What Is the Torpedograss?
Torpedograss (Panicum repens) belongs to the Poaceae family within the Panicum genus. Torpedograss is native to "Africa and/or Asia", "Europe or Australia", "Eurasia", "Australia", "Europe, Asia, and Africa", or other specific regions, including the Mediterranean, and Argentina. Torpedograss is also known as Dollar Panicgrass.
Torpedograss displays a tall, upright grass growth habit, reaching up to 6 ft tall with a spread of approximately 2 ft. Torpedograss produces feathery panicles of tiny flowers.
Leaf size: approximately 12 inches.
How Often Should You Water a Torpedograss?
Panicum repens requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

What Soil Mix Works Best for a Torpedograss?
Well-draining loamy soil with good fertility. Good drainage is essential for Torpedograss to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Torpedograss?
Feed Torpedograss every 8 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.
Fertilizing
Every 8 months
During the growing season
The PlantoScan app can remind you when to water and when to fertilize each plant.
How Do You Repot a Torpedograss?
Divide clumps every 2-3 years 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.
How Do You Propagate a Torpedograss?
Torpedograss can be propagated through seeds. Similar propagation techniques also apply to panicum lycopodioides plant care, which shares the same genus.
Is the Torpedograss Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Torpedograss, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.
