the tips of your Aglaonema are turning brown and provide actionable solutions to restore your plant’s health.

Why Are The Tips Of My Aglaonema Turning Brown?

1. Low Humidity Levels

Aglaonema thrives in environments with moderate to high humidity. When the air is too dry, the leaf tips can turn brown as the plant struggles to retain moisture. This is especially common during winter when indoor heating reduces humidity levels.

To combat this, consider using a humidifier near your plant or placing a tray of water nearby. Misting the leaves occasionally can also help increase humidity. However, avoid over-misting, as it can lead to fungal issues.

If low humidity is the issue, you’ll notice browning tips alongside dry, crispy edges. Increasing humidity will prevent further damage and keep your Aglaonema looking vibrant.

2. Overwatering

Overwatering is a common cause of browning tips in Aglaonema. When the roots sit in waterlogged soil, they can’t absorb oxygen properly, leading to stress and browning. This issue is often accompanied by yellowing leaves.

To prevent overwatering, ensure your plant is in well-draining soil and a pot with drainage holes. Allow the top inch of soil to dry out before watering again. Adjust your watering schedule based on the season and humidity levels.

If overwatering is the culprit, you may also notice root rot. Repotting the plant in fresh soil and trimming damaged roots can help revive it. Proper watering practices will prevent future browning.

3. Underwatering

While overwatering is a common issue, underwatering can also cause browning tips. When the plant doesn’t receive enough water, the leaves lose moisture, leading to dry, brown edges. This is often seen in plants placed in bright, dry areas.

To fix this, establish a consistent watering schedule. Check the soil moisture regularly and water when the top inch feels dry. Ensure the water reaches the root zone without leaving the soil soggy.

If underwatering is the issue, you’ll notice the browning tips alongside wilting leaves. Proper hydration will restore your Aglaonema’s health and prevent further damage.

4. Exposure to Direct Sunlight

Aglaonema prefers bright, indirect light and can suffer when exposed to direct sunlight. The intense rays can scorch the leaves, causing the tips to turn brown. This is especially common in south-facing windows.

To protect your plant, move it to a spot with filtered light or use sheer curtains to diffuse the sunlight. Rotate the plant occasionally to ensure even light exposure. Avoid placing it near windows with intense afternoon sun.

If direct sunlight is the issue, you’ll notice browning tips alongside faded or scorched leaves. Adjusting the light conditions will help your Aglaonema thrive.

5. Fluoride in Water

Tap water often contains fluoride, which can accumulate in the soil and cause browning tips in Aglaonema. This is more common in areas with high fluoride levels in the water supply.

To avoid this, use filtered or distilled water for your plant. Alternatively, let tap water sit overnight to allow some chemicals to evaporate before using it. Flushing the soil occasionally can also help remove excess fluoride.

If fluoride is the issue, you’ll notice browning tips alongside stunted growth. Switching to filtered water will prevent further damage and promote healthy growth.

6. Nutrient Deficiency

A lack of essential nutrients, particularly nitrogen, can cause browning tips in Aglaonema. Nutrient deficiency often occurs when the plant has been in the same soil for too long or isn’t fertilized regularly.

To address this, use a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. Ensure the fertilizer is diluted to half strength to avoid over-fertilization. Repotting the plant in fresh soil can also replenish nutrients.

If nutrient deficiency is the issue, you’ll notice browning tips alongside pale or yellowing leaves. Proper fertilization will restore your plant’s vitality.

7. Temperature Stress

Aglaonema prefers temperatures between 65-80°F (18-27°C). Exposure to extreme temperatures, whether hot or cold, can cause browning tips. Drafts from windows, doors, or air conditioners can also stress the plant.

To prevent this, keep your plant in a stable environment away from drafts and sudden temperature changes. Avoid placing it near heating vents or air conditioners. Maintain consistent temperatures for optimal growth.

If temperature stress is the issue, you’ll notice browning tips alongside curling or drooping leaves. Adjusting the environment will help your Aglaonema recover.

8. Pest Infestation

Pests like spider mites, mealybugs, and aphids can cause browning tips by feeding on the plant’s sap. These pests often thrive in dry, dusty conditions and can quickly spread to other plants.

To eliminate pests, wipe the leaves with a damp cloth or use insecticidal soap. Regularly inspect your plant for signs of infestation and isolate affected plants to prevent spreading. Maintaining proper humidity levels can also deter pests.

If pests are the issue, you’ll notice browning tips alongside webbing or sticky residue. Prompt treatment will save your Aglaonema from further damage.

9. Chemical Buildup in Soil

Over time, salts and chemicals from fertilizers and water can accumulate in the soil, causing browning tips. This buildup can damage the roots and prevent proper nutrient absorption.

To fix this, flush the soil with water every few months to remove excess salts. Repotting the plant in fresh soil can also help. Use distilled or filtered water to prevent further buildup.

If chemical buildup is the issue, you’ll notice browning tips alongside crusty soil surfaces. Flushing the soil will restore its health and prevent further damage.

10. Natural Aging

As Aglaonema ages, older leaves may naturally develop browning tips before falling off. This is a normal part of the plant’s growth cycle and not a cause for concern.

To maintain your plant’s appearance, trim the brown tips with clean scissors. Focus on providing optimal care to support new growth. Regularly remove dead or yellowing leaves to keep the plant healthy.

If natural aging is the issue, you’ll notice browning tips only on older leaves. Proper care will ensure your Aglaonema continues to thrive.

Why are the tips of my Aglaonema turning brown FAQs

1. Can I cut off the brown tips of my Aglaonema?
Yes, trimming brown tips with clean scissors can improve the plant’s appearance. Ensure you don’t cut into healthy tissue.

2. How often should I fertilize my Aglaonema?
Fertilize every 4-6 weeks during the growing season with a balanced, water-soluble fertilizer diluted to half strength.

3. Is Aglaonema safe for pets?
No, Aglaonema is toxic to pets if ingested. Keep it out of reach of cats and dogs.
