Propagation of Acalypha angustata Sond. var. glabra Sond. is through stem cuttings or seeds. For stem cuttings, take healthy stems of about 4-6 inches long, remove the leaves from the bottom, dip them in rooting hormone, and plant them in a soil mix. For seeds, sow them in pots or trays and keep them moist until germination.
Watering Needs
Acalypha angustata Sond. var. glabra Sond. requires frequent watering, especially during the growing season. Water the plant when the top two inches of soil feel dry to touch. Be careful not to overwater the plant, as this can lead to root rot.
The plant may require less water during the winter months, but ensure the soil stays moist. Water the soil and not the leaves to prevent fungal diseases.
Fertilization
Fertilize Acalypha angustata Sond. var. glabra Sond. during the growing season to promote healthy growth and abundant flowering. Use a balanced liquid fertilizer or a slow-release granular fertilizer applied to the soil.
Follow the manufacturer's instructions for application rates and frequency. Avoid overfertilizing, as this can lead to burnt leaves and root damage.
Pruning
Pruning is important in maintaining the shape and size of Acalypha angustata Sond. var. glabra Sond. Prune the plant in the late winter or early spring before new growth appears.
Remove any dead, damaged, or diseased branches. Pinch the tips of the stems to encourage branching and fuller growth. Cut back any leggy or overgrown branches to promote a bushy growth habit.

- Scarify the seeds with sandpaper to break the seed coat to encourage germination.
- Soak the seeds in warm water for about an hour.
- Sow the seeds in moist soil in seed trays or pots.
- Cover the pot with clear plastic to maintain moisture and place it in a warm and bright area, but out of direct sunlight.
- Keep the soil moist and remove the plastic cover once seedlings appear.
- Once the seedlings are about 2-3 inches tall, they can be transplanted to their permanent location.
Disease and Pest Management for Acalypha Angustata Sond. var. Glabra Sond.
Acalypha angustata Sond. var. glabra Sond. is a beautiful plant that can bring life to any garden. However, it is necessary to take measures to protect it from diseases and pests that may attack it, so it can thrive and maintain its beauty. Below are some of the common diseases and pests that might affect the plant and ways to manage them.
Diseases
Acalypha angustata Sond. var. glabra Sond. is susceptible to various fungal diseases, such as leaf spot, powdery mildew, and rust. Among these diseases, powdery mildew is the most common type that infects this plant. This disease is usually characterized by a white or grayish powdery coating on the leaves, shoots, and flowers. In severe cases, it can cause the leaves and shoots to distort and die.
To manage powdery mildew, you can remove and destroy the infected parts of the plant immediately. Spray the plant with a fungicide that contains potassium bicarbonate, neem oil, or sulfur. Maintain good air circulation around the plant by pruning regularly, and avoid overhead watering, which can increase humidity around the plant.
Pests
Acalypha angustata Sond. var. glabra Sond. is also susceptible to pests, such as spider mites, aphids, and thrips. Spider mites are small arachnids that suck sap from the plant, causing the leaves to turn yellowish and develop a mottled appearance. Aphids are small insects that can be found on the underside of the leaves, and they suck sap from the plant, causing leaf curling and deformation. Thrips are tiny insects that feed on the flowers and leaves, causing discoloration and deformation.
You can manage these pests by spraying the plant with insecticidal soap or neem oil. If the infestation is severe, you may need to use an insecticide that contains pyrethrins. Regularly inspect the plant for signs of infestation, and remove and destroy any severely affected parts of the plant to prevent the spread of the pests.
Implementing these disease and pest management practices can help to protect your Acalypha angustata Sond. var. glabra Sond. and promote its healthy growth.
