Question: My grape hyacinths are running wild. They have escaped their original beds and have now spread all through my lawn. What can I use to stop them?
Answer: Grape hyacinths are beautiful in bloom, resembling early fields of bluebonnets from a distance. But, they can also be invasive. Remove any seed heads that form after they flower. Grape hyacinths spread quickly via their seeds. You can use a broadleafed weedkiller spray in the turf areas, so long as the leaves are growing vigorously. You’ll also want a 4-inch-deep edging at the interface between the planting area and the space where you don’t want the grape hyacinths.
