Grape hyacinths need dividing about every three to five years, or when they become crowded. In a couple of years dig up the bulbs after flowers have faded and the foliage has died back. Break off the old bulb on the bottom and discard it. Divide the remaining smaller bulbs and replant them about 4 to 5 inches apart.
