Rough-toothed Horsetail Plant Care

Rough-toothed Horsetail (Equisetum trachyodon) belongs to the Equisetaceae family within the Equisetum genus. Rough-toothed Horsetail is native to northwestern and central Europe.

Rough-toothed Horsetail displays an upright, bushy growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Rough-toothed Horsetail produces non-flowering.

Leaf size: approximately 12 inches.

Equisetum trachyodon requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Rough-toothed Horsetail thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Rough-toothed Horsetail in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Equisetum trachyodon grows best at temperatures of 50–75°F. Rough-toothed Horsetail prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Moist, sandy soil with good drainage. Good drainage is essential for Rough-toothed Horsetail to prevent waterlogging, which leads to root rot and fungal issues.

Feed Rough-toothed Horsetail every 6 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.

Repot every 1-2 years. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
