Hyacinth Bulbs,
Blue Jacket (5 bulbs)

The best time to plant Blue Jacket hyacinth bulbs is in the fall, just before the first hard frost. This allows the bulbs to establish their root systems before winter sets in. In northern areas, this usually means planting in September or October, while in southern regions, October or November is more appropriate. Blue Jacket is suitable for USDA hardiness zones 4 through 8, meaning it can survive winter temperatures as low as -30 F. In warmer areas they may benefit from refrigeration. f you’re not sure how to find your area's first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

To plant Blue Jacket hyacinth, dig holes about 4 inches deep and space the bulbs 3-6 inches apart, with the pointed end facing upward. After planting, water the bulbs thoroughly to settle the soil, but avoid watering too frequently to prevent rot. Mulching the area can help maintain moisture levels and protect the bulbs from harsh winter conditions. If planting in containers, ensure the pots have adequate drainage to prevent waterlogging​.

Once established, Blue Jacket hyacinths require minimal care. Keep the soil consistently moist but not soggy during the growing season. Fertilize the plants at the time of planting and again in early spring with a balanced fertilizer to encourage strong growth and vibrant blooms. After flowering, deadhead the spent blooms but allow the leaves to yellow and die back naturally. This process helps the bulb store energy for the next year's growth.

Wait until the foliage has completely withered and yellowed after blooming. Carefully dig up the bulbs and brush off any remaining soil. Allow the bulbs to dry in a cool, dry, and well-ventilated area for a few days. Once dry, store the bulbs in a mesh or paper bag filled with peat moss or sawdust to prevent moisture buildup. Keep the bulbs in a cool, dark place, ideally at temperatures between 50-60 F, until it's time to plant them again in the fall​.
