- Signs of Overwatering:
- Yellowing leaves before browning
- Wilting despite wet soil
- Foul smell from the soil
2. Underwatering
On the flip side, underwatering can also cause brown leaves. If the soil dries out completely, the plant will struggle to absorb moisture.
- Signs of Underwatering:
- Dry, crispy leaves
- Leaf drop
- Soil pulling away from the pot edges
3. Sunburn and Excessive Sunlight
Kalanchoes thrive in bright light, but too much direct sunlight can lead to sunburn. Brown patches or crispy edges are indicators of this issue.
- Signs of Sunburn:
- Brown, crispy leaf tips
- Leaves turning pale or bleached
4. Pest Infestation
Pests such as aphids or mealybugs can wreak havoc on your Kalanchoe, causing brown leaves. For more information on how to handle this, check out our guide on causes and solutions for brown spots on Kalanchoe leaves.
- Signs of Pests:

Role of Nutrient Deficiencies in Leaf Browning
Ever looked at your Kalanchoe and thought, “Why are the leaves turning brown?”
You might be surprised to learn that nutrient deficiencies could be the culprit.
Plants, just like us, need a balanced diet to thrive. When they lack essential nutrients, it can lead to all sorts of issues, including those dreaded brown leaves.
Key Nutrients to Consider
- Nitrogen: This is crucial for healthy leaf growth. A nitrogen deficiency can cause older leaves to yellow and eventually brown.
- Potassium: Helps with water regulation and overall plant health. Without it, you might see browning at the leaf tips.
- Magnesium: Important for chlorophyll production. A lack of magnesium can lead to interveinal chlorosis, where the spaces between the veins turn yellow, leaving the veins green. Over time, this can lead to browning as well.
Signs of Nutrient Deficiencies
- Yellowing Leaves: Often the first sign of nutrient issues.
- Brown Tips or Edges: Look for crispy edges; this could indicate a potassium deficiency.
- Stunted Growth: If your Kalanchoe isn’t growing as it should, it might be craving some nutrients.
How to Fix It
- Fertilize: Use a balanced, water-soluble fertiliser every 4-6 weeks during the growing season. Look for one with micronutrients included.
- Soil Check: Sometimes, it’s the soil that’s lacking. Ensure you’re using a well-draining potting mix that retains some nutrients.
- Leaf Inspection: Regularly check your leaves. If you spot signs of deficiency, act fast!
As we explore the best practices for maintaining your Kalanchoe, it’s crucial to remember that proper watering and soil care can significantly impact the health of your plant and prevent brown leaves.
### Understanding Watering Needs
Kalanchoe plants thrive in well-draining soil and prefer to dry out between waterings. Here are some essential tips for effective watering:
– **Check Soil Moisture**: Before watering, stick your finger about an inch into the soil. If it feels dry, it’s time to water.
– **Watering Schedule**: During the growing season (spring and summer), water every 1-2 weeks. In the dormant season (fall and winter), reduce this to once every 2-3 weeks.
– **Watering Technique**: When you water, do so thoroughly until water drains from the bottom of the pot. This ensures the roots receive adequate moisture.
### Choosing the Right Soil
The right soil is equally important for your Kalanchoe’s health. Opt for:
– **Cactus Mix**: A commercial cactus or succulent mix provides excellent drainage.
– **DIY Soil Mix**: Create your own by combining regular potting soil with perlite or sand for improved aeration.
### Pot Considerations
Using the right pot can also make a difference:
– **Drainage Holes**: Always select pots with drainage holes to prevent water from pooling.
– **Material Matters**: Terracotta pots are great for succulents as they allow for moisture evaporation.
### Seasonal Adjustments
Adjust your care based on the seasons:
– **Summer**: Increase watering frequency if the weather is particularly hot.
– **Winter**: Cut back on watering to avoid root rot during the dormant period.
By implementing these best practices for watering and soil care, you can significantly reduce the risk of brown leaves and ensure your Kalanchoe thrives.
