To propagate coleus, take a stem cutting around 4-6 inches long from a healthy plant, remove the lower leaves, dip the cut end in rooting hormone (optional), and plant it in a pot with moist potting mix; you can also root coleus cuttings in a glass of water by placing them in bright, indirect light and changing the water regularly until roots develop, then plant them in soil.
Key steps:
Choose a healthy plant: Select a healthy coleus plant with vibrant foliage.
Take a cutting: Use sharp scissors or pruners to cut a stem about 4-6 inches long, just below a leaf node.
Remove lower leaves: Remove the bottom leaves from the cutting, leaving a few leaves at the top.
Optional: Use rooting hormone: Dip the cut end of the stem in rooting hormone to encourage root development.
Planting in soil: Prepare a pot with a well-draining potting mix.
Make a small hole in the soil and insert the cutting. Firm the soil around the base of the cutting. Water gently and place the pot in bright, indirect light.
Propagating in water: Place the cutting in a glass of fresh water.
Change the water every few days. Once roots develop, plant the cutting in potting mix.
Important points to remember:
Timing: Coleus can be propagated throughout the growing season, but spring and early summer are ideal.
Light conditions: Keep your propagated coleus in bright, indirect light.
Moisture level: Maintain consistent moisture by watering regularly, but avoid overwatering.
Temperature: Ideal rooting temperature is around 60-75°F.
