Rhizome division is the easiest and most reliable way to propagate Wild Ginger (Asarum canadense). This method replicates the plant’s natural growth habit and ensures faster establishment compared to seeds.
When to divide rhizomes:
Early spring (just as growth resumes) or early fall (after the heat has passed but before frost).
These times allow the plant to establish roots before extreme weather.
How to divide Wild Ginger rhizomes:
Choose a healthy clump — Look for dense patches with vigorous growth.
Gently dig up the clump, using a trowel or garden fork. Try to keep root damage minimal.
Rinse or brush off soil so you can see the rhizomes clearly.
Cut or break the rhizomes into sections:
Each piece should be 2–4 inches long
Must have at least one growing point (a shoot or bud)
Replant immediately:
Space divisions 6–12 inches apart
Plant just below the soil surface in moist, rich, well-drained soil
Water well after planting to help establish roots
Aftercare:
Keep soil evenly moist (but not soggy) for several weeks after planting.
Mulch lightly with shredded leaves or bark to retain moisture and mimic forest floor conditions.
Plants will gradually spread to form a lush groundcover.
