To propagate a hardy violet, the most common method is division of the plant in early spring, where you carefully separate established clumps of the plant, ensuring each new division has roots attached, and then replant them individually; you can also try propagating from leaf cuttings taken during the growing season, rooting them in a moist, well-draining potting mix with indirect sunlight and high humidity conditions. 

Key steps for propagating hardy violets:

Timing: Early spring is the best time to divide a hardy violet plant. 

Division method: Gently dig up the plant from the soil. 

Identify natural divisions or sections in the root ball.  Use your hands or a sharp knife to carefully separate the plant into individual clumps, making sure each section has roots.  Plant each division in a new location with fresh potting mix. 

Leaf cutting method: Select healthy leaves from the plant. 

Use clean, sharp scissors to take a cutting, including a short stem (petiole).  Remove any lower leaves to prevent rot.  Plant the cutting in a pot filled with a well-draining potting mix.  Keep the soil moist and provide high humidity conditions (e.g., cover with a plastic bag).  Place the pot in a location with bright, indirect sunlight. 

Important considerations:

  • Soil: Use a well-draining potting mix with good organic matter.
  • Watering: Keep the soil moist but not soggy.
  • Light: Provide indirect sunlight for best root development.
  • Humidity: Maintaining high humidity can help the cuttings root successfully.
