Furthermore, propagating Christmas cactus allows you to share the joy of this plant with your friends and family. Giving the gift of a propagated Christmas cactus not only spreads holiday cheer but also helps others experience the satisfaction of nurturing a plant from its early stages of growth.
Proper potting and repotting are crucial for the long-term health and vitality of your Calathea plants. By choosing the right potting vessel and repotting at the appropriate time, you can ensure your Calathea plants continue to thrive and display their stunning foliage.
Propagation of Calathea Plants
If you want to expand your collection of Calathea plants or share their beauty with others, you can propagate them through division or by rooting cuttings in water. Here’s how:
Propagation by Division
- Carefully remove the Calathea plant from its pot, gently loosening the roots.
- Inspect the plant and identify healthy sections with their own set of roots.
- Using a clean, sharp knife or scissors, carefully divide the plant into smaller sections, ensuring that each section has its own roots.
- Plant the divided sections into separate pots filled with well-draining soil.
- Water the newly potted sections thoroughly and place them in a location with bright, indirect light.
Propagation by division is an effective method for propagating Calathea plants, as it allows each section to develop its own root system and grow independently.
Propagation in Water
- Take a healthy cutting from a mature Calathea plant, making sure it has a node, which is a small bump on the stem.
- Fill a jar or container with water and place the cutting in it, making sure the node is submerged.
- Keep the jar in a warm and well-lit area, away from direct sunlight.
- Change the water every few days to prevent stagnation and maintain its freshness.
