Flower Bulbs - Guides
Beautiful bulb displays begin long before the first flower opens. Success depends on planting at the right time, choosing bulbs suited to your climate and site, providing good drainage, and planning bloom times so one display follows another.
Plant Bulbs at the Right Time
Timing depends on when the bulb flowers and how hardy it is. Many spring-flowering bulbs are planted in fall so they can establish roots and receive the winter chill they need, while tender summer-flowering plants are generally planted after the danger of hard frost has passed. Match planting time to both the bulb and your local climate rather than relying on the calendar alone.
Spring favorites include daffodils, tulips, hyacinths, crocuses, and alliums.
Give Bulbs the Drainage They Need
Many bulb problems begin in soil that stays wet for too long. Choose a site with suitable drainage and avoid planting bulbs where water regularly collects. Planting depth also matters: bulbs set too shallow may be less stable or more exposed to temperature swings, while planting too deeply can delay or weaken emergence in some species.
Plants such as lilies, gladiolus, and dahlias have different growing requirements, so check the needs of the plant rather than treating all bulbs alike.
Plan a Bulb Display from Winter to Fall
For a longer season of flowers, stagger bloom times instead of concentrating everything into spring. Snowdrops and winter aconite can start the display, followed by crocuses, daffodils, tulips, hyacinths, and alliums. Summer can continue with lilies, gladiolus, and dahlias, while Colchicum brings color into fall.
Help Bulbs Return and Flower Again
After flowering, resist the temptation to remove green foliage too early. Leaves continue producing energy that helps replenish the underground bulb for the following season. Remove spent flowers when appropriate, but allow foliage to yellow naturally before cutting it back.
Some bulbs, including many daffodils and crocuses, can naturalize and increase over time when conditions suit them, while some tulips perform more reliably when treated as short-lived displays.
Combine Bulbs Naturally with Other Plants
Bulbs are easiest to integrate when you plan for what happens after they finish flowering. Plant spring bulbs between perennials, ornamental grasses, or shrubs that emerge later and help disguise fading foliage. Repeat groups through a border rather than scattering single bulbs, and combine plants with different heights and bloom times for a more natural display.
Tall alliums can rise through emerging perennials, while dahlias and gladiolus can provide later color and excellent cut flowers.
