To propagate pesto perpetuo basil, you have two options: potting it up in the fall or starting anew from stem cuttings. Both methods are fairly simple and can be successful with the right care.
Potting up in the fall is a great option if you already have an established plant that you want to continue growing. This method allows the plant to continue growing throughout the winter months indoors. It’s best to bring the plant inside early, in September or even late August, as pesto perpetuo basil is a subtropical plant that dislikes cold temperatures. By bringing it in early, you can ensure that the plant roots and grows better in a warm environment.
When potting up, choose a container that is large enough to accommodate the plant’s root system. Fill the pot with a well-draining potting mix and gently transfer the plant into the new container. Be careful not to damage the roots during this process. Place the pot in a location that receives bright, indirect light and maintain a warm and humid environment. Water the plant regularly, but avoid overwatering as it can lead to root rot.
If you prefer to start anew from stem cuttings, this method is also quite effective. Begin by selecting a healthy stem from the parent plant. Using clean and sharp scissors or shears, cut a 4-6 inch section of the stem just below a leaf node. Remove the lower leaves from the cutting, leaving a few leaves at the top intact.
Next, prepare a small container with a well-draining potting mix. Moisten the soil slightly to ensure it is damp but not waterlogged. Dip the cut end of the stem in a rooting hormone powder to encourage root development. Insert the cutting into the potting mix, making sure the node is covered with soil and the leaves are above the surface.
To create a warm and humid environment for the cutting, you can cover the container with a clear plastic bag or place it in a propagator. Mist the cutting and the inside of the bag regularly to maintain humidity. Place the container in a location with bright, indirect light, but avoid direct sunlight as it can scorch the cutting.
Over the next few weeks, the cutting should develop roots. You can gently tug on the cutting to check for resistance, indicating that roots have formed. Once the cutting has established roots, you can transplant it into a larger pot or into your garden.
Remember to provide the newly potted basil plant or the rooted cutting with proper care, including regular watering, adequate light, and a warm environment. With these steps, you can successfully propagate pesto perpetuo basil and enjoy its flavorful leaves for months to come.
