Tulip Bulbs: When to Plant & How to Get the Best Display
Tulips are the one spring bulb worth planting late — here's why November beats September, and how to plant for a display that lasts.
Tulips are the exception to "plant bulbs as soon as you buy them." Unlike daffodils, tulips are genuinely better for waiting.
When to plant
Plant tulip bulbs in November, ideally once the soil has cooled and the first frosts have been and gone. Planting earlier, while the ground is still warm from summer, significantly raises the risk of tulip fire (Botrytis tulipae) — a fungal disease that spreads fastest in warm, humid soil and can wipe out a display before it flowers.
If you miss November, you can still plant into December in most of the UK — tulips are more forgiving of a late start than almost any other spring bulb, since they don't need as long a cold spell to flower well.
Planting depth and spacing

- Depth: three times the bulb's height — usually 15–20cm for a standard tulip bulb.
- Spacing: 10–15cm apart for a natural-looking drift; closer (7–10cm) for a dense, "block of colour" display in a pot or bed.
- Drainage matters more than soil richness. Tulip bulbs rot in waterlogged soil over winter — add horticultural grit to heavy clay, or grow in pots with generous drainage if your soil holds water.
Perennial or annual?
Most modern tulip varieties are best treated as annuals in UK gardens — they flower well the first spring but the display fades in subsequent years as the bulb splits and weakens. Species tulips (like Tulipa sylvestris or Tulipa clusiana) and a handful of reliable perennial varieties (Darwin hybrids in particular) are the exception — they naturalise and come back reliably.
If you want a repeat display without replanting every year, choose Darwin hybrids or species tulips rather than the showiest parrot or double varieties, which rarely return as strongly the second year.
After flowering
Deadhead spent flowers but leave the foliage to die back naturally — it's feeding next year's bulb. Don't tie or plait the leaves; it reduces the leaf area and weakens the bulb for next spring.
Quick reference
- Plant: November (December at a push)
- Depth: ~15–20cm, three times bulb height
- For a repeat display: choose Darwin hybrids or species tulips
- After flowering: deadhead, leave foliage to die back naturally
