The plant grows well in well-draining soil that is rich in organic matter. It is essential to ensure that the soil is moist at all times but not waterlogged, as this may cause the roots to rot.
The plant can be propagated by seeds or cuttings. When propagating through cuttings, it is advisable to use mature branches and to dip the cuttings in rooting hormone before planting them in a potting mix.
Watering Needs
Pavetta megistocalyx K.Krause requires frequent watering, especially during the hot season. It is recommended to water the plant once a week or whenever the soil feels dry.
It is essential to ensure that the plant is not overwatered, as this may lead to root rot. The plant prefers moist soil but not waterlogged soil.

Propagation of Pavetta megistocalyx K.Krause
Pavetta megistocalyx K.Krause can be propagated by several methods, including seeds, cuttings, and layering. The following are the detailed propagation methods for this plant:
Propagation by seeds
The seeds of Pavetta megistocalyx K.Krause can be collected from the mature fruit capsules after they have turned brown. These tiny seeds can be sown in a well-draining soil mix that has been moistened. It is essential to plant the seeds at about one centimeter deep and to keep the soil consistently moist. The germination process usually takes around two to three weeks. After the seedlings have established and have grown enough leaves, they can be transplanted to larger pots or containers.
Propagation by cuttings
The best time to take cuttings of Pavetta megistocalyx K.Krause is in the spring or early summer when the plant is actively growing. Take a stem cutting about 10 to 15 centimeters long and remove the leaves from the lower two-thirds of the cutting. Dip the cutting into rooting hormone powder and plant it in a well-draining soil mix. Keep the soil moist and place the cutting in a warm, humid place with bright, indirect light. The roots usually form within six to eight weeks, and after that, it can be transplanted to a larger pot or garden bed.
Propagation by layering
Layering is a reliable propagation method for Pavetta megistocalyx K.Krause, especially when the plant has become too tall or leggy. Choose a low-hanging stem that touches the ground, or you can bend a flexible stem to the ground by using a U-shaped stake to pin it down. Make a slight wound on the stem's bark where it touches the ground and dust it with rooting hormone. Cover the wounded area of the stem with soil, and keep it moist. After a few weeks, roots will start to form, and when they appear, the new plant can be separated from the parent and transplanted to a larger pot or garden bed.
