Propagating Caladium: Top Tips for Rhizome Division

6. Propagating Caladium: Top Tips for Rhizome Division

Are you looking to expand your caladium collection? One of the best ways to do so is by propagating through rhizome division. In this article, we will provide you with top tips on how to successfully divide caladium rhizomes to ensure healthy growth and beautiful foliage. Whether you are a seasoned gardener or a beginner, these tips will help you make the most out of your caladium propagation efforts.

Understanding Caladium Rhizomes

What are Caladium Rhizomes?

Caladium rhizomes are underground stems that store nutrients and water for the plant. They are essential for the growth and propagation of caladium plants. Rhizomes are responsible for producing new shoots and roots, allowing the plant to spread and thrive.

Types of Caladium Rhizomes

There are two main types of caladium rhizomes: tuberous and fibrous.

  • Tuberous rhizomes are thick, fleshy stems that store a large amount of nutrients and water. They are commonly found in larger caladium varieties and can produce multiple shoots and leaves.

  • Fibrous rhizomes are thinner, more delicate stems that have a fibrous texture. They are typically found in smaller caladium varieties and produce fewer shoots and leaves compared to tuberous rhizomes.

Understanding the type of rhizome your caladium plant has can help you determine the best propagation methods and care practices for your plant.

When to Divide Caladium Rhizomes

Caladium rhizomes should be divided when they become overcrowded and start to outgrow their container or planting area. Dividing them will help promote healthier growth and prevent them from competing for nutrients and space.

Signs that Caladium Rhizomes need dividing

  • The plant appears crowded and is not producing as many leaves as usual.
  • The leaves are smaller in size compared to previous years.
  • The rhizomes are visibly pushing against the sides of the container or planting area.

Best time of year for dividing Caladium Rhizomes

The best time to divide Caladium rhizomes is in the spring, just before the growing season begins. This allows the newly divided plants to establish themselves and start growing vigorously during the warmer months. It is important to wait until any threat of frost has passed before dividing the rhizomes to ensure they have the best chance of thriving.

Preparing for Rhizome Division

Gathering necessary tools and materials

Before starting the process of propagating your caladium through rhizome division, it is important to gather all the necessary tools and materials. You will need a sharp knife or garden shears, a clean cutting board or surface, a pair of gloves to protect your hands, a container with water for soaking the rhizomes, and some potting soil for replanting.

Pre-dividing preparations

Before actually dividing the rhizomes, there are a few steps you should take to ensure a successful propagation process. Start by choosing a healthy and mature caladium plant with multiple stems and leaves. Water the plant a day before dividing the rhizomes to ensure that the roots are well-hydrated and easier to work with. Additionally, make sure to clean and sterilize your tools to prevent any potential infections or diseases from spreading to the plant.

Steps for Propagating Caladium through Rhizome Division

Step 1: Digging up the Caladium plant

Before starting the division process, carefully dig up the caladium plant from the soil. Use a garden shovel or fork to gently loosen the soil around the plant to avoid damaging the rhizomes.

Step 2: Dividing the rhizomes

Once the caladium plant is out of the ground, carefully separate the rhizomes from the main plant. Look for sections of the rhizomes that have at least one eye or bud, as these are the parts that will grow into new plants. Use a sharp, clean knife to cut the rhizomes into sections, making sure each section has a healthy eye.

Step 3: Replanting the divisions

After dividing the rhizomes, it’s time to replant them in a suitable location. Choose a well-draining soil mix and plant the rhizome sections with the eyes facing upwards. Cover them with a thin layer of soil and water thoroughly to help them establish in their new environment.

By following these steps, you can successfully propagate caladium plants through rhizome division and enjoy a beautiful garden filled with these colorful and tropical plants.

Caring for Divided Caladium Rhizomes

Post-division care tips

After dividing your Caladium rhizomes, it is important to provide them with the proper care to ensure their health and growth. Here are some post-division care tips to follow:

  • Keep them in a warm, humid environment: Caladiums thrive in warm and humid conditions, so make sure to place your divided rhizomes in a location with adequate warmth and humidity.

  • Avoid direct sunlight: Direct sunlight can damage the delicate rhizomes, so it is best to keep them in a shaded area where they can still receive indirect sunlight.

  • Monitor for pests and diseases: Keep a close eye on your divided Caladium rhizomes for any signs of pests or diseases, such as yellowing leaves or holes in the foliage. Treat any issues promptly to prevent them from spreading.

Watering and fertilizing divided Caladiums

Proper watering and fertilizing are essential for the health and growth of divided Caladium rhizomes. Here are some tips to ensure they are well-nourished:

  • Watering: Caladiums prefer consistently moist soil, so make sure to water them regularly to keep the soil evenly moist. Avoid overwatering, as this can lead to root rot.

  • Fertilizing: Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium to provide your divided Caladium rhizomes with the nutrients they need to thrive. Fertilize every 4-6 weeks during the growing season, following the instructions on the fertilizer package.

    Troubleshooting Common Issues

Signs of stress in divided Caladiums

  • Wilting leaves: If you notice your divided Caladiums’ leaves are wilting or drooping, it could be a sign of stress. This could be due to inadequate watering, improper lighting, or shock from the division process.
  • Yellowing leaves: Yellow leaves on your divided Caladiums may indicate overwatering or nutrient deficiencies. Make sure to adjust your watering schedule and provide the necessary nutrients to help them recover.
  • Stunted growth: If your divided Caladiums are not growing as expected, it could be a sign of stress. Check for proper soil drainage, light exposure, and temperature to ensure they are in optimal conditions for growth.

Dealing with rot or disease

  • Preventative measures: To avoid rot or disease in your divided Caladiums, make sure to plant them in well-draining soil and avoid overwatering. Proper air circulation and spacing between plants can also help prevent the spread of disease.
  • Treatment options: If you notice signs of rot or disease in your divided Caladiums, such as dark spots on leaves or mushy stems, you may need to take action. Remove any affected parts of the plant, improve drainage, and consider using fungicides or other treatments recommended for the specific disease. Consult with a plant specialist if needed for further assistance.


In conclusion, propagating caladium through rhizome division is a simple and effective way to expand your collection of these beautiful plants. By following the top tips outlined in this article, such as choosing healthy rhizomes, using sharp tools, and providing proper care after division, you can successfully propagate your caladiums and enjoy a flourishing garden filled with these stunning foliage plants. Remember to be patient and attentive to the needs of your caladiums, and you will be rewarded with vibrant and thriving plants for years to come.
