September is the perfect month to get a head start on your spring garden. Planting bulbs now ensures a burst of color and fragrance once the weather warms up. Whether you’re new to gardening or a seasoned green thumb, planting bulbs like tulips, daffodils, and hyacinths in fall sets the stage for low-maintenance, high-impact blooms. Here are five of the best bulbs to plant in September and everything you need to know to help them thrive.
1. Tulips
Overview: Tulips are one of the most iconic spring flowers, available in countless colors and varieties.
Why Plant Now: Tulips require a period of cold dormancy to bloom. Planting them in September allows their roots to establish before winter.
How to Plant: Choose a sunny spot with well-draining soil. Plant bulbs about 6–8 inches deep and 4–6 inches apart, pointy end up. Water thoroughly after planting.
2. Hyacinths
Overview: Hyacinths are beloved for their rich fragrance and vivid clusters of flowers in pink, purple, blue, and white.
Why Plant Now: Early fall planting ensures strong root growth and prevents bulbs from rotting in overly wet spring soil.
How to Plant: Plant bulbs 4–6 inches deep and 3 inches apart in well-drained soil. Place them near walkways or entryways so you can enjoy their fragrance up close.
3. Daffodils
Overview: Cheerful and hardy, daffodils naturalize well and return year after year. They’re also deer and rodent resistant.
Why Plant Now: September planting gives daffodils the chill they need to bloom on time in spring.
How to Plant: Plant 6 inches deep in groups of 5–7 for a natural look. Space bulbs 3–6 inches apart. Keep them in full sun to partial shade.
4. Alliums
Overview: Known for their globe-shaped purple flowers, alliums add architectural beauty to any garden and are pollinator favorites.
Why Plant Now: Early fall planting ensures tall, sturdy stems and larger blooms in late spring.
How to Plant: Plant bulbs 6–8 inches deep and about 6 inches apart in sunny spots with well-draining soil.
5. Crocuses
Overview: Crocuses are among the first flowers to bloom, sometimes even pushing up through snow.
Why Plant Now: September planting allows crocus bulbs to naturalize and spread over time, creating colorful carpets each spring.
How to Plant: Plant 3–4 inches deep and 2–3 inches apart in clusters for best effect. They thrive in full sun and well-drained soil.
