Calla Lily Leaves Turning Yellow: Understanding the Causes

Before we can effectively combat the issue of calla lily leaves turning yellow, it’s crucial to understand the root causes behind it.

This section delves deep into the possible reasons for this problem, equipping you with the knowledge to identify what might affect your plants.

From natural aging to improper care routines, we’re about to unravel the mysteries behind those discolored leaves. Let’s commence this enlightening journey.

Understanding the Causes of Yellowing Leaves

Natural Aging Process

Let’s start with something perfectly normal – the natural aging process. Like us, plants age, and it’s part of their lifecycle to occasionally shed older leaves to make way for new growth.

These aged leaves may turn yellow before falling off, which, if isolated, is no cause for concern.

However, if your Calla Lily is losing an excessive number of leaves or if the younger ones are also turning yellow, it’s time to look at other potential factors.

Incorrect Watering Schedule

Watering, simple as it sounds, can be a bit tricky. Calla Lilies are particularly sensitive to their watering schedules, and overwatering and underwatering can lead to their leaves turning yellow.

Signs of Overwatering

Overwatering is one of the most common mistakes made by plant owners. It’s crucial to understand that while Calla Lilies love moisture, too much water can be detrimental. The plant’s roots may become waterlogged and oxygen-deprived when overwatered, leading to root rot.

This causes the plant to stress, and it shows in its leaves. Yellowing, wilting leaves, often accompanied by a rotting smell or mold, are telltale signs that your plant might be getting too much water.

Signs of Underwatering

On the flip side, underwatering can be just as damaging. Calla Lilies that don’t receive enough water may also show yellowing leaves, usually starting at the tips and edges. These leaves may also appear dry, brittle, and curled.

If you notice these signs and the dry soil, your plant might be pleading for more water.Remember, achieving the right watering balance is key. Not too much, not too little, but just right – this is the golden rule.

Soil Issues

Just like humans need a comfortable living environment, Calla Lilies, too, require the right soil conditions for optimal growth.

Various soil-related factors, such as poor drainage, nutrient deficiencies, and imbalanced pH levels, can be the cause of calla Lily leaves turning yellow.

Soil Issues

Poor Drainage

Poorly draining soil is a common culprit behind many plant issues. When water cannot escape from the soil, it creates a waterlogged environment that suffocates the plant’s roots, similar to the overwatering scenario we discussed earlier.

This lack of oxygen leads to root rot and yellowing leaves. If the soil remains waterlogged for extended periods after watering, it might be a sign that you need to improve its drainage.

Nutrient Deficiencies

Your Calla Lily relies on the soil for essential nutrients to fuel its growth. If the soil lacks these nutrients, the plant may show signs of distress, including yellowing leaves.

In particular, a deficiency of nitrogen – a critical nutrient for plants – can cause leaves to turn yellow because it’s vital for their green coloration (chlorophyll).

Imbalanced pH Levels

Imbalances in the soil’s pH can drastically affect your Calla Lily’s health. It’s essential to know that pH measures how acidic or alkaline a substance is. On the pH scale, 7.0 is considered neutral, values below 7.0 are acidic, and those above 7.0 are alkaline.

Each plant species has a specific pH range that allows it to thrive, and for Calla Lilies, this range lies between slightly acidic to neutral levels (pH 6.0 to 7.0). At this level, the soil environment allows for optimal absorption of essential nutrients.

When the soil’s pH deviates from this range, it can restrict the plant’s ability to take in nutrients, even if they are present in the soil.

For instance, overly acidic soil can hinder the uptake of nutrients such as calcium, magnesium, and phosphorus. In contrast, overly alkaline soil can limit the availability of iron, manganese, and zinc.

Such restricted nutrient absorption can lead to nutrient deficiencies, manifesting in signs like yellowing leaves. Therefore, if your Calla Lilies are showing signs of yellowing leaves despite proper watering and nutrient supply, it might be time to check your soil’s pH levels.

You can easily test your soil’s pH using a home testing kit available at most garden centers. If the pH is outside the ideal range, it can be adjusted using soil amendments. Acidic soils can be balanced with lime, while alkaline soils can be corrected with sulfur or acidifying fertilizers.

Remember, maintaining balanced soil pH is fundamental for your Calla Lily’s health, contributing significantly to the vibrancy of its foliage.

Identifying Pests and Diseases

Keeping your Calla Lily in perfect health goes beyond providing just the right amount of water, light, and nutrients. Sometimes, despite our best efforts, we see those dreaded yellow leaves.

