What To Know
- Plant the cutting in a pot filled with a well-draining potting mix.
- Plant the rhizome sections in a pot filled with a well-draining potting mix.
- While it is possible to root calathea cuttings in water, it is not as successful as propagating in soil.
Calatheas, also known as prayer plants, are beloved for their vibrant foliage and air-purifying abilities. Propagating these plants is a rewarding experience that allows you to expand your collection or share the joy with others. This comprehensive guide will provide you with step-by-step instructions and tips on how to propagate calathea successfully.
Methods of Calathea Propagation
There are several methods to propagate calathea, each with its own advantages and considerations.
Division
Pros:
- Preserves the original plant’s characteristics
- Produces multiple new plants
Cons:
- Requires an established plant with multiple stems
- Can disturb the parent plant
Stem Cuttings
Pros:
- Rapid propagation
- Can produce multiple new plants from a single stem
Cons:
- Requires suitable stems with nodes
- May take longer for the cuttings to develop roots
Rhizome Cuttings
Pros:
- Produces multiple new plants
- Less invasive than division
Cons:
- Only suitable for calathea varieties with rhizomes
- May require specialized tools for cutting
Step-by-Step Propagation Guide
Division
1. Remove the calathea from its pot and gently loosen the soil.
2. Identify the natural divisions between the stems.
3. Carefully separate the stems, ensuring each division has a healthy root system.
4. Repot the separated divisions in individual pots with fresh potting mix.
Stem Cuttings
1. Select a healthy stem with at least one node.
2. Using a sharp knife or scissors, make a clean cut just below a node.
3. Remove the bottom leaves from the cutting.
4. Dip the end of the cutting in rooting hormone (optional).
5. Plant the cutting in a pot filled with a well-draining potting mix.
6. Keep the soil moist and provide indirect light.
Rhizome Cuttings
1. Identify a rhizome (a fleshy, underground stem) that has multiple growth points.
2. Using a sharp knife or pruning shears, cut the rhizome into sections, ensuring each section has at least one growth point.
3. Plant the rhizome sections in a pot filled with a well-draining potting mix.
4. Keep the soil moist and provide indirect light.
Tips for Successful Propagation
- Use sharp and clean tools to prevent disease.
- Provide the cuttings or divisions with adequate moisture and humidity.
- Keep the plants in a warm environment with indirect light.
- Be patient, as propagation can take several weeks or months.
Common Calathea Propagation Problems
Cuttings Failing to Root
- Ensure the cuttings are healthy and have nodes.
- Use rooting hormone to promote root development.
- Keep the soil consistently moist but not waterlogged.
Divisions Not Thriving
- Avoid overwatering the separated divisions.
- Provide them with a well-draining potting mix.
- Keep the plants in a warm and humid environment.
Rhizome Cuttings Rotting
- Ensure the rhizome sections are healthy and free of disease.
- Plant the cuttings in well-draining soil.
- Avoid overwatering and provide adequate drainage.
Final Thoughts: The Joy of Calathea Propagation
Propagating calathea is a fulfilling endeavor that allows you to multiply your collection of these beautiful plants. By following the methods and tips outlined in this guide, you can confidently embark on this rewarding journey. Remember to be patient and provide your cuttings or divisions with the necessary care to ensure their success.
Frequently Asked Questions
Q: How long does it take to propagate calathea by division?
A: It can take several weeks to months for the separated divisions to establish a strong root system.
Q: Can I propagate calathea in water?
A: While it is possible to root calathea cuttings in water, it is not as successful as propagating in soil.
Q: How do I know when my calathea cuttings have rooted?
A: Gently tug on the cutting. If it resists, it has likely developed roots.
