Fall Planting for Spring Bulbs

Spring Flowering Bulbs
Spring flowering bulbs are hardy plants that require minimum care. They provide color in the garden at a time when few other plants are in bloom. Since there are early, mid-spring and late spring flowering bulbs available, careful planning can achieve a colorful display from early March through May.


Bulb Planting Tips
Good drainage essential In heavy clay soils, work soil deeply and amend with peat moss or composted manure. Raised beds are perfect for bulbs providing excellent drainage. If this is not possible, try planting bulbs at a shallower depth than recommended to help prevent rot.

Planting time Spring flowering bulbs (crocus, hyacinths, daffodils etc.) can be planted anytime after the first frost usually in late September until the ground is frozen. Wait to plant tulips, however, until late October to prevent them from sprouting.

Planting depth As a general rule, plant bulbs twice as deep as their greatest diameter in medium to heavy soils. In sandy soils, plant three times as deep. Plant the pointed end up and the flat side down. Water in well to encourage root development.

Location Most bulbs need full sunlight. Select a planting site that will provide at least six hours of direct sunlight per day. Early blooming bulbs can be planted under the canopy of deciduous trees. Combine bulbs with low growing groundcovers, plant in the perennial border or tuck groups of bulbs among shrubs. Daylilies and hostas make great bulb partners, masking the dying foliage and providing a second show of their own.

Layering Bulbs always look best planted in groups rather than singly, but why not try an additional technique called layering? Get more bloom in the same space by planting different varieties of bulbs on top of each other at their respective proper planting depth. For example, plant a cluster of daffodils at 6” deep, glory-of-the-snow at 4” deep and crocus at 2” deep. You’ll have a fantastic spring show!

Fertilizing. Mix bulb fertilizer or “bulb booster” into the soil when planting to promote fall root development and spring flowering. Thereafter, fertilize before flowering in spring to support foliage and increase bulb size.

Spring Care Remove faded blooms to eliminate seed formation which reduces bulb growth. Allow foliage to die back naturally. Foliage can be removed when it has yellowed and fallen over.
