19 Common Problems With Kalanchoes

Ah, the fabulous Kalanchoe! These vibrant succulents are beloved for their cheerful blooms and easygoing nature. Yet, like any good thing, they come with their quirks. If you've got a Kalanchoe or are thinking about getting one, it's helpful to know the bumps you might hit along the way. That's why we've rounded up 19 common problems you might face with these charming plants.

We'll go over everything from watering woes to pesky pests, and even a few surprises you might not expect. Each section will offer practical advice and tips, sprinkled with relatable examples to keep things interesting. Ready to get to know your Kalanchoe a little better? Let's get started!

1. Overwatering: The Most Common Culprit

Overwatering is the number one issue with Kalanchoes. These succulents store water in their leaves, so they don't need frequent watering. When you give them too much love (in the form of water), their roots can rot. Root rot is a sneaky villain because it happens underground where you can’t see it.

Here's how to avoid this pitfall:

• Let the soil dry out completely between waterings. Test it by sticking your finger an inch into the soil. If it's dry, it's time for a drink.
• Use well-draining soil. A cactus or succulent mix works wonders.
• Ensure your pot has drainage holes. This allows excess water to escape instead of drowning your plant.

If you suspect root rot, gently remove the plant from its pot and check the roots. Healthy roots are white and firm, while rotten ones are brown and mushy. Trim away the damaged roots and repot your Kalanchoe in fresh soil.

2. Underwatering: The Other Side of the Coin

On the flip side, underwatering can also be an issue. Though these plants are drought-tolerant, they do need water to thrive. You might notice wrinkled leaves or slow growth if your Kalanchoe's too thirsty.

To keep your plant happy:

• Water when the soil is completely dry, but don't wait too long. A consistent routine helps.
• Increase watering slightly during the growing season (spring and summer) when the plant is more active.

Think of it like this: if you’re parched after a long hike, a sip of water feels amazing, but too much might make you queasy. It’s all about balance.

3. Insufficient Light: A Dull Existence

Kalanchoes love bright, indirect sunlight. If they're stuck in a dim corner, their colors may fade, and they could stop blooming. A plant without enough light is like a person without coffee—lacking energy and happiness.

To brighten their day:

• Place them near a south or west-facing window.
• Use sheer curtains to filter intense midday sun.
• Rotate the pot occasionally to ensure even light exposure.

If moving your plant isn't an option, consider supplementing with a grow light. It's like giving your Kalanchoe a sunbath even on the cloudiest days.

4. Too Much Sun: A Scorched Situation

While Kalanchoes love light, too much direct sun can burn them. Scorched leaves turn brown and crispy, much like your skin after a day at the beach without sunscreen.

Protect your plant by:

• Moving it out of direct afternoon sun.
• Using a sheer curtain to diffuse intense sunlight.
• Checking for signs of sunburn and adjusting its location accordingly.

Remember, it’s all about finding that sweet spot where your plant gets the light it needs without the burn.

5. Temperature Extremes: Not Too Hot, Not Too Cold

Kalanchoes thrive in temperatures between 60-85°F (15-29°C). They dislike sudden changes, much like us when we step out of a cozy house into a freezing winter day.

Avoid these pitfalls by:

• Keeping your plant away from drafty windows or doors.
• Maintaining a stable indoor temperature if possible.
• Bringing outdoor plants in before temperatures drop too low.

Think of your Kalanchoe as a fair-weather friend who’s happiest in mild conditions.

6. Pests: The Unwanted Guests

Even the most vigilant plant parent can encounter pests like aphids, mealybugs, or spider mites. These tiny invaders can sap the life from your plant, leaving it looking sad and unhealthy.

To keep pests at bay:

• Regularly inspect leaves for signs of infestation.
• Wash off bugs with a gentle stream of water or wipe with a damp cloth.
• Use insecticidal soap or neem oil for persistent problems.

Stay vigilant! A little extra attention can prevent a small pest problem from becoming a full-blown invasion.

7. Nutrient Deficiency: A Lackluster Look

Kalanchoes don’t require heavy feeding, but a lack of nutrients can lead to pale leaves and stunted growth. Imagine trying to run a marathon without breakfast—your plant needs a little fuel to flourish.

Here’s how to give them a boost:

• Fertilize with a balanced, water-soluble fertilizer during the growing season.
• Follow package instructions to avoid over-fertilizing, which can harm the plant.
• Skip feeding during the dormant winter months.

Think of it as giving your Kalanchoe a healthy snack, just enough to keep it going strong.

8. Pot-Bound Roots: Cramped Quarters

If your Kalanchoe looks like it’s struggling despite your best efforts, it might be pot-bound. When roots outgrow their container, they can’t absorb nutrients properly, and the plant can become stressed.

Free your plant by:

• Checking for roots growing out of drainage holes.
• Gently removing the plant from its pot to inspect the roots.
• Repotting into a container one size larger with fresh soil.

Giving your Kalanchoe more space is like moving from a crowded studio apartment to a spacious one-bedroom—it’s a breath of fresh air.

9. Leaf Drop: The Mystery of Falling Leaves

Leaf drop can be puzzling and frustrating. Often, it’s a sign of stress from changes in light, temperature, or water. It’s like when you’re stressed and accidentally drop your keys—things just slip.

