Planting Bulbs in Fall
Embrace the seasonal shift by planting bulbs in fall. It’s the ideal way to welcome cooler days while planning for next year’s stunning floral displays—this includes summer bulbs as well.
“We suggest buying your bulbs as soon as they’re available to ensure the best selection,” advises a bulb expert. “Once home, store them in a cool, dry place until you’re ready to plant. Smaller bulbs, like galanthus (snowdrops), should be planted as soon as possible to prevent drying out.”
1. Narcissus and Daffodils
Cheerful narcissus and daffodils are easy to grow and consistently bring joy. Most varieties bloom from early February to May with minimal care.
“Daffodils are cost-effective, pest-resistant perennials that pair well with other plants,” say experts. “They thrive in nearly all U.S. regions with a winter.”
Great as cut flowers, they prefer sunny locations in well-amended soil. Plant them at three times their depth.
Varieties range from petite 4-inch (10 cm) Heart-to-Heart daffodils to the impressive 20-inch (50 cm) ‘Dutch Master’. Some offer delightful fragrances, such as Poeticus Narcissi ‘The Bride’ and ‘Actaea’, while ‘Minnow’ and ‘Tete a Tete’ are popular early bloomers.
2. Tulips
Tulips are iconic for their stunning shapes and colors. They’re easy to grow and put on a fantastic show in pots and borders from March to late May.
Historically valued in Europe, tulips come in countless colors and forms. “You can select from ruffled Parrot Tulips to elegant lily-flowered varieties,” explained a bulb specialist.
Most tulips thrive in USDA zones 3-8. Plant them in pots with good compost, spacing them a few inches apart and at least three times their depth. Layering with other spring bulbs can create stunning arrangements.
Plant tulips until late November; cold weather helps prevent soil-borne diseases.
3. Allium
Alliums are show-stoppers with their globe-shaped blooms. They typically flower in late spring and thrive in pots or borders.
Best planted in October, they’re low-maintenance and attract pollinators while serving as striking cut flowers.
These ornamental onions, closely related to garlic, come in various shapes and sizes. ‘Purple Sensation’ is a popular choice, growing 24-30 inches (60-76 cm) tall with 3-4 inch (7.5-10 cm) blooms.
The impressive ‘Globemaster’ boasts flowerheads up to 6 inches (15 cm) across. For planting, place bulbs about four times their diameter deep and space smaller bulbs 3-4 inches (7.5-10 cm) apart.
4. Grape Hyacinth
Blooming abundantly from March to April, grape hyacinths (Muscari) form a vibrant blue or white carpet against lush green leaves. They thrive in moist, well-drained soil and can spread if not contained.
Standing at 6 inches (15 cm) tall, plant them in clusters about 3 inches (8 cm) deep and apart.
5. Ranunculus
Known as Persian Buttercups, these flowers shine in sunny yet cool spots. They bloom from late May through June, reaching 7-10 inches (20-30 cm) tall, ideal for borders or as cut flowers.
In fall, plant these unique tubers in HDSA zones 8-10, positioning them “eyes up, claws down” about 2 inches (5 cm) deep and 4 inches (10 cm) apart.
6. Trumpet Lily
These striking lilies thrive in HDSA zones 5 to 9. They shine in large pots or among perennials, producing numerous blooms on tall stems in May and June.
Their sweet scent attracts pollinators and can be especially enchanting in the evening. Plant bulbs about 2.5 times their height deep in semi-shady spots with good drainage.
7. Crocus
Crocus are delightful, blooming in various colors and attracting bees. Plant them from September to November for a prolonged spring display.
For naturalization, the early Crocus tommasinianus is a great choice, thriving in sunny locations. For containers, opt for bold varieties like ‘Jeanne d’Arc’ and ‘King of the Striped’.
8. Hyacinths
Hyacinths are early spring favorites known for their lovely fragrance. Perfect for pots or borders, they bloom from March to April.
These bulbs need a cool period of 40° to 45°F (4° to 7°C) for at least three months, making them suitable for HDSA zones 3 to 9. Plant them 4 inches (10 cm) deep and 3 inches (8 cm) apart. Remember to wear gloves while handling them.
9. Camassia
Camassia bulbs, native to North American prairies, bloom from May to June. They thrive in moist, humus-rich soil and prefer not to be waterlogged.
These recognizable plants feature bright blue spires that open from the base up. Plant them 3-4 inches (8 cm) deep and space them 7 inches (20 cm) apart.
10. Fritillaria Imperialis
The Crown Imperial fritillaria is a standout, reaching about 30 inches (80 cm) tall with vibrant bell-shaped flowers. These majestic bulbs flower in April and May before dying back.
Plant them deeply—around four times their height—in well-draining soil. Experts recommend planting them on their sides to prevent rot.
11. Snake's Head Fritillary
With their elegant bell-shaped blooms, snake's head fritillaries are enchanting in April and May. They thrive in meadows and can be planted in groups for a stunning effect.
Best planted 3-4 inches (8-10 cm) deep and spaced 4-6 inches (10-15 cm) apart, they prefer moist soil and should not be cut back until late summer.
12. Iris Reticulata
Iris reticulata offers a beautiful early spring display, available in various shades. They can be planted in pots or clumps for a lovely entrance.
Plant these bulbs in October, spacing them 4 inches (10 cm) apart and 3 inches (7 cm) deep. They thrive in well-drained soil in USDA zones 5-8.
What if I Forgot to Plant Bulbs in Fall?
If you miss the fall planting window, don’t fret. Check for healthy bulbs that are dry, without any roots or leaves starting to grow. Delaying planting increases the chance they won’t bloom next season!
You can also consider forcing bulbs for an earlier bloom.
