Hyacinth bulbs are planted in fall so they can chill through winter and bloom in early spring. Unpack them right away, check that they feel firm, and store them in a cool, dry, dark spot until you're ready to plant.
Planting
- Pick your spot. Choose a site with full sun to partial shade and soil that drains freely; avoid low areas where water sits.
- Loosen the soil. Work the top 8-10 inches of soil and mix in compost if your ground is heavy clay.
- Set the depth. Plant bulbs 4-6 inches deep with the pointed end facing up.
- Space them out. Leave 3-6 inches between bulbs, and plant in clusters of 5 or more for the best color and fragrance impact.
- Water in. Backfill, firm the soil gently, and water thoroughly once after planting.
Watering
- Fall and spring. Keep soil lightly moist while roots and shoots are active; about an inch of water per week including rain.
- After bloom. Taper off watering as foliage yellows, and keep bulbs on the dry side through summer dormancy.
Feeding
- At planting. Mix a balanced bulb fertilizer or bone meal into the planting hole.
- Each spring. Feed again as shoots emerge to build up the bulb for next year's flowers.
After Blooming
- Remove spent flowers. Snip off faded flower spikes to keep the planting tidy.
- Leave the leaves. Let foliage die back naturally before removing it; it recharges the bulb.
- Mulch lightly. A 2 inch layer of mulch protects bulbs over winter in colder zones.
Forcing Indoors
- Pot them up. Plant bulbs in a container of well-drained potting mix with the tips just at the surface.
- Chill first. Keep the pot at 40-45 degrees F in the dark for 10-13 weeks, watering sparingly.
- Bring into light. Move to a bright, cool room once shoots appear, and blooms will follow in a few weeks.
