Tulip bulbs are planted in fall so they get the cold period they need to bloom the following spring. Unpack your bulbs as soon as they arrive and keep them cool, dry, and airy until planting day.
Planting
- Time it right. Plant in fall, roughly 6 weeks before the ground freezes, once soil temperatures have cooled.
- Pick a sunny spot. Choose a site with full sun to partial shade and soil that drains freely — standing water rots tulip bulbs.
- Dig to depth. Set bulbs 6 to 8 inches deep, pointed end up, spacing them 3 to 6 inches apart.
- Plant in groups. Cluster all 10 bulbs in one bed or container for the fullest, most dramatic show.
- Backfill and water. Cover with soil, firm gently, and water once to settle the bulbs in.
Watering
- Fall and spring. Keep soil lightly moist while roots and shoots are active; about an inch of water per week including rainfall is plenty.
- After bloom. Taper off watering as foliage yellows so bulbs can rest in dry soil through summer.
Feeding
- At planting. Mix a bulb fertilizer or bone meal into the bottom of the planting hole.
- Each spring. Scatter a balanced granular fertilizer as shoots emerge to support next year's flower bud.
Aftercare
- Deadhead spent flowers. Snip off faded blooms so energy goes back into the bulb instead of seed.
- Leave the leaves. Let foliage die back naturally before removing it — usually 6 weeks after bloom.
- Mulch in cold zones. A 2-inch mulch layer moderates soil temperature swings over winter.
Container Growing
- Use deep pots. Choose containers at least 10 to 12 inches deep with drainage holes and a quality potting mix.
- Protect in winter. In zones 3-5, move potted bulbs to an unheated garage or shed to avoid deep freezing and thawing cycles.
