Growing new roots from plant clippings, also known as propagation, is a rewarding process that allows you to create new plants from existing ones. Here's a step-by-step guide:
1. Preparation is Key:
- Sanitize your tools: Clean your cutting tools (scissors, pruning shears, or knife) with rubbing alcohol to prevent the spread of diseases.
- Prepare your rooting medium: You can use several options:
- Potting mix: A well-draining potting mix is a good choice.
- Perlite or Vermiculite: These provide excellent aeration and drainage.
- Water: Some plants root easily in water.
- Choose your container: Select a clean pot or container with drainage holes. If rooting in water, a clean jar or glass works well.
2. Taking the Cutting:
- Select a healthy stem: Choose a healthy, non-flowering stem from the parent plant. Avoid stems that are too woody or too soft and succulent.
- Make the cut: Use your sanitized cutting tool to make a clean cut just below a node (the point where a leaf or bud emerges from the stem). The length of the cutting typically ranges from 3-6 inches, depending on the plant species.
- Remove lower leaves: Strip off the leaves from the bottom one-third to one-half of the cutting. This prevents them from rotting and encourages root formation.
3. Encouraging Root Growth:
- Wound the end (Optional): Gently scrape or wound one or two sides of the bottom inch of the cutting. This can encourage root formation, particularly for more difficult-to-root species.
- Apply rooting hormone (Optional): Dip the cut end of the stem into rooting hormone powder or liquid. Rooting hormone contains auxins, which stimulate root development. This is particularly helpful for plants that are slow to root. Be sure to follow the product instructions.
- Skip rooting hormone some plants like Pothos, Geranium, Begonia, or African Violet root readily without any hormone.
4. Planting and Care:
- Insert the cutting into the rooting medium: Make a hole in the rooting medium with a pencil or stick, and gently insert the cut end of the stem. Avoid damaging the stem. Ensure that at least one node is buried.
- Water thoroughly: Moisten the rooting medium thoroughly, but avoid overwatering, which can lead to rot.
- Provide humidity: Cover the cutting with a plastic bag or place it in a humidity dome to create a humid environment. This helps prevent the cutting from drying out before roots develop. Make sure to vent the bag periodically to prevent mold growth.
- Provide indirect light: Place the cutting in a location with bright, indirect light. Avoid direct sunlight, which can scorch the leaves.
- Be patient: Rooting can take anywhere from a few weeks to a few months, depending on the plant species and environmental conditions.
5. Checking for Roots:
- Gently tug the cutting: After a few weeks, gently tug on the cutting. If you feel resistance, it means roots have formed.
- Look for new growth: New leaf growth is also a sign that roots have developed.
6. Transplanting (if applicable):
- Once the roots are well-established: If you started the cutting in water or a small container, carefully transplant it into a larger pot with potting mix.
