Answer:

Helena Crossbow Herbicide could kill or at least suppress horseradish plants however, it is not labeled specifically for this application. Horseradish can be prolific quite easily, so it is best to dig out the plants each year, being careful to get every possible root you can so that there are no remaining fragments that can grow into new plants. The Crossbow is not safe to use around hibiscus or other desirable ornamental plants, and can last up to 12 months in the soil and inhibit seed germination or plant growth. If you feel like the horseradish has invaded the area badly, then you could transplant the hibiscus but just be aware that you will need to be careful not to take any of the horseradish roots to a new location.
