Hyacinth bulbs, whether planted outdoors in garden soil or in containers as indoor seasonal plants, are sweetly scented harbingers of spring. Their bright green, strappy foliage and large bloom heads in hues of pink, purple-white or blue always make a decorative statement. Grown indoors, hyacinths like bright, indirect light when in bloom, and light, even moisture around the bulb.
Place your potted hyacinth in a growing location that receives very bright, indirect light for six to eight hours each day. Some occasional direct sunlight is tolerable in the morning and afternoon, but should always be avoided in midday. When in bloom, move your hyacinth to a dimmer area to extend the bloom period.
Keep your hyacinth in a room with ambient temperatures ideally between 50 and 65 degrees F, and away from heaters or kitchen cooktops or oven, where they will become too warm. Placing the plant in a cooler area of the home overnight can compensate for day temperatures closer to 70 degrees.
Water your hyacinth bulb once a week lightly to keep the soil moist but not wet. In dry climates, twice-weekly light watering may be needed. Never allow more than the surface of the soil to dry out.
Cut off each bloom stalk as it fades to make way for a second or third stalk. Make the cut down at the bottom of the stem just above the soil line, being sure not to clip the tip of the bulb.
