Growing Tips

Plant these bulbs in well-drained, sandy soil. Choose a site that receives full sun to partial shade. When handling the bulbs, consider wearing gloves, as hyacinths can cause mild skin irritation due to the oxalic acid that they contain.

When to Grow

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.

How to Sow and Plant

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.

How to Grow

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.

How to Save

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.

FAQ

When does Jan Bos hyacinth bloom?
These flowers typically bloom in mid-spring, offering deep pink-red flowers that last for 2-3 weeks, depending on growing conditions.

How tall does Jan Bos hyacinth grow?
It typically reaches a height of about 8 to 12 inches when in full bloom. This makes it an excellent choice for both garden beds and containers, as it adds a pop of color without overwhelming other plants.

Can Jan Bos hyacinth bulbs be left in the ground year-round?
Yes, in suitable climates (usually within USDA zones 4 to 8), the bulbs can be left in the ground year-round. However, in warmer climates (zones 9 and above), the bulbs may need to be lifted and chilled in a refrigerator for 6-10 weeks to ensure proper blooming in the following season. Bulbs will reproduce underground and it may be necessary to dig them up and divide or thin them from time to time.
