Seasonal Bulbs to Plant for a Spring Garden Display

Why Autumn Is the Best Planting Season

There is a particular kind of pleasure in planting bulbs on a grey October afternoon. The garden looks tired, the borders are collapsing, and yet you are quietly burying next spring. Bulbs are the earliest reward a small country garden can offer: colour and scent before the trees have even thought about leafing. They ask for very little — a decent hole, reasonable drainage, and patience — and they fit into gaps that nothing else will fill. In a cottage garden, where space is tight and every square metre earns its keep, that is valuable.

The trick is to choose varieties that will come back year after year, rather than treating your spring display as an annual expense. In our damp, mild, occasionally waterlogged winters, that means paying attention to drainage as much as to colour.

Getting the Ground Right in a Damp Climate

Most bulbs rot rather than freeze. A British winter is rarely cold enough to kill them outright, but weeks of wet clay will see them off comfortably. Before you plant anything, fork over the top 20cm of soil and work in a few handfuls of grit or coarse horticultural sand. In heavy clay, it is worth planting on a small mound of grit so the bulb sits above the water table rather than in it.

• Depth: the reliable rule is three times the bulb's own height. That is roughly 10–15cm for daffodils, 15–20cm for tulips, 7–8cm for crocus and 8–10cm for snowdrops.
• Spacing: plant in generous drifts rather than neat lines. Odd numbers and irregular clumps read as natural; rows read as a municipal roundabout.
• Drainage: add grit to the planting hole, especially on clay. In pots, use crocks or broken slate and a loam-based compost rather than a light multipurpose.
• Protection: squirrels and mice will dig up crocus and tulips with enthusiasm. Plant deeper, lay a sheet of mesh over the ground, or top the bed with gravel.

If your soil is genuinely boggy in winter, plant in raised beds, in pots, or choose the damp-lovers listed below rather than fighting the conditions.

Bulbs That Naturalise Reliably

These are the ones that will multiply and settle in, giving you more each year with no intervention beyond leaving the foliage alone for six weeks after flowering.

• Narcissus: the backbone of any cottage spring. Smaller varieties such as 'Thalia' and 'Actaea' suit tight planting better than the big exhibition types, and 'Tête-à-Tête' is excellent in pots and grass.
• Crocus tommasinianus: the best crocus for naturalising, seeding about freely and shrugging off squirrels better than its larger cousins.
• Snowdrops and snowflakes: Galanthus nivalis and Leucojum aestivum both enjoy damp ground. Plant them in the green in spring if you can; dry bulbs are slower to establish.
• Muscari and Scilla: grape hyacinths and Siberian squill spread happily and give that soft blue haze under shrubs.
• Wood anemone and native bluebell: ideal for shady, leaf-mouldy ground beneath trees. Insist on native bluebells, not the Spanish sort.
• Camassia and Fritillaria meleagris: both thrive in moisture, flowering in late spring when the daffodils are over.

Tulips: Beautiful, Fickle, Worth It

Tulips are the exception to the naturalising rule. They dislike wet summers, and in heavy soil most will dwindle after a season or two. You have two sensible options: lift them once the foliage yellows in June and store the bulbs somewhere dry and airy until autumn, or treat them as annuals and plant fresh each year. Either is fine — the second is cheaper in time and dearer in money. Keep tulips out of boggy corners, plant them deep, and never plant them where tulips have grown before, as viral and fungal problems build up in the soil.

Layering for a Longer Show

In a small garden, the same square metre can produce three months of interest if you plant in layers. In a large pot or a generous planting hole, put the deepest bulbs at the bottom, cover with compost, add a middle layer, cover again, then set the smallest bulbs near the surface.

• Deepest: tulips or narcissi, at 15–20cm.
• Middle: hyacinths, camassia or alliums, at 10cm.
• Top: crocus, muscari or dwarf iris, at 7cm.

Finish with a light mulch and a handful of grit. Water once, then leave the pot outdoors somewhere the rain can reach it but where it will not sit in a puddle. In borders, the same principle works around herbaceous perennials: the bulbs flower and die back just as the perennials are filling out, hiding the yellowing leaves.

Planting in Grass and Small Corners

A rough patch of lawn is the classic cottage setting for daffodils and crocus. Scatter the bulbs by hand and plant them where they land — it looks far more natural than any planned arrangement. The one rule is that you cannot mow until six weeks after flowering, so keep this treatment to areas you are happy to leave shaggy until late May.

Everywhere else, tuck bulbs into the gaps: between the roots of shrubs, along a path edge, in the gravel by the front step, in a pot by the door for scent on a February evening. Label them, or draw yourself a rough plan, because by next autumn you will have forgotten precisely where everything went — and you will want to add just a few more.
