Andersons 0.48 Barricade Herbicide is not labeled to be used around tulips ornamental bulbs. We would recommend Snapshot 2.5 TG Granules for pre-emergent control around flowering plants and ornamentals. Applications should be made 2-4 weeks before weed emergence for best results.
Snapshot 2.5 TG Granules can also be applied following bulb emergence but before flowering after flowring. For fall planting bulbs, applications should be made in late winter and early spring.
