Pruning
Pruning is a crucial part of caring for Justicia plicata Vahl. The plant can get leggy if not pruned regularly, leading to stunted growth and reduced flowering. It is advisable to prune the plant after the blooming period ends and before the onset of the winter season.
To prune, remove any dead, damaged, or diseased parts of the plant with sharp, clean shears. You can also trim the tips of the branches to encourage the plant to produce bushier growth and more flowers. Additionally, prune any branches that are crossing or rubbing against each other, as these can damage the plant in the long run.
Propagation of Justicia plicata Vahl

Propagation Methods of Justicia plicata Vahl
There are several methods of propagating Justicia plicata Vahl:
- Division: This is the most common method of propagation. It involves dividing the root ball of a mature plant into smaller sections and replanting them. This should be done during the plant's dormant period in the spring.
- Cuttings: Stem cuttings can also be used to propagate Justicia plicata Vahl. Take a 4-6 inch cutting from the tip of a stem and place it in a pot with well-draining soil. Keep the soil moist and place the pot in a warm, bright location until the cutting establishes roots and begins to grow.
- Seeds: Justicia plicata Vahl can also be propagated from seeds. The seeds should be sown in a well-draining soil mixture and kept moist and warm until they germinate, which can take up to a month. Once the seedlings have grown a few inches tall, they can be transplanted to larger containers or outdoors.
Regardless of the propagation method used, it is important to keep the newly propagated plants moist and in a warm, bright location until they have established a robust root system and can be transplanted to their permanent location.
