Bougainvillea can be cut and replanted through a propagation method known as taking cuttings. This is a common and effective way to propagate bougainvillea and create new plants.
To start, it is best to take cuttings in the spring when the plant is actively growing. Select healthy, non-flowering shoots that are about 6 inches long. It is important to use clean and sharp pruning shears to make a clean cut just below a leaf node.
Once you have your cuttings, it can be beneficial to use hormone rooting powder, if available. This powder contains growth hormones that help stimulate root development. Simply dip the cut end of each cutting into the rooting powder, tapping off any excess.
Next, prepare a suitable planting mix for the cuttings. A mix of equal parts soil and perlite is commonly used, as it provides good drainage and aeration for root development. If you prefer, you can also use a pre-made potting mix that contains perlite.
Before inserting the cuttings into the planting mix, make sure it is moistened to provide a conducive environment for root growth. You can water the mix lightly and allow it to drain before proceeding.
Using your finger or a dibber, create a hole in the planting mix for each cutting. Insert the cut end of the cutting into the hole, ensuring that at least one or two leaf nodes are buried in the mix. Gently firm the mix around the cutting to provide stability.
After planting the cuttings, it is important to create a suitable environment to encourage root development. Place the potted cuttings in a warm and bright location, but avoid direct sunlight as it can be too harsh for newly planted cuttings. You can cover the pot with a clear plastic bag or use a propagator to create a humid microclimate around the cuttings.
Maintain the moisture level in the planting mix by misting it regularly or using a spray bottle to water lightly. It is important to keep the mix consistently moist but not waterlogged, as excess moisture can lead to rotting.
In about 4-6 weeks, you should start seeing signs of root development, such as new growth or resistance when gently tugging on the cutting. Once the cuttings have established a good root system, they can be gradually acclimatized to their final growing conditions by gradually exposing them to more light and reducing humidity.
At this point, you can transplant the rooted cuttings into individual pots or directly into the ground, depending on your preference and the size of the plants. Ensure that the planting location provides full sun, well-draining soil, and enough space for the bougainvillea to grow.
Taking cuttings and replanting bougainvillea can be a rewarding and cost-effective way to propagate and expand your collection. It allows you to create new plants that are genetically identical to the parent plant, ensuring that you can enjoy the same vibrant and colorful blooms.