To prevent leaf drop:

• Maintain a consistent care routine to minimize stress.
• Address any sudden changes in environment promptly.
• Ensure the plant isn’t exposed to drafts or temperature swings.

With a little patience and attention, your Kalanchoe will hold onto its leaves and thrive.

10. Leggy Growth: A Stretch for Light

Kalanchoes can become leggy when they stretch toward light. This results in long, spindly stems with sparse leaves—a bit like a person reaching for the last cookie on a high shelf.

Combat legginess by:

• Ensuring the plant receives enough bright, indirect light.
• Rotating the pot regularly for even growth.
• Pruning back overgrown stems to encourage bushier growth.

A little trim here and there can do wonders for maintaining a compact, happy plant.

11. Fungal Infections: An Unwelcome Fungus Among Us

Fungal infections like powdery mildew can cloak your Kalanchoe in a white, dusty film. This often occurs in humid conditions with poor air circulation—a bit like leaving your laundry in a damp basement.

To fend off fungi:

• Keep humidity levels in check and provide good airflow.
• Avoid overhead watering to prevent moisture on leaves.
• Remove affected leaves and treat with a fungicide if necessary.

Think of it as maintaining a clean environment where your plant can breathe easy.

12. Edema: The Unexpected Swell

Edema occurs when plants absorb more water than they can use, leading to swollen leaves with blisters or corky spots. It’s like drinking too much water too quickly—your plant simply can’t handle it.

Prevent edema by:

• Watering only when the soil is dry to the touch.
• Ensuring proper drainage to allow excess water to escape.
• Keeping humidity levels moderate to low.

A little moderation goes a long way in keeping your Kalanchoe healthy and blemish-free.

13. Flowering Problems: When Blooms Won’t Budge

Kalanchoes are known for their beautiful blooms, but sometimes they refuse to flower. This can be disappointing, like a cake that won’t rise. A lack of light is often the culprit.

Encourage flowering by:

• Ensuring the plant gets enough bright, indirect light.
• Allowing a rest period with reduced light and watering after flowering.
• Fertilizing lightly during the growing season to support bud development.

With a little TLC, your Kalanchoe will reward you with vibrant blooms.

14. Incorrect pH Levels: A Balancing Act

Kalanchoes prefer slightly acidic to neutral pH levels (6.0-7.0). If the soil is too acidic or alkaline, nutrient uptake can be hindered, much like trying to drink through a clogged straw.

Maintain optimal pH by:

• Using a soil mix designed for cacti and succulents.
• Testing soil pH periodically and adjusting with amendments if needed.
• Avoiding excessive use of acidic fertilizers.

Keeping your plant’s pH in check ensures it gets the nutrients it needs to thrive.

15. Transplant Shock: The Adjustment Period

After repotting, a Kalanchoe might experience transplant shock, showing signs of stress like wilting or leaf drop. This is like moving to a new city—it takes time to adjust.

Ease the transition by:

• Being gentle when handling the plant and roots.
• Watering lightly after repotting to help settle the soil.
• Placing the plant in a familiar, stable environment to reduce stress.

Give your Kalanchoe a little time, and it will settle into its new home.

16. Toxicity Concerns: Safe for Pets?

Kalanchoes are mildly toxic to pets if ingested, causing symptoms like vomiting or diarrhea. If you have curious critters at home, it’s worth taking precautions.

Keep your pets safe by:

• Placing plants out of reach of pets.
• Training pets to avoid houseplants.
• Monitoring for signs of ingestion and contacting a vet if necessary.

A little awareness goes a long way in keeping both your plants and pets happy and healthy.

17. Incorrect Pot Size: Just the Right Fit

Choosing the wrong pot size can lead to problems. A pot that's too large retains excess moisture, while a pot that's too small can restrict growth. It’s a bit like wearing shoes that don’t fit—uncomfortable and limiting.

Find the perfect pot by:

• Selecting a pot that’s one size larger than the current root ball when repotting.
• Ensuring the pot has drainage holes to prevent waterlogging.
• Using a pot made of breathable material like terracotta for better moisture control.

A well-chosen pot gives your Kalanchoe room to grow while keeping it comfortable.

18. Incorrect Pruning: Snip, Snip, Hooray!

Pruning Kalanchoes encourages bushier growth and removes dead or damaged leaves. But incorrect pruning can harm the plant, much like a bad haircut can leave you feeling less than fabulous.

Prune with confidence by:

• Using clean, sharp scissors or pruning shears.
• Trimming back leggy stems to promote fullness.
• Removing spent blooms to encourage new growth.

A little know-how turns pruning from a daunting task into a rewarding routine.

19. General Neglect: The Silent Saboteur

Sometimes, life gets busy, and plants get neglected. Kalanchoes are forgiving, but they still need attention to thrive. Neglect can lead to a host of issues like leaf drop, pests, and poor growth.

Keep your plant in top shape by:

• Setting a reminder for watering and care tasks.
• Regularly checking for signs of pests or disease.
• Taking a moment to admire your plant and notice any changes.

With a little love and attention, your Kalanchoe will continue to brighten your home.
