Yes, Snapshot DG Herbicide is labeled for pre emergent control of clover in landscape beds, ornamentals, bushes, trees, shrubs, etc.
Please refer to the full product label for more information.
Snapshot DG Herbicide is not labeled for use on turfgrass at all and would not be safe to apply. Ferti-lome with Gallery would be a better option depending on the target weeds. Anything with Dithiopyr is also great to use in the spring and there are granule options.
