Plant Fall Bulbs for Spring Color
Get a solid spring show by planting bulbs in the fall. Timing shifts by region: September or October in the North, October or November in the South. Very warm areas may need pre-chilling. Use a frost date calculator to pinpoint your window.
What you need
- Bulbs (mix early, mid, and late bloomers)
- Slow-release fertilizer
- Well-draining soil
Steps
- Plant when soil temperatures drop below 60°F. In the Northeast and Rocky Mountains, go anytime in September until the ground freezes. In Georgia, plant October through late December. The Gulf Coast can plant through the end of December; the California coast goes through January.
- Aim for a hole two to three times as deep as the bulb is tall, leaving 2 to 3 inches of soil over the top. Specific depths vary: some sources suggest tulips and daffodils at eight inches, while others recommend 4 to 6 inches for tulips and 6 inches for daffodils. Crocuses sit 3 inches deep.
- Space large bulbs 3 to 6 inches apart and small bulbs 1 to 2 inches apart. Daffodils fit well at 6 inches apart; crocuses need 3 to 6 inches between them. Work slow-release fertilizer into the soil at planting time.
- Plant in full sun or partial shade. After flowers fade, leave the foliage alone so the bulb can feed itself for next season. In warmer climates, tulips often need replacing each year.
Why it works
Why fall planting works
Planting in fall gives bulbs time to grow roots before the ground freezes. Most bulbs require a 12- to 16-week chilling period to produce flowers. Proper depth ensures bulb survival and supports reliable flowering.

If it goes wrong
Warm climate challenges
In very warm areas, bulbs may not get enough chill; pre-chill them before planting. Tulips in warmer zones may not return and need replanting. Removing foliage too soon starves the bulb; wait until it dies back naturally.
