Can Kalanchoe Plants Be Planted Outside?

Kalanchoe is a popular houseplant known for its colorful and long-lasting flowers. With their tropical origin, some wonder if these plants can live outdoors. So can kalanchoe plants be planted outside?

The short answer is yes kalanchoe can be grown outside depending on the climate and variety. While they make great houseplants some kalanchoe thrive planted in the garden if given the right conditions.

Understanding Kalanchoe’s Outdoor Potential

Kalanchoe are native to tropical regions of Africa and Madagascar. Most varieties grow best in zones 10-12 and cannot tolerate frost or freezing temperatures. However, they can thrive outdoors year-round in warm climates.

The key benefit of growing kalanchoe outside is increased airflow. The constant circulation outdoors promotes healthy growth compared to stagnant indoor air. Kalanchoe also need ample sunlight to bloom, which outdoor spaces provide.

When considering moving a kalanchoe outside, it’s crucial to select a frost-tolerant variety suited for your zone. Popular outdoor varieties include K. daigremontiana, K. blossfeldiana, and K. thyrsiflora. Always research your specific variety’s needs.

Choosing the Right Kalanchoe Variety

With over 125 kalanchoe species, selecting the right one for outdoor planting can be tricky. The main factors to consider are climate, hardiness zone, sunlight needs, and soil drainage.

• Climate – Most kalanchoe thrive in zones 10-12 and cannot tolerate frost. Some varieties tolerate cooler zones 7-8. Choose based on your local climate.

• Hardiness Zone – Determine your zone and match it with your variety’s recommended zone. This ensures the plant can survive your winters.

• Sunlight – Kalanchoe need at least 4-6 hours of direct sun daily to bloom well. Select a sunny spot.

• Soil Drainage – Good drainage is essential. Amend soil with compost to improve aeration.

Popular outdoor varieties like K. blossfeldiana and K. daigremontiana check these key boxes. Always confirm your variety’s specific requirements before planting.

Preparing Kalanchoe for Outdoor Planting

Proper preparation helps kalanchoe transition outside without shock. The process called “hardening off” accustoms the plant to outdoor conditions gradually:

• Start by placing the plant in a shady spot outdoors 1-2 hours per day.

• Slowly increase the duration over 7-10 days until it’s adjusted to full sun.

• Prune off any dead or damaged parts and fertilize with a balanced, water-soluble fertilizer.

• Amend soil with compost or manure to improve drainage and nutrients if needed.

These steps prevent transplant shock and give kalanchoe the best start in its new outdoor environment. Monitor its progress and adjust care as needed.

Selecting the Best Outdoor Location

Choosing the right outdoor spot is vital for kalanchoe success. Key factors to consider include:

• Sunlight – Look for a spot with 4-6 hours of direct sun to encourage abundant blooms.

• Temperature – Kalanchoe prefer warm conditions between 65-75°F. Avoid frost-prone areas.

• Soil Quality – Well-draining soil enriched with organic matter is ideal. Amend if needed.

• Drainage – Prevent wet feet by planting in raised beds or containers for better drainage.

Providing optimal sun, warmth, soil, and drainage gives kalanchoe the conditions it needs to thrive outside. Monitor its needs and adjust conditions as required.

Planting and Caring for Kalanchoe Outdoors

When planting kalanchoe outside, dig a hole as deep as the root ball and backfill with enriched soil. Water thoroughly after planting and space plants 12-18 inches apart for airflow.

Ongoing care involves:

• Watering regularly when the soil dries out, taking care not to overwater.

• Applying a balanced fertilizer monthly during growing season.

• Deadheading spent blooms to encourage new flowers.

• Pruning leggy growth and removing dead leaves/stems.

• Protecting from pests like aphids and diseases like powdery mildew.

• Safeguarding from extreme weather with frost blankets or wind protection.

• Repotting every 1-2 years in well-draining soil.

By providing enriched soil, proper sunlight, and attentive care, kalanchoe can thrive planted outside.

Enjoying Thriving Outdoor Kalanchoe

With the right variety and conditions, kalanchoe can be successfully grown outside in many zones. The rewards of outdoor kalanchoe include:

• Attracting pollinators like bees and butterflies to your garden

• Providing a sense of accomplishment watching it flourish outside

• Enjoying their low-maintenance nature outdoors

• Appreciating their tropical beauty in your garden

• Experiencing their bright, cheery flowers during winter

By selecting suitable varieties, preparing plants properly, and providing attentive care, kalanchoe can thrive outside in suitable climates. Just be sure to offer protection from frost and extreme cold. With a little effort, you can enjoy their vibrant blooms outside your home.
