Answer: Hyacinth bulbs need to be dug out, separated every 3-4 years. If not, the flowers will gradually become smaller and less abundant. Dig them up after the foliage has died back, separate the young bulblets from the mother bulbs and replant them all either immediately or in the fall. The young bulblets may take a few years to flower but they should make it especially if you add a handful of bone meal per each hole for fertilizer.
