Growing Kalanchoe Outdoors
Looking to grow Kalanchoe outdoors in the ground? You’re in the right place. As a seasoned gardener, I’ve found that the key to thriving Kalanchoe is selecting the ideal planting site. Opt for a spot that gets plenty of sunlight and offers well-draining soil. This ensures your Kalanchoe will get the nutrients and light it needs to flourish.
Preparing the Soil
Preparing the soil is crucial. Enrich the ground with organic matter to boost fertility and drainage. Once your soil is ready, choose the best Kalanchoe varieties for outdoor planting.
Recommended Varieties
- Kalanchoe blossfeldiana – Perfect for garden beds.
With the right care, your Kalanchoe will reward you with vibrant, long-lasting blooms.
Ideal Planting Site for Kalanchoe
When considering where to plant Kalanchoe, many gardeners often wonder about the best conditions for this resilient succulent.
Location Matters
The ideal planting site for Kalanchoe should offer:
- Well-draining soil: Kalanchoe thrives in soil that allows excess water to escape. This prevents root rot and encourages healthy growth.
- Sunlight: A location that receives at least six hours of sunlight each day is essential. Kalanchoe loves bright light, and insufficient sunlight can lead to leggy growth and fewer blooms.
- Protection from harsh elements: While Kalanchoe is hardy, it benefits from some shelter against strong winds and heavy rain. A spot near a wall or fence can provide this protection.
Soil Type
The soil should be:
- Sandy or loamy: This type of soil enhances drainage and reduces the risk of waterlogging.
- Slightly acidic to neutral: A pH range of 6.0 to 7.0 is optimal for Kalanchoe.
Accessibility
Choose a site that is easy to access for maintenance tasks such as watering and pruning. For more detailed information on how to plant Kalanchoe, you can refer to our step-by-step guide. Additionally, if you are looking for specific varieties, our comprehensive Kalanchoe species list can be very helpful.
Preparing the Soil for Outdoor Kalanchoe
So, you’ve picked the perfect spot for your Kalanchoe, and now it’s time to get your hands dirty.
But here’s the thing: not all soil is created equal.
What’s the Big Deal About Soil?
Kalanchoe thrives in well-draining soil. If your soil retains too much moisture, you might end up with root rot, and nobody wants that.
Here’s how to prepare your soil for planting:
- Check the Drainage: Dig a small hole about 12 inches deep. If water pools in there after a rain, you’ll need to improve drainage.
- Mix in Sand or Perlite: This helps break up heavy soil. Aim for a mix that’s about 50% garden soil and 50% sand or perlite.
- Add Organic Matter: Compost is your best friend here. It enriches the soil while improving drainage. A couple of handfuls mixed in should do the trick.
- pH Level: Kalanchoe prefers a slightly acidic to neutral pH (around 6.0 to 7.0). You can test your soil with a simple kit from the garden centre.
Ready, Set, Go!
Once you’ve prepped the soil, it’s time to plant.

