Plant  Propagation: Calathea

Plant Propagation: Calathea

Calathea plants are typically propagated through division, a process that involves separating the plant into smaller sections, each with its own roots and stems. Here's a step-by-step guide on how to propagate Calathea through division:

Calathea Propagation by Division:

1. Choose a Healthy Plant:

  • Select a mature and healthy Calathea plant for propagation. It's best to perform division during the growing season (spring or early summer).

2. Gather Supplies:

  • Sharp, clean pruning shears or a knife.
  • Small pots with fresh potting mix.
  • Watering can.

3. Water the Plant:

  • Water the Calathea thoroughly a day or two before propagation. Moist soil makes the division process easier.

4. Prepare the New Containers:

  • Fill small pots with a well-draining potting mix. Make a hole in the center to accommodate the roots of the divided sections.

5. Remove the Plant from the Pot:

  • Gently remove the Calathea from its pot. If the roots are tightly bound, you may need to tap the bottom and sides of the pot to loosen the root ball.

6. Identify Natural Divisions:

  • Look for natural divisions or "clumps" in the plant, where there are multiple stems emerging from the base. Each clump can be separated into an individual plant.

7. Division:

  • Use sharp pruning shears or a knife to carefully divide the plant into smaller sections, ensuring that each section has roots attached. Try to keep the divisions intact with their own stems and roots.

8. Trim Roots and Foliage:

  • Trim any damaged or excessively long roots. Also, trim a portion of the foliage to reduce stress on the newly divided plants. Aim for a balance between the roots and foliage.

9. Plant the Divisions:

  • Place each division into a prepared pot, pressing the potting mix gently around the roots. Water the newly potted divisions.

10. Provide Care:

  • Place the newly potted divisions in a location with bright, indirect light. Maintain a humid environment, especially during the initial weeks after division.

11. Watering:

  • Keep the soil consistently moist but not waterlogged. Mist the foliage regularly to maintain humidity around the plants.

12. Monitor and Adjust:

  • Monitor the newly propagated plants for signs of stress or wilting. Adjust the care routine as needed to ensure the divisions establish themselves.

Tips and Considerations:

  • Propagation is best done when the plant is actively growing.
  • If the plant is too large, you can divide it into more manageable sections.
  • Rooting hormone is generally not necessary for Calathea propagation.
  • Be gentle during the division process to minimize stress on the plant.

By following these steps, you can successfully propagate Calathea plants through division and enjoy new, healthy plants over time.
