Common Causes of Yellowing in Kalanchoe Bottom Leaves

Have you noticed your Kalanchoe’s bottom leaves turning yellow? This can be a common issue for many plant enthusiasts, and understanding the causes is the first step toward a healthier plant.

Overwatering

One of the primary culprits behind yellowing leaves is overwatering. Kalanchoes are succulents that thrive in dry conditions. When the soil remains soggy, it can lead to root problems, resulting in yellow leaves.

Poor Drainage

Lack of adequate drainage can exacerbate the overwatering issue. If your pot doesn’t allow excess water to escape, the roots can suffocate and rot, leading to yellowing leaves.

Inadequate Lighting

Kalanchoes require bright, indirect sunlight. Insufficient light can cause the plant to become weak, leading to yellowing leaves. Conversely, too much direct sun can scorch the leaves, also resulting in yellowing.

Nutrient Deficiencies

Deficiencies in essential nutrients, particularly nitrogen and zinc, can manifest as yellowing leaves. A balanced fertiliser can help restore the necessary nutrients.

Pest Infestations

Pests such as aphids or mealybugs can sap the vitality from your Kalanchoe, leading to yellowing leaves. Regularly inspecting your plant can help catch these infestations early.

Temperature and Humidity

Kalanchoes prefer a stable environment. Extreme temperature changes or high humidity can stress the plant, causing yellow leaves.

Root Rot

If you observe yellowing leaves alongside wilting, root rot may be the issue. This condition often results from prolonged overwatering and requires immediate attention. For more detailed information on how to manage this, check out our Complete Care Guide for Kalanchoe Flapjack Plant.

Overwatering and Its Effects on Kalanchoe Health

Are your Kalanchoe’s bottom leaves turning yellow? You might be wondering if you’re giving it too much love—specifically, too much water.

Overwatering is one of the most common culprits when it comes to yellowing leaves in Kalanchoe plants. These beauties thrive in dry conditions, so when you drown them, they can really struggle.

What Happens When You Overwater?

Root Suffocation: Too much water can lead to root suffocation. Roots need air, and if they’re sitting in soggy soil, they can’t breathe.
Nutrient Lockout: Overwatered plants often can’t absorb nutrients properly. This can lead to deficiencies, making those vibrant leaves turn yellow.
Fungal Issues: Excess moisture creates a perfect environment for root rot and other fungal diseases. Once these set in, it can be tricky to save your plant.

Signs You’re Overwatering

Yellowing Leaves: The first sign is usually the bottom leaves turning yellow. If you notice this, it’s time to check your watering routine.
Wilting: Ironically, overwatered plants can also appear wilted. It’s a clear sign that something’s off.
Mushy Roots: If you pull your plant out of the pot and the roots feel mushy or brown, you might be dealing with root rot.

How to Fix Overwatering Issues

Check the Soil: Stick your finger into the soil about an inch deep. If it’s wet, hold off on watering.
Adjust Your Watering Schedule: Kalanchoes generally need water every 2-3 weeks, depending on the season.
Improve Drainage: Make sure your pot has drainage holes and consider using a well-draining soil mix.
Repot if Necessary: If root rot has set in, you might need to repot your plant in fresh soil, trimming away any damaged roots.

III. The Role of Drainage in Preventing Yellow Leaves

If you’ve noticed your Kalanchoe’s bottom leaves turning yellow, poor drainage could be a significant factor.

Why Drainage Matters

Good drainage is crucial for Kalanchoe health. Without it, excess water can accumulate, leading to root problems that manifest as yellowing leaves.

Root Suffocation: When roots sit in waterlogged soil, they can suffocate, preventing them from absorbing essential nutrients.
Fungal Growth: Excess moisture creates an environment for fungal infections, which can further damage the roots.

How to Ensure Proper Drainage

Here are some straightforward tips to improve drainage for your Kalanchoe:

Choose the Right Pot:
- Opt for pots with drainage holes.
- Consider using terracotta pots, which allow for better airflow.
Use Well-Draining Soil:
- A cactus or succulent mix is ideal.
- You can also mix regular potting soil with sand or perlite to enhance drainage.
Elevate the Pot:
- Place your pot on small feet or stones to allow excess water to escape.
Water Wisely:
- Always check the soil moisture before watering.
- Water deeply but infrequently, allowing the soil to dry out between watering sessions.

By ensuring proper drainage, you can significantly reduce the risk of yellow leaves in your Kalanchoe.

How Lighting Impacts Kalanchoe Leaf Health

Have you ever noticed your Kalanchoe’s leaves turning yellow, and wondered if lighting could be the culprit?

Lighting plays a crucial role in the overall health of your Kalanchoe.

Understanding Light Needs:

Kalanchoe thrives in bright, indirect sunlight.
Too much direct sunlight can scorch the leaves, leading to yellowing.
Conversely, insufficient light can cause the plant to become leggy and weak, resulting in a similar yellowing effect.

Signs of Improper Lighting:

Yellow leaves that appear crispy or burnt indicate too much sun.
If your Kalanchoe is stretching towards the light, it may not be getting enough.

Optimal Lighting Solutions:

Place your Kalanchoe near a south or west-facing window for optimal exposure.
If direct sunlight is too intense, use sheer curtains to diffuse the light.
Rotate your plant every few weeks to ensure even light distribution.

Adjusting for Seasons:

In winter, when daylight hours are shorter, consider using a grow light to supplement natural light.
Keep an eye on your plant’s response to seasonal changes; adjust its position as needed.

Nutrient Deficiencies: Zinc and Nitrogen

Have you noticed your Kalanchoe’s bottom leaves turning yellow despite consistent care? Nutrient deficiencies could be the culprit, specifically a lack of zinc and nitrogen.

Understanding Nutrient Roles:

Nitrogen: Essential for leaf growth and overall plant vitality. A deficiency often leads to yellowing leaves, particularly older ones, as the plant reallocates nitrogen to newer growth.
Zinc: Crucial for chlorophyll production and enzyme function. A lack of zinc can result in interveinal chlorosis, where the leaf turns yellow between the veins, while the veins remain green.

Signs of Deficiencies:

Yellowing leaves, especially at the bottom.
Stunted growth or smaller leaves.
Leaf drop or wilting.

How to Address Deficiencies:

Soil Testing: Conduct a soil test to determine nutrient levels.
Fertilisation:
- Use a balanced fertiliser with adequate nitrogen content.
- Consider a zinc supplement if soil tests indicate a deficiency.
Organic Options:
- Incorporate compost or well-rotted manure to naturally enrich the soil.
- Use foliar sprays containing zinc for quick absorption.
Observation: Monitor your Kalanchoe for improvement after treatment. Adjust your fertilisation schedule based on its response.
