Sinapis torosa Plant Care

Sinapis torosa (Sinapis torosa) belongs to the Brassicaceae family within the Sinapis genus. Sinapis torosa is native to the fields of North Africa, Asia, Europe, and some other areas.

Sinapis torosa displays an upright, branching herb growth habit, reaching up to 2 ft tall with a spread of approximately 1.5 ft. Sinapis torosa produces small yellow flowers in clusters.

Leaf size: approximately 4 inches.

Sinapis torosa requires watering every 4–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Sinapis torosa thrives in full sun to partial shade.

Sinapis torosa grows best at temperatures of 50–75°F. Sinapis torosa prefers humidity levels of 40–60%.

Well-draining loamy soil rich in organic matter. Good drainage is essential for Sinapis torosa to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sinapis torosa every 3 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

Annually in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