Identifying Pests and Diseases

One common and overlooked cause could be pests and diseases. It’s essential to familiarize yourself with the common pests and diseases that could affect your Calla Lilies, as early detection and treatment can save your beloved plant.

Common Pests Affecting Calla Lilies

Even the healthiest of plants can fall victim to pests. Among the many bugs that might fancy a nibble of your Calla Lily, aphids, spider mites, and thrips are the most common culprits.

These tiny invaders can cause noticeable damage and lead to issues like yellowing leaves. Let’s investigate these pests and their impact on your Calla Lily’s health.


Aphids are small, sap-sucking insects that can cause significant damage to your Calla Lily. They typically cluster on the underside of leaves or new growth. While a small population might not cause visible harm, a larger infestation can lead to yellowing and wilting leaves due to the loss of sap.

Aphids also produce a sticky substance called honeydew, which can lead to the growth of sooty mold, further complicating the issue.

Spider Mites

Spider mites are tiny pests that, like aphids, suck the sap from plants. They are challenging to spot due to their small size, but signs of infestation include:

  • Yellowing leaves with tiny speckles.
  • Webbing on the plant.
  • A general decline in plant health.

Unfortunately, spider mites can rapidly multiply, causing extensive damage if not addressed promptly.


Thrips are another group of tiny, sap-sucking pests. They often leave a distinctive damage pattern, with silver-grey patches and tiny black droppings on the leaves. Severe thrips infestation can lead to leaf yellowing, curling, and eventually dropping off.

Fungal and Bacterial Diseases

Plants are susceptible to various fungal and bacterial diseases, and Calla Lilies are no exception. Some common diseases that could be causing yellow leaves include root rot, leaf spot, and powdery mildew.

Root Rot

As mentioned earlier, root rot is often a consequence of overwatering or poor soil drainage, causing the roots to become waterlogged and deprived of oxygen.

However, certain fungi and bacteria in the soil can exacerbate this condition, leading to the rapid decay of roots. Root rot can cause yellowing leaves, stunted growth, and if not treated, plant death.

Leaf Spot

Leaf spot disease is a common issue among many plants, caused by several types of fungi and bacteria. This disease often manifests as yellowing leaves with black, brown, or red spots. These spots may have a yellow halo around them. Leaf spot can be problematic as it reduces the plant’s photosynthetic ability, affecting its overall health.

Powdery Mildew

Powdery mildew is a widespread fungal disease that appears as white to gray powdery spots on leaves, stems, and sometimes flowers. While it might not directly cause yellowing, severe infections can lead to yellow leaves, leaf drop, and reduced plant vigor.

Environmental Factors

As resilient as Calla Lilies are, they’re not impervious to their surroundings. The environment in which they grow can profoundly impact their health and vibrancy.

Two crucial environmental factors that can cause yellowing of leaves are lighting and temperature. Unfavorable conditions in either of these areas can lead to stress and potential health problems in your Calla Lilies.

Environmental Factors

Light Requirements

When it comes to light, striking the right balance is key for a thriving Calla Lily.

Effects of Insufficient Light

Calla Lilies love light. However, if they don’t receive enough, you might notice the leaves turning yellow and the plant appearing ‘leggy’ as it stretches toward the light source. Insufficient light hinders the plant’s ability to photosynthesize effectively, affecting its overall health and growth.

Effects of Excessive Light

Conversely, while Calla Lilies enjoy plenty of light, they’re not fans of intense, direct sunlight. Too much sunlight can lead to scorched leaves that turn yellow and brown. It can also dehydrate the plant quickly, leading to additional stress and potential yellowing.

Temperature Sensitivity

Temperature also plays a pivotal role in maintaining the lush green leaves of your Calla Lily.

Cold Stress

Calla Lilies are warm-loving plants. When the temperature drops below 55°F (12°C), they start showing signs of stress. This stress manifests as yellowing leaves, slowed growth, and the foliage can wilt and die in severe cases.

Heat Stress

Conversely, temperatures above 75°F (24°C) can lead to heat stress. When too hot, the plant may expire excessively, leading to dehydration. This dehydration can result in the leaves turning yellow, wilting, and eventually dropping off.

Not Fulfilling Nutritional Needs

Much like us, plants also need a well-balanced diet to thrive. When Calla Lilies don’t receive the nutrients they need, the deficiency can manifest as yellowing leaves. Let’s delve into the details of nutritional requirements for these stunning plants.

Not Fulfilling Nutritional Needs

Lack of essential Nutrients for Calla Lilies

A healthy Calla Lily is the result of a combination of essential nutrients, including nitrogen (N), phosphorus (P), and potassium (K), which are the major building blocks for plant growth.

