Propagation: Boerhavia repens L. var. ehrenbergerii Asch. & Graebn. can be propagated from seeds or stem cuttings. During the growing season, the plant produces small white flowers that develop into fruit containing the seeds. Stem cuttings can be taken from mature plants during the growing season and should be planted in a moist potting mixture. The cuttings should be kept warm and moist until they begin to root.
Cultivation
The plant Boerhavia repens L. var. ehrenbergerii Asch. & Graebn. can be grown in a wide range of soil types, but it thrives best in sandy loam soil. It also prefers a warm and humid climate, with temperatures ranging from 20 to 28°C. The plant grows well in full sunlight or partial shade and can be propagated through stem cuttings or seeds.
Watering Needs
Boerhavia repens L. var. ehrenbergerii Asch. & Graebn. requires regular watering to maintain its growth. It is essential to ensure that the soil is moist but not waterlogged, as excessive water can cause root rot and other fungal diseases. The frequency of water application will depend on the climatic conditions and soil type, but it is generally recommended to water the plant once or twice a week.
Fertilization
The plant requires fertilization during the growing season to promote healthy growth and development. It is recommended to use a balanced fertilizer with equal amounts of nitrogen, phosphorous, and potassium.

It is advisable to remove any dead or damaged branches and to cut back the tips of the branches to promote bushy growth.
Propagation Methods of Boerhavia repens L. var. ehrenbergerii Asch. & Graebn.
Boerhavia repens L. var. ehrenbergerii Asch. & Graebn. can be propagated through both sexual and asexual methods.
Sexual Propagation
The plant produces bisexual flowers that can self-pollinate or cross-pollinate with other plants. The resulting seeds can be collected and planted directly in the soil, or they can be first germinated in containers and then transplanted into the ground once they have developed root systems. The ideal time to plant seeds is during the beginning of the rainy season, as this will provide the necessary moisture for the seeds to grow.
Asexual Propagation
Boerhavia repens L. var. ehrenbergerii Asch. & Graebn. can also be propagated through various asexual methods which are:
- Root Cuttings: Cuttings of the plant's roots can be taken and placed in a rooting hormone to encourage growth, and then planted into the soil once they have developed roots.
- Stem Cuttings: Cuttings of the plant's stem can be taken and dipped in a rooting hormone, then placed in a container with potting mix or directly into the soil to root and grow.
- Division: The plant can be divided at the roots into smaller sections, each with a section of the rhizome, and then planted as separate individuals.
These asexual propagation methods are best performed during the rainy season when there is plenty of moisture and the plant is actively growing.
Disease Management
Boerhavia repens L. var. ehrenbergerii Asch. & Graebn. is susceptible to various types of fungal diseases such as leaf spot, powdery mildew, root rot, and leaf blight. To manage these diseases effectively:
- Remove and destroy all the infected plant debris and do not compost them as it may increase the risk of spreading the disease.
- Avoid overhead irrigation and watering the plant excessively as it increases the humidity level that aids in the growth of fungal spores.
- Prune off the diseased leaves or branches and dispose of them properly to prevent the disease from spreading.
- Apply fungicide sprays regularly to prevent the diseases, but use them strictly as per their instructions.
Pest Management
Boerhavia repens L. var. ehrenbergerii Asch. & Graebn. can be attacked by various pests that include spider mites, caterpillars, and aphids. To manage these pests effectively:
- Regularly monitor the plant for pest infestations and identify them accurately to select an appropriate control method for them.
- Remove and destroy severely infected plant parts or sections to control the pest population.
- Use insecticidal soaps or oils or neem oil sprays to manage the pests.
