Darrell from Hickory, Nc writes
The Killzall Weed and Grass Killer is just like roundup and hence its name, will kill all vegetation you spray it on. You could use the Killzall to spot treat the weeds you see coming up or if the weeds are grassy and not broadleaf weeds you could use a product like Fertilome Over the Top to spray overthe juniper and only kill the grasses. You can also use a pre-emergent product in the spring and fall of each year to help prevent grassy and broadleaf weeds from coming up throughout the growing season. Surflan Pro and Snapshot are two examples of great ornamental planting pre emergent products.
