It is a dense shrub that grows up to a height of 1.5 meters and resembles a miniature tree. Commonly known as the Alternating-leaf Nechamandra, the plant has many uses in traditional medicine.
Appearance of Nechamandra alternifolia
The shrub has a distinctive appearance and can be readily identified by its thin, leathery leaves. The leaves are arranged alternately on the stem, and each leaf is elliptical with a pointed tip. The plant's stem and branches are purple-brown in color, and the bark is rough to the touch. The plant produces small, fragrant white and pink flowers that are highly attractive to bees and butterflies.
Traditional Uses of Nechamandra alternifolia
The Alternating-leaf Nechamandra has long been used in traditional medicine due to its many curative properties.

The plant's distinctive appearance and fragrant flowers make it a popular addition to gardens and green spaces, while its medicinal properties continue to be studied and explored.
Light Requirements
The plant Nechamandra alternifolia prefers moderate to full sunlight to thrive. However, it grows well in partial shade as well. It is best to avoid direct exposure to strong, intense sunlight, especially during the hot summer months, as it can lead to sun damage or scorching of the leaves.
Temperature Requirements
The plant grows in warm to hot climates and can tolerate temperatures from 20 °C to 32 °C. It prefers a humid atmosphere, making it a popular choice for tropical and subtropical regions. The plant can be damaged by frost or extended exposure to cold winter temperatures below 10°C.
Soil Requirements
Nechamandra alternifolia thrives in well-draining soil, and it prefers soil that is slightly acidic to neutral in pH. It can tolerate a wide range of soils, including sandy and loamy soils, but it may struggle in clay soil. It is essential to keep the soil consistently moist but not waterlogged, as waterlogged roots can quickly lead to root rot and other fungal diseases.
Cultivation Methods
Nechamandra alternifolia can be propagated by seeds, stem cuttings, and division of roots. The most efficient propagation method, however, is through stem cuttings.
The plants need well-draining soil and moderate sunlight exposure. They can grow in full sun or partial shade, but too much shade can cause leggy growth.
Watering Needs
Nechamandra alternifolia prefers consistent moisture but is prone to root rot in waterlogged soils. Water the soil deeply once or twice a week during the growing season and reduce watering during winter dormancy.
Fertilization
Apply a balanced fertilizer during the growing season to encourage healthy growth. Avoid over-fertilizing as it may cause excessive growth and weaken the plant.
Pruning
Prune Nechamandra alternifolia annually to shape the plant and promote fuller growth. Cut off any dead or damaged branches and trim back overgrown stems. Pruning can be done during the active growing season or during winter dormancy.
Propagation of Nechamandra Alternifolia (Roxb.) Thw.
Nechamandra Alternifolia (Roxb.) Thw. is commonly known as the Mohwa tree, which is native to India. Propagation of this plant involves the following methods:
Seed Propagation
The Mohwa tree produces seeds, which can be collected and stored for later use. The seeds should be collected from ripe fruit and dried in the shade. The best time to sow seeds is during the monsoon season. The seeds can be sowed directly in the soil or in seedling trays filled with a well-draining medium. Germination of seeds occurs within a month, and seedlings can be transplanted to their permanent location after they are 1-year-old.
Cuttings Propagation
The Mohwa tree can also be propagated through cuttings. Semi-hardwood cuttings are taken during the monsoon season. The cuttings should be taken from healthy trees and treated with rooting hormone powder. The cuttings are then planted in a well-draining medium and kept in a shaded area. With regular watering, the cuttings will root within a month, and they can be transplanted to their permanent location after six months.
Air-layering Propagation
Air-layering is another method of propagating the Mohwa tree. A healthy branch is selected and a 15cm section of bark is removed from near the base of the branch. Rooting hormone powder is applied to the exposed area, which is then wrapped with moist sphagnum moss and covered in plastic. The moss is kept moist, and after a few months, roots will develop. The rooted branch can then be cut from the parent plant and transplanted to its permanent location.
Disease Management
Nechamandra alternifolia is generally resistant to most diseases. However, it can be susceptible to root rot, which is caused by soil-borne fungi. The most effective way to manage root rot is to prevent it from occurring in the first place by avoiding wet soil conditions.
If root rot is already present, the affected plant parts should be removed and destroyed immediately. In severe cases, the entire plant may have to be removed to prevent further spread of the disease. To prevent the spread of the fungi, the soil should be treated with a fungicide.
Pest Management
Nechamandra alternifolia is also relatively resistant to most common pests. However, it can occasionally fall prey to scale insects and spider mites, which may cause severe damage to the plant.
The best way to manage scale insects and spider mites is to regularly inspect the plant for signs of infestation. If infestation is detected early, the affected plant parts should be removed and destroyed to prevent the spread of the pests. In severe cases, insecticidal soap or horticultural oil may be used to manage the pests.
Avoid over-fertilisation as it may attract pests and cause rapid growth, which can make the plant more susceptible to infestations and diseases.
Maintaining good plant hygiene, such as removing any dead or diseased plant parts, can also help prevent the occurrence of pests and diseases. It is also recommended to avoid overcrowding the plant and to maintain appropriate plant spacing for good air circulation.
