Managing Chickweed in a New Wildflower Seeding

Managing Chickweed in a New Wildflower Seeding

A Kansas gardener seeded a large bank with wildflowers last fall. In spring, a purple-flowered plant they call chickweed covers the area. Wildflower seeds haven't germinated yet. They ask for a safe herbicide or if they must start over.

Identification First

True chickweed (Stellaria media) has small white flowers, is a shallow-rooted annual, and pulls easily. Purple flowers suggest a different weed (e.g., henbit, purple deadnettle). Take a sample to the local Cooperative Extension office for accurate ID.

Management Options

• Hand-pulling: Best for annuals before seed set; minimal disturbance to wildflower seeds.
• No selective herbicide: Most broadleaf herbicides will kill desirable wildflowers.
• Mowing: If weeds are tall, mow high to prevent shading wildflower seedlings.

Re-seeding Consideration

If the weed is a perennial with deep roots, starting over with proper site preparation (repeated tilling, solarization) may be necessary. But identify the weed first.
