Light Requirements
Boerhavia repens L. var. diffusa auct. requires full sun exposure for optimal growth and development. It is a highly adaptable plant and can tolerate some shade in the afternoon, but prolonged shade can lead to reduced growth and flowering.
Temperature Requirements
The plant thrives in warm temperatures, ranging from 25°C to 35°C. Temperatures below 15°C can cause damage to the plant and hinder growth. Boerhavia repens L. var. diffusa auct. is a drought-tolerant plant and can survive in hot and dry conditions.
Soil Requirements
The plant prefers well-draining soils with high organic matter content, but it can tolerate a range of soil types, including sandy, loamy, and clay soils. The soil must be slightly acidic with a pH ranging from 6.5 to 7.5. The presence of excess nutrients or salinity can have adverse effects on the growth of Boerhavia repens L. var. diffusa auct.
Cultivation Methods
Boerhavia repens L. var. diffusa auct. or simply Boerhavia repens is a hardy perennial plant that can handle a wide range of soil and climatic conditions. It grows best in sandy or loamy soil that is well-drained and gets plenty of sunlight. It is drought-resistant and can survive in areas with little rainfall, but it grows best with regular watering.
When planting Boerhavia repens, make sure to choose a spot with plenty of sun exposure. If there isn't enough sun, the plant may not grow as well or produce as many flowers. Plant the seeds about 1/4 inch deep in the soil and water the area until the soil is moist but not soggy.
Watering Needs
Boerhavia repens is a hardy plant that can handle periods of drought, but it grows best with regular watering. During periods of low rainfall or high heat, it is essential to keep the soil moist but not overly saturated. Watering should be done at the base of the plant, avoiding getting water on the leaves or flowers as this can lead to disease.
It's critical to pay attention to the soil and adjust your watering schedule based on the moisture content. If the soil is dry to the touch, water the plant. If the soil is still moist, wait a day or two before watering again.
Fertilization
Boerhavia repens doesn't require a lot of fertilizer, but it benefits from feeding during its growing season. Use a balanced fertilizer that has equal parts nitrogen, phosphorus, and potassium, every four to six weeks during the growing season. Be sure to follow the label instructions for application rates.
As the plant matures, use a slow-release fertilizer that will break down as the plant grows. This will provide a steady supply of nutrients without overloading the soil.
Pruning
Boerhavia repens requires minimal pruning, usually just to remove any dead or damaged stems, to promote fuller growth of the plant. Prune the plant during its dormant period in late winter or early spring before new growth appears. Cut back any dead or damaged stems with pruning shears.
If the plant is becoming too large, prune it back to the desired size in late winter or early spring. When pruning, avoid cutting into old wood as this can damage the plant and leave it open to disease.

After a few weeks, the cutting will develop roots and can be transplanted into the garden.
Division Propagation
Another method of propagating Boerhavia repens L. var. diffusa auct. is through division. It involves dividing the rhizomes of a mature plant and planting them in a prepared bed. First, dig out the plant and remove the soil around the rhizome. Gently separate the rhizomes with a knife and plant them in individual holes with the crown just below the soil surface. Water the newly planted divisions thoroughly and keep them moist till they establish themselves.
Boerhavia repens L. var. diffusa auct. can be propagated through seed, cutting or division methods. Choose the method that suits your needs and get started. With proper care, the plant will provide years of beauty and medicinal value to your garden.