Secondary nutrients like calcium (Ca), magnesium (Mg), and sulfur (S), and trace elements like iron (Fe), manganese (Mn), zinc (Zn), and others also play crucial roles in supporting the overall health and vitality of the plant.

Nutrient Deficiencies

A Calla Lily suffering from a deficiency in any of these vital nutrients will show signs of distress, one of the most apparent being yellowing leaves.

For example, nitrogen deficiency often results in pale green or yellow leaves because nitrogen is a key component of chlorophyll, the pigment responsible for the leaf’s green color.

On the other hand, a deficiency in iron or magnesium can cause yellowing between the leaf veins, a condition known as chlorosis.

Wrong Fertilization Practices

Sometimes, our efforts to provide nutrition can go awry even with the best intentions.

Organic vs. Synthetic Fertilizers

A plethora of fertilizers are available in the market, both organic and synthetic. Organic fertilizers are gentler and less likely to burn plants but may take longer to show effects.

Synthetic fertilizers, on the other hand, can provide nutrients quickly but can easily lead to over-fertilization if not used correctly.

Improper Fertilizer Application Schedule

The timing and frequency of fertilizer application also play a critical role. Applying fertilizer to Calla Lilies when they are dormant, for instance, can do more harm than good. Similarly, too frequent applications can lead to an overabundance of certain nutrients, causing toxicity that may result in yellow leaves.

How to Fix Calla Lily Leaves Turning Yellow?

Now that we’ve explored the common reasons behind the yellowing of Calla Lily leaves, it’s time to arm ourselves with knowledge on how to turn things around. It’s not just about fixing the issue, but also about creating a healthier environment for your Calla Lilies to thrive.

Let’s explore how to revive your plant and restore its lush green appeal.

How to Fix Calla Lily Leaves Turning Yellow

Identifying the Underlying Cause

Before you can initiate the revival of your Calla Lilies, it’s crucial to pinpoint the cause of their discoloration. As we’ve seen, several factors can contribute to yellowing leaves. Let’s break down the steps for identifying the possible culprits.

Natural Aging Vs. Other Factors

When you notice the leaves on your Calla Lilies taking on a yellow hue, don’t fret immediately. It’s important to remember that leaves, like every living thing, have a lifecycle – born vibrant and green, they age, turn yellow, and eventually fall off.

So, if you’re observing yellowing in the oldest, lowest leaves, rest easy knowing it’s a natural part of your plant’s growth and rejuvenation cycle. However, if younger leaves or most of the foliage are becoming yellow, it’s a red flag that something else is going wrong.

Observing Watering Practices

Watering seems straightforward enough, but it’s a fine balancing act. Each plant species has a Goldilocks zone for watering – not too much, not too little, but just right. For Calla Lilies, they enjoy evenly moist soil. Overwatering can cause their roots to become waterlogged and oxygen-starved, leading to yellowing leaves.

In contrast, underwatering can lead to dehydration, causing the plant to pull water from the leaves, resulting in a similar yellow appearance.

Carefully observing your watering practices, taking note of the soil moisture levels a couple of inches below the surface before each watering, can help you adjust your routine for your plant’s needs.

Assessing Soil Conditions

Healthy soil is to a plant what a balanced diet is to us – it’s their source of nutrition, water, and oxygen. Calla Lilies prefer a loose, well-draining soil with a slightly acidic pH between 6.0 and 6.5. If the soil is heavy and water-logged, or too alkaline or acidic, it can lead to nutrient lockout – even if the nutrients are present, the plant can’t absorb them, leading to yellowing leaves.

A soil test can help you understand your soil’s composition and pH, letting you amend it as necessary to create the ideal growing conditions for your Calla Lilies.

Checking for Pests and Diseases

Calla Lilies are susceptible to disease and pests, which can cause leaf yellowing like any living thing. Inspect the leaves for any signs of infestation – tiny bite marks, a sticky residue (honeydew), or the pests themselves.

Aphids, spider mites, and thrips are common culprits that sap the life out of the leaves, leading to yellowing.

Also, look for signs of diseases like powdery mildew or leaf spot, which manifest as white powdery patches or dark spots on the leaves. If you notice any of these signs, it’s time to roll up your sleeves and get down to pest control and disease management.

Adjusting Watering Practices

The art of watering is more than just hydrating your plants. It’s about understanding their unique requirements and adjusting your watering practices accordingly.

Calla Lilies, for instance, aren’t too picky but prefer consistency. Let’s dive into some pro tips to get the watering just right.

