Eradicating Invasive Shasta Daisies: Roundup Spot Treatment or Total Renovation

Two Strategies Based on What Else Is There

If Daisies Are Alone in the Bed

Spray entire area with glyphosate (Roundup). Wait 2 weeks. Replant from scratch.

If Desirable Plants Are Mixed In

1. Wear gloves.
2. Pour Roundup into small container.
3. Paintbrush-apply to each daisy plant's leaves.
4. Repeat as needed.

Organic Alternative (Ladybugs Present)

Dig out identified daisies now. Next spring, spot-treat any returns with Roundup after ladybugs are gone. No chemical-free quick fix for established perennial weeds.

Persistence wins. Daisies spread by rhizomes and seed—remove every piece.
