Light Requirements
This plant thrives in full sunlight and requires at least 6 hours of direct sunlight every day.
Temperature Requirements
Sphaeranthus hirtus auct. prefers warm to hot temperatures and grows best when the temperature is between 20°C to 35°C.
Soil Requirements
The plant grows well in well-draining, sandy or loamy soils rich in organic matter. The pH of the soil should be slightly alkaline to neutral, around 7 to 8.5. However, this plant can also tolerate slightly acidic soils with a pH of 6 to 7.
It is important to note that this plant cannot grow in waterlogged soils, as it requires good drainage to flourish.
Cultivation methods
Sphaeranthus hirtus auct. is a perennial plant that can grow up to 50-70 cm in height. This plant thrives well in a sunny location with well-draining soil. It is also a drought-tolerant plant, which can withstand prolonged periods of dry weather. When planting, ensure that the soil is loosened, and the debris is removed to avoid competition with the seedlings. The best time to propagate Sphaeranthus hirtus auct. is during the wet season.
Watering needs
Sphaeranthus hirtus auct. requires moderate watering during the growth period, usually from spring to fall. The soil should be moist but not too wet, as it can cause root rot. Watering should be reduced during the winter period when the plant is dormant.
Fertilization
It is recommended to fertilize Sphaeranthus hirtus auct. once every two weeks during the growing period. The use of a balanced fertilizer that contains nitrogen, phosphorus, and potassium is ideal. However, reduced fertilization during the winter period is recommended.
Pruning
Sphaeranthus hirtus auct. requires minimal pruning, especially during the first year of growth. Pruning can be done to remove dead or diseased stems whenever it is noticed. It is important to avoid pruning the plant during the winter period as it may weaken the plant.
Propagation of Sphaeranthus Hirtus Auct.
Sphaeranthus hirtus auct., a medicinal plant also known as East Indian globe thistle, is propagated through seedlings, stem cuttings, and root cuttings. The ideal season for propagation is in the spring or early summer.
Seed Propagation
Seeds of Sphaeranthus hirtus auct. should be collected from the ripe fruit, cleaned, and sown in well-draining soil. They should be covered with a thin layer of soil and kept moist with regular watering. The germination process may take up to four weeks. Once the seedlings have developed, they can be transplanted to larger pots with potting soil and grown indoors.
Stem Cutting Propagation
Stem cuttings of Sphaeranthus hirtus auct. should be taken from healthy, disease-free plants and stripped of their lower leaves. The cuttings should be treated with rooting hormone and then planted in well-draining soil. The soil should be kept moist until roots have developed and the cuttings have established themselves. This propagation method can produce results within a few weeks.
Root Cutting Propagation
To propagate through root cuttings, healthy plants should be dug up and the roots cut into small pieces. These pieces should be planted in well-draining soil and kept moist until they have established themselves. Although this method can take longer to produce results than stem cutting propagation, it is a reliable method of propagation for Sphaeranthus hirtus auct.
