Use Weed B Gon only on the intended turf areas. Never use it on flowers, ornamental plants or in the garden, as the product label warns. The Weed B Gon formula kills several flowering plants.
While Weed B Gon is not intended for use on flowers, the Scotts Miracle-Gro brand suggests covering soil near flowering plants with Nature Scapes mulch and treating flowers every three months with Miracle-Gro Garden Shake'n Feed Plus Weed Preventer.
Weed B Gone and Weed Preventer differ in their primary active ingredients. Weed B Gone features dimethylamine salt as the primary active ingredient. Trifluralin is the primary active ingredient in Miracle-Gro Shake'n Feed Plus Garden Weed Preventer.