Steps for Planting Kalanchoe in the Ground
Planting Kalanchoe in the ground can be a rewarding experience, but knowing the right steps can make all the difference.
1. Choose the Right Time
Timing is crucial. The best time to plant Kalanchoe outdoors is during spring after the last frost. This allows the plant to establish its roots in warmer soil.
2. Select a Suitable Location
Find a spot that receives plenty of sunlight. Kalanchoe thrives in well-drained areas, so avoid places where water tends to pool.
Watering and Drainage Considerations
So, you’ve picked the perfect spot for your Kalanchoe, and now you’re probably wondering how to keep it thriving. One of the biggest concerns is watering and ensuring proper drainage.
Watering Tips:
- Frequency: Kalanchoe prefers to dry out between waterings. Aim to water every 2-3 weeks, but adjust based on the weather. If it’s hot and dry, you might need to water more often.
- Method: Water deeply but infrequently. This encourages the roots to grow deeper into the soil, making your plant stronger.
- Signs to Watch: If the leaves start to look wrinkled or shrivelled, it’s a sign your Kalanchoe needs a drink. On the flip side, yellowing leaves might indicate overwatering.
Drainage is Key:
- Soil Type: Ensure you’re using well-draining soil. A mix designed for succulents or cacti works wonders.
- Planting Position: If your Kalanchoe is in a spot where water tends to pool, consider elevating it or creating a raised bed. This helps prevent root rot.
- Container Consideration: If you’re planting in pots, make sure they have drainage holes. No one wants soggy roots!
Sunlight and Temperature Requirements
When considering outdoor planting for Kalanchoe, you might be wondering about the ideal sunlight and temperature conditions.
Kalanchoe thrives in bright, indirect sunlight but can adapt to full sun in cooler climates. Here are some key points to keep in mind:
Acclimatizing Indoor Kalanchoe for Outdoor Growth
So, you’ve got your indoor Kalanchoe thriving, and now you’re thinking about moving it outdoors. Sounds exciting, right? But how do you make sure it doesn’t freak out in the new environment? Let’s dive into acclimatizing your Kalanchoe for outdoor growth.
Why Acclimatize?
Jumping straight from a cozy indoor setting to the great outdoors can be a shock for your plant. Acclimatization helps ease that transition, reducing stress and ensuring your Kalanchoe adapts well to its new digs.
Steps for Acclimatization:
- Start Slow:
- Begin by placing your Kalanchoe outside for a couple of hours each day.
- Gradually increase the time over a week or two.
- Choose the Right Spot:
- Find a shaded area to start with. Direct sunlight can be too harsh initially.
- Monitor Temperature:
- Keep an eye on the weather. Avoid exposing your plant to extreme temperatures.
- Watch for Signs:
- Look out for droopy leaves or discoloration. These could be signs your plant is stressed.
- Water Wisely:
- Water your Kalanchoe before moving it outside. This gives it a hydration boost.
- Fertilize Lightly:
- If you’ve been fertilizing indoors, cut back a bit during acclimatization. Too much food can overwhelm it.
Final Touches:
Once your Kalanchoe seems comfy in its outdoor spot, you can gradually introduce it to more sunlight. It’s all about patience and observation.
Pruning and Maintenance Practices
When it comes to keeping your Kalanchoe thriving, pruning and maintenance are crucial steps that can make a significant difference. Many gardeners worry about how to properly care for their plants to ensure they flourish outdoors.
Why Prune Kalanchoe?
Pruning serves multiple purposes:
- Encourages Growth: Removing dead or wilted leaves stimulates new growth.
- Enhances Appearance: A well-pruned plant looks tidier and more attractive.
- Prevents Disease: Regularly removing unhealthy parts can help prevent the spread of disease.
When to Prune
- After Flowering: Trim back spent blooms and any damaged leaves.
- Spring: A light pruning in spring can help shape the plant for the growing season.
How to Prune
- Use clean, sharp scissors or pruning shears.
- Cut just above a leaf node to encourage new growth.
- Remove any stems that are leggy or overcrowded.
Maintenance Tips
In addition to pruning, consider these maintenance practices:
- Regular Inspection: Check your Kalanchoe for pests or signs of disease.
- Cleaning Leaves: Dust can accumulate on leaves, so gently wipe them with a damp cloth.
- Mulching: Apply a layer of mulch to help retain moisture and suppress weeds.

Overwintering Kalanchoe in Cold Climates
As we explore the nuances of outdoor Kalanchoe care, the challenge of overwintering in colder climates becomes paramount.
Why Overwintering Matters
Kalanchoe, being a succulent, thrives in warmer conditions. However, if you live in a region with harsh winters, you’ll need to take proactive steps to protect your plants from frost and freezing temperatures.
Key Strategies for Successful Overwintering

If possible, before the first frost, pot your Kalanchoe and bring it indoors.
Place them in a well-lit area, ideally near a south-facing window. - Mulching
For those left outdoors, apply a thick layer of mulch around the base.
This helps insulate the roots and retain warmth. - Covering Plants
Use frost cloths or blankets to cover your Kalanchoe during extreme cold spells.
Ensure they are well-ventilated to prevent moisture build-up. - Watering Adjustments
Reduce watering significantly in winter.
Allow the soil to dry out completely between waterings to prevent root rot. - Temperature Monitoring
Aim to keep the temperature above 5°C (41°F) if possible.
Consider using a greenhouse or cold frame for added protection.
