Tips for Selecting Hyacinth Bulbs and How to Plant and Care for Them
The hyacinth bulb is the underground bulb of the hyacinth plant, appearing flattened-round or egg-shaped, wrapped on the outside in a membranous tunic, with layer upon layer of scales inside storing the nutrients needed for blooming. The plumpness of the bulb directly determines the quality of the later bloom; generally, the larger the bulb and the firmer it feels, the sturdier the flower spike and the denser the flowers.
When selecting, choose bulbs with intact skins and no mold spots or damage; if a gentle press feels hard, the interior is well filled, while a soft feel or an off smell may mean it has already rotted. The color of the hyacinth bulb's outer skin is often somewhat related to the flower color, for example purple skins mostly produce purple-toned flowers, which can serve as a small reference when buying, though it should not be relied on entirely.
Planting methods fall into two types: water culture and soil culture. For water culture, the water level should just touch the base of the bulb; first place it in a cool spot to encourage new roots, then gradually increase light once roots have formed. For soil culture, choose a loose, well-draining medium and keep the soil only slightly moist. Hyacinths mostly bloom in winter and spring, and the bulbs need a period of low temperature to complete flower bud differentiation, so planting in autumn better suits its growth pattern.
Common problems in routine care are bulb rot and "stuck arrow" (flower stalk failing to elongate). Bulb rot is mostly caused by too much water or unclean water, so control the water level and change the water regularly; stuck arrow is often related to improper temperature and light arrangements, so during the bud stage you can provide appropriate shading and cooling to encourage the flower stem to extend smoothly. After the flowers fade, cut off the flower spike and keep the leaves to continue growing so nutrients flow back into the bulb, which helps it bloom again the following year.
