Casoron 4G Herbicide is not labeled to be used around bulb plantings, so we would not recommend this application. Gallery 75 DF can be used around ornamental bulb plantings 2-4 weeks after planting but prior to emergence of annual weeds. Per the product label: Gallery also may be applied following bulb emergence but prior to flowering and after flowering. For fall planted bulbs, apply Gallery 75 DF in late winter or early spring to weed-free soil surfaces. For bulbs, make a single applcation wtithin 30 days following planting and prior to bulb emergence.