Adjusting Watering Practices

Pro Tips for Proper Watering

Frequency and Amount

Calla Lilies like their soil to be evenly moist, but not waterlogged. Typically, watering them once every few days is enough to maintain the soil’s moisture levels.

However, you must adjust this frequency based on the climate and season. For instance, you might need to water them more frequently during hot, dry summer months. Always check the soil before watering – if it’s dry up to 2 inches (about 5 cm) below the surface, it’s time to water your plant.

Watering Techniques

Avoid watering from above as wet leaves can attract diseases. Instead, water at the base of the plant, ensuring the water reaches the roots but doesn’t pool around them. If possible, water in the morning so that any accidental splashes on the leaves can dry out over the day.

If your plant is potted, ensure adequate drainage holes to prevent waterlogging. Mastering these watering techniques will go a long way in maintaining the vibrant green of your Calla Lily’s leaves.

Soil Management

Getting your hands dirty with soil isn’t everyone’s cup of tea, but understanding and managing the soil is vital if you’re committed to keeping your Calla Lilies thriving. Let’s explore some key aspects of soil management for these delicate plants.

Improving Drainage

Good drainage is critical for Calla Lilies. Stagnant water in the soil can lead to root rot, rapidly turning your lush green leaves yellow.

If you’re growing your plants in pots, ensure enough drainage holes. Consider adding coarse sand or perlite to the soil mix for garden planting. This not only improves drainage but also promotes healthy root growth.

Addressing Nutrient Deficiencies

Like all plants, Calla Lilies need a balanced mix of essential nutrients for optimal growth. Regularly enrich your soil with organic matter like compost or well-rotted manure.

This replenishes the soil nutrients and improves soil texture and water-holding capacity. If you notice nutrient deficiency symptoms, such as yellowing leaves or stunted growth, a balanced slow-release fertilizer can help.

Adjusting pH Levels

Calla Lilies prefer slightly acidic soil, with a pH between 6.0 and 6.5. If soil is too acidic or alkaline, it can affect nutrient uptake, leading to yellow leaves.

You can test your soil’s pH level using a soil test kit. Depending on the result, you may need to amend the soil with lime to raise the pH or sulfur to lower it. Proper soil management is the foundation of a healthy plant and a key factor in preventing yellowing leaves.

Pest and Disease Control

Addressing pests and diseases is as important as catering to your Calla Lilies’ nutritional needs. When these factors are unchecked, they can create havoc, leading to yellowing leaves, stunted growth, and eventually the death of the plant. Let’s delve into some strategies for pest and disease control.

Pest and Disease Control

Identifying Common Pests

Certain pests like Calla Lilies, including aphids, spider mites, and thrips. Regularly inspect your plants for any signs of these pests. Aphids are small green or black insects that cluster on new growth. Spider mites are tiny, spider-like creatures with a fine web on leaves and buds. Thrips are minute, slender insects that feed on leaves and flowers, causing silvery streaks and spots.

Recognizing Fungal and Bacterial Diseases

Fungal and bacterial diseases can also cause your Calla Lilies’ leaves to turn yellow. Look for signs of root rot, leaf spot, and powdery mildew. Yellow, wilting leaves and a foul smell from the roots characterize root rot. The leaf spot will show as brown or black spots on leaves, and powdery mildew appears as a white, powdery coating.

Integrated Pest Management (IPM) Techniques

Integrated Pest Management is a holistic approach to pest control that emphasizes understanding the life cycle of pests and their interaction with the environment. It encourages practices such as crop rotation and companion planting to control pests.

For Calla Lilies, encouraging beneficial insects like ladybugs that eat aphids, or using neem oil, a natural pesticide, can be part of an effective IPM strategy.

Using Safe and Effective Treatments

Choosing safe treatments is key to maintaining your garden’s and the environment’s health. For pests, consider using organic pesticides like neem oil or insecticidal soap.

For fungal diseases, copper-based fungicides can be effective. Always follow the manufacturer’s instructions when applying any treatment; remember, prevention is always better than cure!

Environmental Considerations

Even after ensuring proper watering and nutrient supply, some issues may arise due to environmental factors. Calla Lilies are sensitive to their surroundings, so paying attention to light conditions, temperature, and humidity is crucial for their well-being.

Optimal Light Conditions

Calla Lilies thrive in bright but indirect sunlight. If your lilies are indoors, place them near a window where they’ll get plenty of light but won’t be scorched by the sun’s rays.

If they’re outside, find a location that enjoys morning sunlight but is sheltered from the harsh afternoon sun. Too little light can lead to weak, leggy growth, while too much can cause leaf scorch.

