The Bulb Gardening Year:

Spring:

Replant pot-grown bulbs bought for an instant effect
Plant snowdrops and snowflakes bought "in the green"
Check for any signs of grey mould and spray with a fungicide to reduce infection
Stake tall bulbs
In late spring, plant out tender bulbs like gladioli and begonias
Deadhead flowers to concentrate energy into the bulbs
In late spring, clear away yellowing foliage to eliminate the homes for slugs and snails
Store container bulbs in a cool out of the way place
Feed potted bulbs with liquid fertilizer
Water indoor cyclamen as they get new leaves. Feed every two weeks

Autumn:

Plant commercial bulbs
Prepare heavy or compacted soil for planting by digging deeply and adding grit. Sprinkle a general-purpose fertilizer into the planting hole, and plant the bulbs at the required depth
Early autumn, plant containers with specially-prepared bulbs to flower in midwinter
Mark the location of your bulbs with labels to avoid disturbance later
Lift dahlias and gladioli and prepare for winter storage

Summer:

Lift and divide overcrowded clumps as the leaves die down
Collect dry seed in paper bags and store in a cool dry place
Clear away dying foliage to tidy the border and avoid the spread of disease
Rake over holes left in the soil by old bulb stems to lessen the chance of insects laying eggs in the tunnel. Mulch the whole area
Plant out pot-grown summer and autumn-flowering bulbs to fill gaps in the border
Re-pot winter and spring bulbs
Tie gladioli and tall dahlias to stakes for support
Buy new bulbs from your local garden centre or order from bulb catalogues

Winter:

Clear away any old foliage that might impede fresh growth. Mulch the site
Add a general purpose fertilizer to the surrounding soil
Store bulbs in a box in a cool, frost free place and check regularly for disease
Move groups of bulbs. Dig up the clump and place in the new position
Sow commercial bulb seed
If leaves show signs of disease lift the whole plant and dispose of it
Bring forced bulbs into a cool place to flower
Order late summer flowering bulbs
