Sida Rhombifolia Information

Sida rhombifolia, popular as rhombus-leaved sida or arrow-leaf sida, is a flowering plant in the mallow family, Malvaceae. It is native to tropical and subtropical regions of the Americas, including the Caribbean, Mexico, and Central and South America. Sida rhombifolia is most common along roadsides and in abandoned fields.

Sida rhombifolia is famous for its medicinal properties and people use it for centuries to treat a variety of ailments. It is popular as a diuretic, to reduce inflammation and reduce fever. People also use it to treat skin conditions, such as eczema and psoriasis, and gastrointestinal disorders.

How to Grow Sida Rhombifolia?


Sida rhombifolia is relatively easy to grow from seeds. 

  • Sida rhombifolia seeds can be obtained from seed suppliers or collected from mature plants.
  • The plant prefers well-draining soils. Mix equal parts of sand, loam, and peat moss to create a well-draining soil mix.
  • Sow the seeds directly into the soil or start the seeds in seed trays or pots. Cover the seeds with a thin layer of soil and gently press down to ensure good seed-to-soil contact. If using seed trays or pots, fill them with the soil mix, moisten them, and sow one to two seeds per pot or cell.
  • The seeds require moist soil for germination. Water the seeds gently and consistently to keep the soil moist but not waterlogged. Avoid overwatering, as this can lead to rot.
  • The seeds need warm temperatures to germinate, so keep the soil temperature between 20-30°C (68-86°F).
  • The seeds will germinate in about 3-4 weeks.

Requirements to Grow Sida Rhombifolia

It requires full sun for optimal growth and flowering, but can also tolerate partial shade. As it generally grows alongside roads, Sida rhombifolia thrives when it receives a minimum of 5-6 hours of direct sunlight every day.


Sida Rhombifolia grows best in well-draining soil that is rich in organic matter. A soil mix with equal parts of sand, loam, and peat moss is ideal. The pH of the soil should be between 6.0-7.5.

However, the plant won’t mind growing in any type of soil as it is quite robust.


It is a drought-tolerant plant that does not require much water. It does best in well-drained soils that are kept evenly moist, but not soggy. Water thoroughly when the top 2-3 inches (5-8 cm) of soil is dry. In the hottest months of summer, water more frequently to keep the soil from drying out.


Sida rhombifolia is a tropical plant and requires temperatures between 65°F (18°C) and 85°F (29°C). It can survive temperatures as low as 40°F (4°C) for short periods of time, but prolonged exposure to temperatures below this can damage or even kill the plant.

Sida Rhombifolia Care



As such, it does not require much fertilizer. Sida rhombifolia will benefit from an occasional application of a balanced fertilizer such as a 10-10-10 or a 20-20-20.

However, if the soil is very poor, a nitrogen-only fertilizer can be used to boost growth. When applying fertilizer, it is important to follow the instructions on the package and to avoid applying too much, as this can burn the plant.


Sida Rhombifolia does not require regular pruning. However, removing dead or damaged leaves can improve the appearance of the plant. Prune the plants in late winter or early spring to promote new growth.

Pests and Diseases

It is generally resistant to pests and diseases. However, it can be susceptible to aphids, spider mites, and whiteflies. Regular monitoring and early detection can help prevent infestations.

The plant may be vulnerable to fungal diseases such as root rot and leaf spot in humid conditions. Avoid overwatering and ensure good air circulation to prevent fungal infections.
