Hyacinth Bulbs,
Jan Bos (5 bulbs)

The optimal time to plant Jan Bos hyacinth bulbs is in the fall, just before the first hard frost. This allows the bulbs to establish roots before the winter season. In northern climates, plant in September or October, while in southern regions, planting in October or November is ideal. Jan Bos is hardy in USDA zones 4 to 8, making it well-suited to withstand cold winter temperatures.

Plant the Jan Bos hyacinth bulbs about 4 inches deep, with the pointed end facing upward, and space them 3-6 inches apart. After planting, water the bulbs well to settle the soil, but avoid excessive watering as this can lead to bulb rot. Applying a layer of mulch can help maintain soil moisture and protect the bulbs during winter. When planting in containers, ensure they have good drainage to prevent waterlogging.

Once planted, hyacinths don't require a lot of care. During the growing season, keep the soil consistently moist but not waterlogged. Fertilize the bulbs at planting time and again in early spring with a balanced fertilizer or bone meal to encourage healthy growth and vibrant blooms. After the flowers fade, remove the spent blooms but allow the foliage to naturally yellow and die back. This process is essential for the bulbs to store energy for the following year’s growth​.

To save the bulbs, wait until the foliage has completely yellowed and withered after the blooming period. Carefully dig up the bulbs, brush off excess soil, and allow them to dry in a cool, 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 them in a cool, dark place, ideally at temperatures between 50-60 F, until it's time to plant them again in the fall​.
