Care for Propagated Bougainvillea Plants
After propagating your bougainvillea plants, it’s essential to provide them with proper care to ensure their health and growth:
- Water: Water the plants regularly, allowing the soil to dry out slightly between waterings.
- Fertilizer: Fertilize the plants monthly with a balanced fertilizer.
- Sunlight: Bougainvillea plants need plenty of sunlight to thrive. Place them in a location that receives at least 6 hours of direct sunlight per day.
- Pruning: Prune the plants regularly to encourage new growth and flowering.
Troubleshooting Common Propagation Problems
- Cuttings Not Rooting: Ensure the cuttings are healthy and have been treated with rooting hormone. Check the soil moisture and ensure it’s not too wet or too dry.
- Seedlings Not Germinating: Ensure the seeds are fresh and have been sown at the correct temperature. Provide the seedlings with plenty of light and moisture.
- Layering Not Successful: Make sure the stem is healthy and has been cut properly. Ensure the cut portion is buried in the soil and kept moist.
Harvesting Bougainvillea Bracts
Once your bougainvillea plants have matured, you can harvest the vibrant bracts for use in arrangements or decorations:
- Harvest Time: When the bracts are fully developed and have reached their desired color.
- Harvest Method: Cut the bracts from the plant with a sharp knife or scissors.
