Hyacinth bulbs are planted in fall so they can chill through winter and bloom in early spring. Unpack your bulbs as soon as they arrive and store them in a cool, dry, dark spot until you are 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 stands.
- Dig to depth. Set bulbs 6 inches deep, measured from the top of the bulb to the soil surface.
- Point the tip up. Place each bulb with the pointed end facing up and the flat, rooted base down.
- Space for effect. Space bulbs 3 to 6 inches apart, or plant in clusters of 5 to 10 for the fullest color.
- Backfill and water. Cover with soil, firm gently, and water once to settle everything in.
- Mulch lightly. Add 1 to 2 inches of mulch in colder zones to steady soil temperature.
Container Planting
- Use a deep pot. Choose a container at least 8 inches deep with drainage holes.
- Plant closer together. In pots you can space bulbs 2 to 3 inches apart for a packed display.
- Protect from hard freezes. Move window boxes and pots against a wall or into an unheated garage during extreme cold.
Watering
- Water at planting. One good soaking after planting is usually enough for fall.
- Keep moist while growing. Water during dry spells once shoots emerge and while flowers are open.
- Ease off after bloom. Reduce water once foliage yellows; dormant bulbs prefer dry soil.
Feeding
- Feed at planting. Mix a bulb fertilizer or bone meal into the planting hole.
- Feed again in spring. Scatter a balanced granular fertilizer as shoots break the ground.
After Bloom Care
- Remove spent spikes. Snip off faded flower stalks to keep beds tidy.
- Leave the leaves. Let foliage ripen and yellow naturally so the bulb can recharge for next year.
- Divide if crowded. Lift and separate clumps in summer every few years if bloom size declines.
