Planting Spring Bulbs in October: Timing and Tips

Planting Spring Bulbs in October: Timing and Tips

By Michael Chen · October 6, 2026

Why October Is Ideal

Spring-blooming bulbs need 12-16 weeks of cold (below 48F) to develop. October planting gives time to establish roots before ground freezes.

Bulbs by Bloom Time

Early spring: Snowdrops, crocus, winter aconite (Feb-March)
Mid-spring: Daffodils, hyacinths, early tulips (March-April)
Late spring: Late tulips, alliums, fritillaria (April-May)

Planting Depth

Plant at 2-3 times bulb height. Large bulbs: 6-8 inches deep, 4-6 inches apart. Small bulbs: 3-4 inches deep, 2-3 inches apart.

Soil and Location

Well-drained soil in full sun to part shade. Amend clay with compost and sand. Add bone meal to the planting hole. Water well after planting.

Naturalizing

Scatter bulbs randomly and plant where they land. Try lasagna planting: layer large bulbs deep, medium in middle, small on top for successive blooms.
