Tulip

In warmer regions with fewer than five frosts a winter, bulbs need about 6 weeks' chilling in the fridge before planting to flower well and produce long stems - a step cooler-climate gardeners can skip. Plant around Mother's Day once the soil has cooled.

Growing stages

  1. Germination & plantingAround Mother's Day (May), once the soil has cooled

    • In warmer regions with fewer than five frosts a winter, chill bulbs in the fridge for about 6 weeks before planting for strong flowering and long stems
    • Plant around Mother's Day once the soil has cooled
    • Space bulbs around 15cm apart in full sun
  2. Establishment

    • Watch for slugs and snails around emerging shoots
    • Water moderately as roots establish
  3. Vegetative growth

    • Aphids can build up on developing foliage
    • Tulip fire (botrytis) can affect leaves in damp, humid conditions
  4. FloweringSeptember to October

    • Watch for tulip fire (botrytis) on foliage and blooms in wet weather
    • Slugs and snails can damage flowers as they open
  5. Dieback & dormancy

    • Let the foliage die back naturally after flowering rather than cutting it down early, so the bulb can store energy for next year
    • In warmer regions many gardeners replant fresh bulbs each year rather than relying on old ones to rebloom well without proper winter chill