Temperature Regulation

These plants prefer a warm temperature between 60 to 75 degrees Fahrenheit (15-24 degrees Celsius). When temperatures drop below 55°F (13°C), the plant may show signs of cold stress like yellowing leaves. Similarly, the plant may wilt in high heat conditions and show signs of heat stress.

Humidity Management

Humidity plays a vital role in maintaining the vibrancy of Calla Lilies. They prefer a higher humidity level, so consider using a humidity tray or a room humidifier, especially in dry climates or winter when indoor heating systems create arid conditions.

Regular misting can also help, but always aim to wet the air around the plant, not the leaves themselves, to avoid fungal diseases.

Nutritional Care

The final piece of the puzzle in rectifying yellowing leaves in Calla Lilies is ensuring they receive the right nutrition. Like all living organisms, these plants have specific dietary needs that, when met, promote vibrant health and stunning blooms.

Essential Nutrients for Calla Lilies

Calla Lilies require a balanced supply of macro and micro-nutrients. Key macronutrients include nitrogen (N), phosphorus (P), and potassium (K), while important micronutrients are iron (Fe), manganese (Mn), and zinc (Zn).

Nitrogen promotes leafy growth, phosphorus supports the root system and flowering, and potassium enhances plant vigor. Though needed in smaller quantities, micronutrients are critical for various metabolic processes.

Fertilization Best Practices

Fertilize your Calla Lilies monthly during the growing season with a balanced, water-soluble fertilizer. It’s best to water the plant thoroughly before fertilizing to prevent root burn. Also, reduce the frequency during dormancy to avoid excess nutrient build-up, which could contribute to leaf yellowing.

Choosing the Right Fertilizer

Selecting the right fertilizer can feel overwhelming, given the options available. A balanced, slow-release granular fertilizer, or a water-soluble variant with a balanced N-P-K ratio, is generally recommended. Also, ensure it contains essential micronutrients.

Organic options like compost or worm castings can also be beneficial, contributing nutrients and improving soil structure. Always follow package instructions to avoid over-fertilization, a common cause of leaf yellowing.

Proper Care and Maintenance

While addressing the specific issues causing leaf yellowing in your Calla Lilies is essential, it’s equally important to establish good care and maintenance practices.

Proper care can often prevent these issues from arising in the first place, keeping your lilies vibrant and healthy throughout the year. Explore key care steps in maintaining a thriving Calla Lily plant.

Proper Care and Maintenance

Pruning Yellow Leaves

Pruning isn’t just about aesthetics; it plays a crucial role in maintaining the health of your Calla Lilies. It helps you remove the yellowing leaves, which can hamper the plant’s growth and spread diseases if left unchecked.

To prune safely, use clean, sharp tools to reduce the risk of transmitting disease between plants. Cut the yellowing leaves off at the base of the stem, but be careful not to damage healthy tissue.

Regularly inspect your plant for signs of yellowing or disease for preventative pruning, and prune as needed. This helps to increase the plant’s overall health and vigor.

Regular pruning also encourages better air circulation, reducing the chances of fungal diseases, and allows more light to reach the heart of the plant.

Repotting and Transplanting

Sometimes, despite your best efforts, the Calla Lily may still experience stress and its leaves may turn yellow. One reason could be the plant has outgrown its current pot, becoming root-bound. This is when the roots take up so much space that they replace the soil in the pot.

Signs of a root-bound plant include slowed growth, wilting, and yellowing leaves, despite adequate water and nutrition.

If your plant shows these signs, it’s time to repot. Start by gently loosening the soil around the edges of the pot. Carefully lift the plant, maintaining as much of the root ball as possible. Prepare a larger pot with fresh, well-draining soil and make a large hole to accommodate the root ball.

Place the plant in the new pot, backfill with soil, and water thoroughly. Repotting gives your Calla Lily more room to grow and access fresh, nutrient-rich soil.

Mulching Benefits

Mulching is one of those gardening practices that can significantly impact your Calla Lily’s health, particularly when dealing with yellowing leaves. Applying a layer of mulch around your Calla Lily offers dual benefits of moisture retention and temperature regulation.

Mulching Benefits

Regarding moisture, mulch acts like a sponge, holding onto water and slowly releasing it into the soil. This steady water supply can prevent underwatering and overwatering issues, keeping your plant hydrated.

Temperature regulation is the other significant advantage of mulching. Mulch is an insulating barrier, protecting your Calla Lily from extreme temperatures.

During hot spells, mulch keeps the soil cool and protects the roots from heat stress. It helps keep the soil warm in cold conditions, safeguarding against frost damage. Thus, mulch can be a great tool to help keep your Calla Lily’s leaves green and vibrant.
