Hyacinths need at least a half-day of sun to flower well and store up enough energy for the following spring’s display. They grow in any well-drained soil. The flower heads are at their largest and fullest the first spring after planting; in subsequent years the flowers tend to be more loose and informal.
Note: Hyacinth bulbs can irritate your skin. Wear gloves when handling and plan on showering soon after planting.
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.
