Unfortunately, the extent of injury to the Royal Purple Liriope and soil is going to be difficult to determine. With the product label precautions and advising to be cautious of wind drift, preventing overspray and to avoid spraying desirable plants with Helena Crossbow Herbicide, it is really a wait and see. The product label states, excessive amounts of this herbicide in the soil may temporarily inhibit seed germination and plant growth. The residual of Crossbow Herbicide in the soil can remain for up to 1 year therefore it is recommended to wait 1 year after an application to replant in the treated areas. Otherwise, remove and replace the soil with fresh untreated soil, wait 3 weeks to replant in that area where the Crossbow was applied.
